INSTRUCTIONS AND PROPHECIES OF THE Blessed MOTHER ALIPIA GOLOSEEVSKY, Kyiv...
Angle grinder, simply - "Bulgarian", has three main areas of use.
- Cutting hard materials;
- Grinding with abrasives;
- Cleaning surfaces with brushes.
The technology involves holding the angle grinder with your hands during work.
However, for convenience and expanding the capabilities of the tool, many devices have been invented. Let's do a quick review:
Tripod for angle grinder
This mini machine allows you to solve the main problem when working with a grinder: if you hold the tool with both hands, who will fix the workpiece? AT this case, an angle grinder with a cutting disc is operated with one hand, and the second can hold and move the cut piece of metal.
Moreover, the tripod allows you to set the correct angle of cut, and the disk moves strictly vertically. The work is done efficiently and safely.
Devices for a grinder for cutting metal and other solid compact blanks, craftsmen have long learned to do it on their own.
The beds are assembled from a metal profile, automobile shock absorbers, or even plywood. A well-made machine is no less reliable and safe than a factory one.
IMPORTANT! When working with any machine - factory or home-made, you need to remember about correct position protective cover.
If your design is strong enough and provides protection for the operator, you can use a tripod for sawing wood. The main thing to remember about safety. main reason injuries - an uncontrollable grinder, escaping from the hands when the disc is jammed in a tree, has been eliminated. But the disc itself can still injure.
Therefore, in the manufacture of such a device, it is better to make the switch not fixed. For example - in the form of a foot pedal. Then you can instantly turn off the power if the device gets out of control.
When there is no need to work with wood, but you just need to cut a large number of metal blanks, there are simpler options.
Such a mount can be made in an hour, and ease of use will increase by an order of magnitude. If you know how your hands “fall off” after cutting fifty pegs from a metal corner, this design is for you.

Clamp for grinder
The second most popular way to add convenience when working with an angle grinder is to fix the tool motionless on a workbench or in a vise.
By installing the appropriate disk, you can get an excellent grinder, or just emery. The Bulgarian itself does not cease to be such. At any time, unscrew the mount - and proceed to manual work.
If you fix a strong stop with a slot across the disk, you can process parts with high accuracy while holding the workpiece in your hands.
The most popular is the disc sawmill from the grinder. Having made a solid frame, and securely fastening the angle grinder under it, you get a seasonal sawing machine, which, if necessary, is easy to disassemble.
At the same time, you still have a grinder and an excellent workbench (though with a slot in the middle of the tabletop).
If the tabletop under the angle grinder is turned, it will turn out great. Using such a device, you can quickly cut a plinth, baguette, profile from any material at a fixed angle.
One has only to install the appropriate disk, fix the tabletop at an angle of 45 degrees - and cutting trim for windows wooden house turns into pleasure.
This machine can easily cut paving slabs diagonally, diversifying the ways of laying it.
Something similar is also produced in an industrial version, but the cost of such devices will scare away not only home master- but also a small team of locksmiths.
wall chaser
Often when laying electrical wiring or cutting passages in the wall, the grinder is used as a. At the same time, comfort and safety during work leaves much to be desired. If you make a nozzle on the angle grinder with solid foundation- you can make cuts in the walls, as far as the diameter of the disk is enough.
In fact, this is an emphasis sole, which allows you to smoothly move the angle grinder along the wall, with a uniform effort. When you make this fixture for the grinder yourself - take the time and install a closed case with a pipe for connecting a vacuum cleaner.

Frazier
Since any angle grinder is equipped with a powerful motor with a gearbox, a stationary mill can be made from it. Again, provided that at any time the tool is removed from the homemade fixture, for use for its intended purpose. The shaft of the grinder is brought out into the hole of the workbench, a cartridge for milling heads is put on it - and not too hard woods can be processed.
IMPORTANT! Since the angle grinder is not designed for this type of work, you will have to take care of safety on your own.
Working with stone requires special care. If the disk is tilted, you can ruin the workpiece (which is not very budgetary), or split the disk. It is necessary to ensure the rectilinear movement of the grinder, while simultaneously controlling the depth of immersion.
Designed to automate the process special machine with guides along which the tool moves without deviating from the path.
In addition, the cutting angle can be fixedly changed, expanding the processing possibilities. It is difficult to make such devices, but if you develop intelligent drawings using computer modeling, you can design a machine no worse than a factory one.
cooking
It would seem, where is the grinder, and where is the kitchen? Unless during the repair you can see this tool there. However, in skillful hands Nothing is impossible for the USM.
With the help of a two-liter tin can from tomato paste, and a piece of galvanized steel - in half an hour you can make a mill from an angle grinder.
In the bottom of the can we make a hole along the diameter of the protective casing, instead of which it is put on. We put a galvanized strip on the shaft and fasten the nut for the metal disk.
We fall asleep half a can of grain - and after a few minutes we get coarse flour. After sifting, we get the quality no worse than the store.
For various works in a home workshop it is not always advisable to purchase specialized power tools, which, as a rule, are quite expensive. More relevant in such situations are do-it-yourself devices, which include a milling cutter from a grinder. With the help of such a device, the basis of which can also be a household electric drill, it is possible to perform various technological operations - milling, edging, forming spikes and grooves on the surface wooden blanks, training seats for door hinges and castles etc.
