When arranging a home in areas that do not have central water supply, sooner or later, but you will have to decide on the regular supply of water to the house. Even if you use large reservoirs to store water, they will need to be constantly replenished, and this is unlikely to make your life more comfortable.

There is a way out in this situation - this is the creation of an autonomous water source on your site. Such a source can be a well or a well. Both hydraulic structure has a number of its advantages and disadvantages.

Drilling wells is not an easy task, but the volume of excavation work is incomparably less than when digging a well. And, of course, the owners of the plot with the house are concerned about the question: is it possible to drill a well on their own. After all, the work of specialists is not cheap and the conditions on the site do not always allow special equipment to enter there.

If the aquifer lies at a depth of no more than 20 meters and the soil is soft, then work on drilling a well can be done independently.

Drill device for wells

To drill a well, you need to have the main tool for this - a drill. Of course, the drill can be purchased at specialized points of sale, or you can make it yourself. To do this, you need to know its design and basic characteristics.

Based on the foregoing, the use of a hand drill is assumed. Its main element is a drill pipe.

  • Drill pipe- is a metal hollow structure, which must be able to increase in length as it goes deeper into the soil. The increase in the length of the drill pipe is carried out by attaching additional sections. For the manufacture of drill pipe, it is best to use thick-walled metal pipes with a diameter of 40 to 80 mm and a wall thickness of 2-6 mm. Pipe segments are made in lengths from 80 to 150 cm (depending on the height for ease of use). The connection of the drill pipe sections while increasing its length occurs by means of a coupling or sleeve.

  • Coupling - is a short thick-walled pipe, slightly larger in diameter than the main rod, with a threaded inside (or without such thread) and one end welded to each section. The connection is secured with a cotter pin or bolt and nut.
  • Sleeve - is a short, thick-walled pipe, slightly smaller in diameter than the main rod, with an externally cut thread (