Materials used
Making a grinder with your own hands to equip a home workshop requires the fulfillment of certain conditions, the main of which are to ensure that the power tool is securely fixed in a vertical plane and that it moves relative to the surface of the workpiece.
In order to make your own milling machine from a grinder that meets the above conditions, you will need the following components and consumables:
- grinder or electric drill, the drive motor of which must be in working condition (in addition, the structural elements with which these devices will be fixed on the supporting structure must be strong enough and reliable);
- the base on which the future router will be fixed (as such a base, which should be highly reliable and stable, as well as provide ease of working with, the surface of a desktop or workbench can be used);
- thick plywood or thin sheet metal (of which you will make with your own hands that part of the router structure on which the grinder or electric drill will be fixed);
- welding machine(if sheet metal will be used in the design of your router);
- fasteners (clamps, screws, bolts and nuts);
- standard set locksmith tools.
Thus, to make a grinder from a grinder with your own hands, you will need materials that are in almost every home workshop or in any garage. Accordingly, in order to make such a machine and start using it, significant financial investments will not be required, which cannot be said about the situation when production model such a device.
Manufacturing algorithm
Do-it-yourself manufacturing of a milling cutter based on a grinder or drill is performed in the following sequence:
- From thick plywood, chipboard or sheet metal, the base of the milling machine is made, which consists of two walls located opposite each other. One of the walls of such a base, which is not used to fix the grinder or drill, can be made movable. This will allow you to change its spatial position depending on the length of the part that will be processed.
- A metal cone is fixed on the movable part of the future milling cutter, which is used to hold the workpiece during its processing.
- The tool through which processing is performed on a do-it-yourself machine is placed on the side of the frame. You can use tools of almost any configuration and any size on such a router.
In the event that the milling machine will not be manufactured on the basis of electric drill, and on the basis of a grinder, a special adapter will have to be included in its design, which will ensure the fixation of the sleeve used to rotate the workpiece. If the basis of a homemade router is a drill, then such a sleeve is simply fixed in the power tool chuck.
Thus, making a router from a grinder or an electric drill with your own hands is simple. To do this, you don’t even need to invent your own device design - just use ready-made ideas that have already been tested in practice by many home craftsmen.
The grinder, which is also called the angle grinder (angle grinder), is a universal device. With this tool, you can perform various types of processing, such as cutting, grinding, polishing, chasing, etc. The angle grinder is suitable for working with stone, metal, and wood blanks. The effectiveness of the device depends on the correct selection of the nozzle for the grinder. In order not to make a mistake when choosing the right product, you need to study its types.
Processing of almost any material is carried out using angle grinders with a variety of nozzles
On the modern market you can find many varieties of circles for angle grinders. A huge number of modifications can confuse an inexperienced person. Each type of nozzle has its own operational features that determine the design of the product. Differentiation of such instruments occurs according to the following criteria:
- appointment;
- material of manufacture;
- size.
Today you can find many circles on the grinder, which are used for processing metal, wood or stone parts. The purpose of the product is determined by its labeling. It should be noted that some types of nozzles are universal. For example, a stone wheel is often used to cut ceramic tiles, concrete and brick products.
However, most discs are only suitable for highly specialized work. Nozzles for metal should never be used when cutting wooden logs or planks. And the circles that are used for roughing steel are not usually used for stainless steel.
Useful information! Why is Bulgarian called Bulgarian? The answer to this question is very simple: in the USSR, the first samples of this device appeared in the 70s. They were delivered from Bulgaria, so this name was assigned to the device.
Angle grinders are used for cutting and grinding materials. If desired, you can choose a circle for processing glass, plastic or marble slabs. All tools for angle grinders are divided into types according to the class of processing, as well as the degree of rigidity.
Classification of nozzles on angle grinders depending on the type of work
Nozzles, which are used for cutting various materials, can be used to perform many operations. Each fixture is different unique properties and design. Depending on the purpose of the nozzle are:
- cutting;
- saw;
- peeling;
- cleaning (grinding);
- for making seams;
- polishing.
Cut-off. Such circles are used when it is necessary to cut or cut the material (rough). The cutting nozzle for angle grinders has the shape of a disk equipped with a cutting edge. In some cases, such circles are equipped with a solid cutting part, and sometimes with a segmented one.
Saw. By name it is clear that such products are used for cutting various parts made of wood. The peculiarity of these nozzles is that their cutting part has teeth. Such discs are widely used for sawing wood, drywall, chipboard and fiberboard. With the help of a saw blade, you can make a smooth cut of ordinary and laminated boards. It is worth noting that the teeth of the saw blades for the angle grinder may differ in shape, which affects their operational purpose.
Peeling. Such nozzles are used for grinding metal, concrete and wood blanks. Using a similar disc, you can easily remove from the surface old layer paint or varnish. Grinding wheels are also used to remove primer. If necessary, these products are used for grinding.
Strippers. Cleaning nozzles are included in the peeling group. They are circles, the edges of which contain a metal wire. Cleaning discs are used to remove rust from metal surfaces, as well as for the elimination of other types of persistent pollution. Most often they are used to prepare pipes for painting.
One of the most common types of cleaning nozzles is the petal circle. This product is used for processing workpieces made of metal, wood and plastic. The petal circle is a disk, along the edges of which small pieces of sandpaper are fixed. Depending on the nature of the work, the grain size of the working components is selected. On the modern market, you can find varieties of petal disk:
- end;
- batch;
- having a mandrel.
A cleaning (grinding) nozzle for a grinder with a mandrel is used when it is necessary to ensure high accuracy. Many products belonging to this group are used to remove burrs after cutting metal and plastic pipes.
Useful information! With the help of cleaning wheels, the finishing of welds is performed.
Stitching attachments are used to arrange stitches in stoneware, concrete, and asphalt pavement. Seam wheels are specially designed to perform this kind of work.
Polishing. These products are used for polishing surfaces. Most often they are used after grinding. This group includes the following types of discs: felt, felt, as well as an emery wheel. Velcro is used to fix them on the tool, so they are very easy to change.
Nozzles for grinder: classification by material
For the manufacture of nozzles that are used while working with angle grinders, various materials are used. All of them are highly efficient, and also made with safety in mind. For example, many metal wheels have special slots filled with copper to prevent the disc from overheating during operation. Consider what materials you can buy circles for angle grinders.
diamond circle. Such products include two components. The first of these is a steel base, and the second is a diamond coating. Such discs are used for processing metal blanks, as well as products made of stone, concrete, ceramics and glass. The diamond wheel for the grinder is characterized by high efficiency and accuracy of work. With it, the thinnest cut of the workpiece is performed.
"Turtle". Such a nozzle also has a diamond coating, however, the base in this case is represented by flexible rubber, which is characterized by high strength. The disk got its name due to the corrugated structure. Diamond-coated circles are fixed to the base with Velcro.
Carbide disc. For the manufacture of such devices, metals are used, the alloy of which forms a strong connection. The edges of such circles contain solder, which includes high-carbon molybdenum steels. Also, the solder contains impurities of chromium and nickel, which increases the resistance of the product to adverse operational factors. Such discs are used for cutting metal (less often - wood).
The "turtle" nozzle has a corrugated structure, and the diamond-coated circles are fixed to the base with Velcro
Abrasive. Such a circle is made of latex paper, the main characteristics of which are density and resistance to moisture. Similar devices for angle grinders include a special reinforcing mesh in their structure. An abrasive layer is applied to such a base. Circles of this type used for grinding may have a polymer base.
Cleanup. This disk includes a metal wire, with the help of which paint, varnish and heavy dirt are removed from the treated surface. The diameter of such a wire is selected depending on the nature of the work.
Note! Separately, it should be said that the nozzles used for angle grinders include support plates. These products are made from polymer materials or hard rubber. They are used in combination with some grinding and polishing tools.
Cutting devices for grinders: their features
Cutting a wide variety of materials is the most popular operation for which an angle grinder is used. A very important point necessary for this task is the competent selection of nozzles. The choice is made depending on what material will be processed. For example, for cutting metal cutting wheels, for the production of which a crystalline mineral - corundum is used.
All circles for the grinder are color-coded depending on their purpose. For example, for cutting metal objects, it is customary to use discs with blue markings. It is important to remember that cutting wheels are recommended to be installed on angle grinders with speed control.
Cutting products for metal processing are also differentiated by dimensions. The main geometric data of such nozzles include:
- outside diameter;
- thickness.
Metal cutting discs are available for three types of angle grinders: small, medium and large. The diameter of these products varies from 115 to 230 mm. Circles of 125 mm are very popular. Less common are products with a diameter of 150 and 80 mm.
The thickness of such devices ranges from 1 to 3.2 mm. Accordingly, large circles are made thicker in order to have sufficient rigidity. And for small nozzles, this indicator can be completely different.
Cut-off bits, which are used to work with stone and concrete, are made of a completely different material - silicon carbide. Such an abrasive ensures the efficiency of the angle grinder when cutting white brick, as well as slate. The most common type of grinder is angle grinder 125 (with speed control). This is due to the fact that it is the most functional and has a low weight.
Silicon carbide is not suitable for processing red bricks. In this case, it is customary to use circles with diamond coating applied to a metal base.

Such products have a green marking that allows you to accurately select them for the grinder. Photos of silicon carbide products, as well as other types of discs, make it possible to visually appreciate their differences.
Note! Different discs are used to cut wood. This can be a chain circle, along the edges of which a chain from a chainsaw is installed, or a metal product with teeth (circular).
Experts recommend taking into account the technical characteristics of wood when choosing a nozzle for a grinder. A chain saw is most suitable for working with wood products. This material It has a high viscosity coefficient, so it is the most difficult to process. Before starting work, it is recommended to study the safety rules and take the necessary precautions.
Peeling attachments for grinder: varieties
To remove paint and varnish materials and rust, special nozzles are used - peeling. This group includes several types of discs, which differ in the material of manufacture and characteristics. In order to remove a layer of paint from the pipe, metal brushes are used. Bulgarian is often used for such work. The brushes can be in the form of a bowl or a disk with coils of metal wire around the edges.
In order to select the required processing intensity, it is required to select the desired wire diameter. In this case, a certain pattern can be traced. For a rougher impact, nozzles with a larger diameter wire are used. Accordingly, thinner wire is used for gentle processing.
The design of the nozzles takes into account two options for placing the wire. In the first case, it is collected in bundles of various thicknesses, and in the second, it is located freely. Nozzles for grinders for removing paint from metal products are very popular. It is worth noting that, in addition to brushes, there are other devices that belong to the peeling group, such as:
- diamond peeling nozzles;
- abrasive grinding wheels.
They have a lot in common. However, the location of the abrasive material in this case is different: it is located along the perimeter of the disk. Thus, the processing is done in a slightly different way. It is important to remember that diamond-coated roughing heads are not commonly used for metal workpieces. They are used to remove layers of stone, concrete and other similar materials.
In turn, abrasive grinding nozzles, which also belong to the category of peeling ones, are used when working with metal products. With these tools, you can perform rough processing of the workpiece. There are many uses for these products. Their design is excellent for grinding metal. Nozzles for a grinder of this type are used for processing welds, as well as for. The thickness of these products may be different, but it should not be less than 5 mm.
Useful information! The universality of the angle grinder has influenced its wide distribution. Bulgarian is used in almost all areas of construction. This tool is used for cutting, grinding, polishing and other processing options for a wide variety of materials.
Grinding nozzles for grinder: rough and gentle processing
Grinding is one of the most popular processes for which angle grinders are used. With the help of such a tool and a set of nozzles, it is possible to carry out rough and gentle processing of metal, stone and wooden surfaces. As a rule, grinding precedes polishing of workpieces. The nozzles that are used in this case may consist of sandpaper or felt material.
The petal disk for the grinder was widely used. This tool consists of a circle (base), along the edges of which sandpaper petals are fixed. They may have different grain sizes. This indicator is selected depending on the nature of the work.
The use of a petal wheel allows for roughing workpieces from different materials. It can also be used for fine sanding. For finishing fine-grained petals are used.
Today you can find another type of grinding discs for grinders. Some abrasive products are fixed to the base with a special Velcro. To use such a circle, it is necessary to screw it onto the tool spindle.
Polishing is the softest wood treatment. For polishing work, which relate to the finishing stage of turning a particular material, special felt discs are used. And also on the tool market you can find circles, the working part of which consists of a dense fabric. Nozzles for polishing grinders are very popular when working with wood, as their use allows you to bring the surface of the material to the smoothest possible state.
Nozzles on the grinder for rough processing of various materials
For rough grinding of various surfaces, special discs are used, which have their own characteristics. Rough processing of wood is aimed at eliminating knots, as well as a layer of bark. The use of such nozzles for metal blanks allows you to remove paint and rust.
Today, there are several types of nozzles for grinding on a grinder. For example, peeling discs are very popular. Among them there are products that are used for processing stone and concrete (diamond) and abrasive wheels used for metal parts.
Roughing products are often used to remove an old layer of paint. In some cases, they are used to remove varnish. Another common variant of the nozzle on the grinder is the brushes. The design features of these elements are reflected in their effectiveness. The disc, which has a metal wire, is able to quickly remove paint from a metal surface.
Note! In the building materials market, you can find end circles for angle grinders. Such products are used when it is necessary to align the cutting line of the board. Aligning the ends with an oblique cut is done quite often, so this tool can be called indispensable.
Separately, it should be said about the nozzles for polishing cars. For rough processing paintwork(LKP) machines use special wool discs. The material in such a circle can be located freely or twisted into dense threads.
Also, abrasive discs are used for rough processing of cars, which are distinguished by high functionality and longer operational life.
Today you can find other nozzles on the grinder for polishing cars. For example, felt and felt discs are very popular. To finish the paintwork of the car, vulcanite nozzles are used, the main material of which is rubber.
Nozzles for grinder for grinding: gentle treatment
For coarse grinding of certain materials, petal nozzles are used primarily. They, as mentioned above, consist of petals located close to each other and having an abrasive coating ( sandpaper).
The grain size of the petal nozzles can be different. It is selected depending on the nature of the work. It is worth noting that the design of this grinding nozzle allows it to serve for quite a long time, which is a definite plus. In shape, individual petals resemble a trapezoid.
The second type of nozzles, which are classified as soft, are grinding wheels. They are made of sandpaper, felt or dense fabrics. Discs of this type are fixed with Velcro on a plate basis. They are usually sold in a set.
For processing wood, a kit is used that includes 5 discs. They all duplicate each other. In case of wear of one circle, it will not be difficult to replace it with a new nozzle. Similar products are used for finishing wooden surfaces. There are other nozzles on angle grinders that are used for grinding wood. For example, wood cutters for grinders are very popular.
Felt circles, as well as products that include dense fabric in their design, are used for wood processing. It is important to remember that for grinding with the help of such circles, it is necessary to use a special wax paste. It is applied to the surface of the part before starting work.
Another type of nozzles that is used for finishing wooden surfaces is cup products. They consist of nylon fibers, which together form a fairly dense coating.
What discs for grinding concrete and metal are used most often
For grinding concrete, two types of nozzles are used on angle grinders: diamond and abrasive. It is important to remember that its effectiveness depends on the diameter of the circle. The larger the disk, the more load it can carry.
Note! Discs of this type are actively used in the installation of concrete screed. Its polishing can significantly improve strength characteristics. At home, a grinder equipped with a special nozzle is enough to perform a similar operation.
Nozzles for a grinder for grinding concrete can be purchased on the market, in a hardware store, or you can place an order via the Internet. To date, there are two methods of grinding this material:
- dry;
- wet.
In the first case, the operation is performed using special disks. Dry grinding of concrete is highly efficient, but it also has some disadvantages. The main disadvantage is abundant dust formation. Before starting dry grinding, it is necessary to prime the surface, which will increase its strength.
Wet (or wet) grinding of concrete differs from the previous method in that it involves the use of water, and this avoids the formation of dust. This type of grinding is considered to be of higher quality, however, when using a grinder, it is not possible.
It is important to remember that grinding and polishing with a grinder are two completely different processes. When polishing, the surface of the material is processed until it is smooth. In turn, grinding is necessary to level the surface.
Grinding of metal products is carried out using special discs. They include the following materials: silicon carbide, electrocorundum, etc. And also in the composition of such circles there are special fiberglass meshes.
For grinding metal, various brushes are used, which consist of a wire located on a metal base. In addition, today you can purchase other, more technological nozzles for the grinder. The tape file is a direct confirmation of this. It is used for polishing, grinding and removing rust. It is worth noting that the angle grinder must have smooth speed control, which is necessary condition to use this nozzle.
Grinding discs for metal are used for the following operations: sharpening tools, fine finishing of welds, as well as cleaning the surface from rust and paint. When choosing nozzles for metal, you must first be guided by how much work you have to do.
Nozzles for a grinder for grinding wood: peculiarities
For sanding wood surfaces, petal and round nozzles are used. In the first case, sandpaper is fixed around the perimeter of the disc. In turn, round discs provide for fastening emery wheels with Velcro. Both options for woodworking attachments are quite convenient. In some cases, such tools are equipped with a special adapter that allows you to use the disc on a drill.
Useful information! Nozzles for grinders for grinding wood can have different grain sizes. Her choice depends on the type of work. Coarse-grained products are used for rough, rough processing, and fine-grained products are used for fine finishing.
Which tool is best for wood sanding? This operation can be performed using an angle grinder or a special grinder. The choice of tool depends on the purpose for which the surface will be processed. If grinding is necessary in order to prepare the wood for painting, then you can use a special disc on the angle grinder.
For varnishing wood, it is best to process it with a grinder. There are several varieties of this equipment. Longitudinal type devices are so called because of the direction of movement of the emery tape. In turn, in the vibration variety, circles are used on which abrasive material is applied.
Metal brushes for grinders for rust cleaning and woodworking
Many people believe that with the brush heads used for angle grinders, only steel products can be cleaned. However, such tools are also used when it is necessary to process wooden details. For wood, nozzles with brass wire are used.
Brushes have some advantages over abrasive discs. They have a long service life and lower cost. They are used in the case when you need to remove rust or old paint from the workpiece. Separately, it should be said that brushes are indispensable tools for processing hard-to-reach places.
Brass nozzles on angle grinders for woodworking allow you to remove paint material as efficiently as possible. Brushes are used for more than just cleaning surfaces. This tool is also used when it is necessary to artificially age the wood. This process is called brushing.
Brushing is used to create unique design interior items. Using the angle grinder, you can process small items. AT industrial scale no such tool is in use. The nozzle for brushing on the angle grinder allows you to highlight such elements of wood as rings and various irregularities.
Metal brushes are able to quickly and effectively remove old paint from steel pipes, remove rust and plaque. When choosing such nozzles, it is imperative to pay attention to their rigidity, since the operational efficiency of the brushes depends on this indicator.
To use such a nozzle, you must have an angle grinder, which provides for the possibility of installing a second saw blade. And it is also necessary that it has an outlet for connecting a vacuum cleaner. Shtrobleniye generates a fairly large amount of construction debris. To protect the master during work, a casing for the angle grinder is used.
Note! Strobe attachments are not suitable for all angle grinders. The device must be powerful enough to provide the desired result. The minimum angle grinder in this case should not be lower than 1500 watts.
Before buying discs, you should pay attention to the length of the shaft. This element must necessarily have sufficient length necessary to install an additional circle. The second disk is needed to form the opposite wall of the groove.
For use, you must have a grinder, which provides for the possibility of installing a second saw blade
The dimensions of the disk itself also play an important role. This is due to the fact that the diameter of the circle affects the depth of cut and work efficiency. Security is also important point, depending on the dimensions of the nozzle on the grinder for chasing.
Such a design affects the nature of the load: it becomes more uneven. Therefore, when choosing a tool, it is necessary to pay attention to what type the bearings belong to. Ordinary ball parts fail much faster. Experts recommend using angle grinders with roller bearings for chasing. Needle products are also suitable for such work.
During operation, the chasing wheels must act in one direction - towards the master. Otherwise, the tool will be repelled from the work surface.
Before starting work, it is necessary to attach a nozzle to the angle grinder for a vacuum cleaner to the angle grinder. A tube is fixed to it, which is required to remove dust and larger particles. During operation, it is necessary to hold the tool firmly to prevent the discs from jumping off.
If necessary, the grinder attachment can be installed on a chainsaw. It is easy to buy such a product in any store that specializes in the sale of gas tools. Its installation is described in detail in the instructions, so there should be no problems.
Some chainsaws are simple in design, so it is much easier to install a grinder on them. For example, the Stihl chainsaw is very popular. The grinder attachment on the saw may fit some models, compatibility with which is not indicated in the technical documentation of the tool. In order to choose the nozzle correctly, experts recommend comparing the diameter of the crankshaft of the saw with the same indicator of the grinder hole.
A variety of nozzles on the market today makes it easy to change the appointment and performance characteristics devices. However, not everyone knows about the possibility of converting a chainsaw into a cutting and grinding tool. Most people are familiar with the reverse. – nozzle saw on the grinder.
Note! When buying such a nozzle for a saw, one important point must be taken into account. The selection of the grinder is carried out for a specific chainsaw model.
The attachment pulley, which is the drive one, can be different type. Before buying, you need to evaluate the compatibility of the chainsaw main star and the nozzle pulley. If the tool does not fit, then it is not possible to install it instead of the clutch.
Varieties of pulley nozzles grinders on a chainsaw
It should be noted right away that there is no official classification of nozzle pulleys of this type. Consider the most common pulley options. The first of them belongs to the Stihl 180 chainsaw. It has some design features. Such a pulley looks like a closed bowl. A similar element is not collapsible and is used in the following modifications of the Stihl saw: MS 180, MS 250 and MS 170.
Nozzle grinder for chainsaw Stihl 180 can be installed on the drive sprocket of the saw without removing the clutch. In this case, there is no bowl at the pulley. There are several variants of this design, which are classified depending on the pitch of the sprocket. The main advantage of this type of nozzles is that they are very easy to mount. It is also worth noting their reasonable cost.
Professional type chainsaws are distinguished by the fact that they have a clutch, the sprocket of which, if necessary, can be replaced. For such devices, special pulleys are used. The cost of this tool is more, however, its quality characteristics will be better.
Attachment angle grinder for chainsaws Calm, Partner, Taiga, etc. is used when you need to make an even cut on wood or metal. During operation, you must be careful, and before starting it, you must definitely check the correct installation of this nozzle.
Rating of grinders in 2018: the best models in terms of cost and quality
To date, there is a huge variety of angle grinders, which differ in the manufacturer, technical specifications and cost. Some models are very popular, as consumers note their advantages over standard devices. Before purchasing this tool, it is recommended to pay attention to the angle grinder rating, which contains the best representatives that have certain advantages.
Interskull UShM-125/1100E. This model of the Interschool brand belongs to the budget segment. Her distinguishing feature- the highest power among inexpensive angle grinders. Many users note another advantage of this device - soft start.
The cost of this tool is only 3900 rubles. Of the minuses, only a large mass of the product can be noted. It is used for discs with a diameter of 125 mm. For circles of 230 mm, there is a heavier model from Interschool - angle grinder 230.

Safety precautions when working with discs for grinders
Use of any construction tool has its own nuances. Before using the grinder, it is necessary to study the safety precautions in detail, since its improper operation can lead to serious injury.
The safety of the angle grinder is primarily ensured by a protective cover. In the event of a disc split, this element protects the master from splinters. In no case is it recommended to remove the casing from the grinder.
The direction of rotation of the disc is also important. It is impossible to allow situations in which the movement of the circle will be the opposite of the master. This can lead to the fact that the grinder will break out of your hands. The direction of movement of the disk should always be towards the person working with the angle grinder.
For home use, it is recommended to purchase an angle grinder with speed control. This is because different materials require different wheel speeds. One of the most important rules: It is strictly forbidden to use discs that do not correspond to this or that material.
And, finally, the last thing to remember is that angle grinders cannot be used for other purposes. The passport of the device clearly indicates what this or that angle grinder can be used for, as well as the limits of its functionality. Subject to all of the above rules, working with an angle grinder will be as safe as possible, and the tool itself will last more than one year.
An angle grinder is a very common tool that can be purchased on the market, in a store or ordered online. This device has many options for use precisely due to the possibility of changing nozzles. Before purchasing a grinder, you need to take into account what it will be used for and study the range of discs. Choosing the right nozzle will allow you to do the job quickly and efficiently, and most importantly - safely.
The capabilities of the grinder can be expanded not only through various nozzles, but also by installing it on special homemade devices. As a result, you can get a cutting machine, with which it becomes possible to accurately cut metal blanks at any angle. In addition, the grinder can be installed on a carriage, and the resulting machine can be used for cutting sheet steel.
In order to understand how to make a cutting machine out of an angle grinder (angle grinder), you can look at various drawings on the Internet. But they will not help much, since all the dimensions of the parts will still have to be selected based on the size of the grinder you have. Options for the execution of devices can be both simple and more complex, requiring the ability to handle a welding machine.
Option 1
To make this device for the grinder, you will need welder skills. So, you need to do the following.
First, cut 2 small pieces from the corner (50x50 mm). Their size is selected based on the dimensions of the gearbox block of your angle grinder.
Next, drill holes in them with a diameter of 14 mm and screw the corners to the angle grinder, as shown in the next photo. If you do not have suitable bolts, then you can use threaded studs M14. Just be careful that the bolts are not too long. Otherwise, in some models of angle grinders, they can cling to the impeller located in the gearbox housing.
Without removing the corners from the grinder, grab them by welding. After that, the corners can be removed and scalded well.
Clean the welds with a grinder grinder.
Then you need to make rotating arm support to which the machine will be attached. To do this, select 2 pipes of such diameters that one can easily enter the other without much effort.
For a more accurate cut, masking tape can be glued to the tubes and draw a line on it.
Then, turning the tube, carefully cut it with an angle grinder. A piece of pipe of a smaller diameter should be shorter by 20 mm (thickness of 2 bearings) - it will serve as a spacer.
Choose 2 bearings suitable for its inner diameter for a thicker pipe. After that, insert a thin tube into a thick one and press the bearings on both sides.
Then insert the stud into the bearings. Be sure to put a washer in front of the nut.
When the swivel mechanism is ready, you need to weld a small piece of the corner to it.
The next step is to rack for rotary mechanism from the same corner 50x50 mm. To make the segments the same length, the corners can be pulled together with a clamp and cut off.
Also, without unwinding the clamp, they can be drilled immediately.
Attach corners with drilled holes to the ready-made swivel block using nuts.
Weld a longer corner to this rack, as shown in the following photos.
Now you need to decide on lever length, on which the angle grinder will be fixed. This is done by selection, based on the dimensions of your grinder. You can lay out the details on the table and calculate the approximate dimensions of the lever, which is best made from 2 square segments profile pipe 20x20 mm.
Pipes must also be clamped with a clamp and cut to the same size.
After all the parts are ready, they can be welded together, as shown in the following photos.
At the next stage, you can attach the angle grinder to the finished structure and check again what came of it.
The ready-made pendulum mechanism for the grinder is easy to install on any flat surface, for example, on the workbench. Also, this design can be installed on a table specially made for it. For a more rigid fastening of the mechanism, small pieces of corners can be welded on both sides of the long corner, and holes drilled in them.
In the following photos you can see how the finished fixture for angle grinders is fixed on the table (in this case, a metal frame is used).
It is very important to set a right angle between the plane of the cutting disc and the plane of the table. Put the square on the table and move it to the abrasive wheel mounted on the angle grinder. If initially you managed to weld the fixture so that the angle between the planes was 90 degrees, then that's good. If you notice a deviation from right angle in one direction or another, then you can correct the situation with a crowbar or a long profile pipe, for example, 60x20 mm.
To prevent the part from moving when cutting, a corner can be screwed onto the table, which will serve as an emphasis. Also, for an accurate cut, the table can be easily improved with a simple vice made of a nut welded to it and a stud of the required length screwed into it.
Next, you need make a protective cover. It is done taking into account the maximum diameter of the cutting disc, which is permissible to put on a specific model of angle grinder. To make it easier to determine the dimensions of the casing and places for attaching it, you can first make a template, for example, from a piece of cardboard.
In this case, the casing will also serve as a limiter for cutting tool, which does not allow him to go too deep into the table during the processing of the part.
It will not be superfluous if for a lever with a grinder attached to it make a spring. In this case, this is easy to do: insert a smaller tube from the back of the rod and attach a spring to it, as shown in the following photo.
On this, the manufacture of a cutting machine with your own hands, in which an angle grinder is used as a drive, can be considered complete.
Option 2
Another version of the fixture for the grinder, with which it will be possible to cut metal blanks, is done as follows.
Thus, a simple cutting machine was obtained. To give additional rigidity to the attachment of the device to the lever, you can use clamps, after laying a wooden block between the angle grinder body and the pipe, for example.
For precise cutting, so that the workpiece does not move, you will need to screw the corner to the table.
For a little grinder a similar version of the device is also suitable, only the angle grinder will be mounted on metal strip: on the one hand, with a bolt to the angle grinder itself, and on the other, with the help of a clamp.
For a powerful angle grinder the fixture is made according to the same principle, but from profiles of a larger size than in the figures above.
It is not necessary to use dumbbells as a counterweight. All you have to do is find the right spring.
Option 3
This fixture option is the simplest for making your own. It is made without a traditional stand (rack) for a rotary unit. All you need is one door canopy, a metal strip and a rubber band (you can use a rubber band from a hand expander).
The construction is done as follows:
- in the metal strip, on one side, drill holes for the door canopy, and on the other, for the bolt with which the strip will be attached to the grinder;
- screw the angle grinder and the canopy to the strip;
- screw the canopy to the table;
- fasten one end of the elastic to the edge of the table, and the other to the holder (handle) of the angle grinder.
In just a few minutes you will receive a high-quality cutting machine. This device is also mobile, because it can be carried with you in a tool case, and, if necessary, mounted on any flat surface.
When installing this fixture, do not forget to fix a corner on the table to rest the workpiece in it.
Cutting sheet hoist with angle grinder
To cut sheet metal, you will need to purchase special carriage, which moves along the guide (profile square pipe).
But as practice shows, the cost of a good carriage is high (more than $ 100), so you can make it yourself. Since this process is quite difficult to describe, you can understand the manufacturing technology of this slider from this video. With the help of the device, you can cut not only steel, but also ceramic tiles, and porcelain stoneware.
Please note that when cutting ceramics, a lot of dust is generated. Therefore, it is recommended to adapt a dust collector with a nozzle for a vacuum cleaner to the casing of the angle grinder.
How to make a homemade dust collector
The simplest dust collector for angle grinders can be made from plastic bottle from engine oil.
The nozzle is made as follows.
After these simple steps, you can use the grinder to process materials, the cutting of which creates a lot of dust.
An electric file, also known as a belt grinder, is a very handy thing when sharpening, grinding and other types of processing. Belt grinders are especially popular with craftsmen who make knives. With it, it is very convenient and quick to grind the blade, and bringing out even bevels and sharpening the knife to the state of the blade is not a problem at all.
Today we will look at how to make a simple belt grinder from a grinder. This machine has a not very wide sanding belt, but is intended mainly for manual work. However, no one forbids you to fix it and use it as a stationary one.
Tools for the manufacture of such a nozzle can be used different. The author used a fairly professional set of tools - a lathe plus a drilling machine. However, you can do without them if you are smart.
The lathe will be needed in the manufacture of the leading "pulley", which transmits the movement to the sanding belt. It is made from wood. You can simply clamp the workpiece into a drill chuck or mount it on a grinder shaft.
As for the drilling machine, it’s more difficult here, the author uses it to make a mounting bracket, and also cuts the drive wheel out of wood.
Materials and tools used by the author for homemade:
List of materials:
- thick steel plate;
- three bearings;
- steel axle;
- steel plate;
- steel tubes (one must go into the other);
- spring (for belt tension);
- plywood;
- screws;
- long nut (threaded as on the grinder shaft);
- dye;
- epoxy adhesive.
List of tools:
- Bulgarian;
- mitral saw;
- pliers;
- ;
- ;
- tap;
- ;
- rasp;
- sandpaper;
- lathe;
- vice.
Device manufacturing process:
Step one. Making a mounting bracket
One of the most difficult tasks in this matter is the mounting bracket that holds the entire structure on the grinder. It is installed instead of the front handle of the grinder. However, if you have all essential tool, then there is nothing complicated in this. You can go the easy route when making this bracket. For example, it can be made from an ordinary steel plate, bent to size, and then another plate can be welded to it to fasten all structures. In general, there are a lot of solutions, let's consider how the author did it.
The author took a thick steel plate and drilling machine drilled a hole in diameter such as the front of the grinder, to which the handle is attached.
Then, with the help of a mitral saw, he made a cut to this circle, so that later the part could be pulled together on a grinder with a screw.
We take a grinder and grind off everything superfluous from the bracket. We cut off the rough edges, then just grind. There is nothing difficult in this, but it takes time.
Again we turn to the help of a drilling machine and drill a hole for the tightening bolt. After that, we clamp the workpiece in a vise and cut the thread for the bolt with a tap. In principle, you can simply drill a through hole, and then tighten it with a bolt and nut.
Step two. Making a driving wheel
The drive wheel is made of plywood, if it is not thick enough, pieces can be used. Cut the required number of rounds on a drilling machine, and then glue and tighten with screws on both sides to be sure.
We clamp the wheel in a vise and, using a rasp of suitable thickness, we grind out a pentagon. This is done so that the nut can go inside, the thread on the nut must be such that it can be screwed to the grinder shaft.
Prepare the nut. Make grooves on it over the entire area, for this you can use a grinder, but the author uses a file. It is also desirable to treat the surface with coarse sandpaper. This is all done for good bonding.
Dilute epoxy resin with hardener, grease the nut and carefully press it into the wheel. Wait for the glue to dry.
Now you can move on to grinding the wheel. Clamp in lathe bolt, and we wind the wheel on it. We turn on the machine and form the wheel profile. It should be larger in the center than at the edges. Thanks to this condition, the grinding belt does not fly off the fixture during operation. Finish off with sandpaper.
Step three. nose axle
In the bow of the device there is also a wheel, that is, a driven wheel. It is made up of three bearings. Under them you need to find the axis. To fix the whole thing, we take a plate and drill two holes in it with a slightly smaller diameter than the selected axis. The point is to then press these plates onto the axle. Cut out two parts from the plate and grind them as the author did.
Press the plates onto the axle using a vise. Now you just have to weld another plate on top of them. Plates are also welded to the axis on both sides for reliability.
Next, weld a piece of pipe to this part, it should be slightly smaller in diameter than the main frame pipe. That is, one pipe must go into another.
Step four. Work plane
A piece of pipe is used as a "frame". Weld a metal plate to it. You will rely on it when working with a tool.
Step five. Extension of the retractable pipe
Cut two pieces from the retractable pipe. Unbend one piece and drown the pipe with it. This support will be needed for the spring. We will need the second piece for the final assembly of the structure.
Step six. Arrangement of the tension system
One pipe goes into another, and between them there is a spring, which pulls the grinding belt. So, so that the retractable pipe does not twist, it is necessary to cut a rectangular hole in it. First, drill a series of holes with a drill, and then cut out a rectangle with a dremel or grinder.
Drill a hole for the bolt in the main pipe. We take a bolt with a nut and then carefully weld the nut opposite the hole. Now, when you tighten the bolt, it will hold the inner tube.
Step seven. final assembly
Now everything can be put together. Take the previously cut piece of pipe and use it to connect the bracket to the main structure. Weld well, everything should be reliable.
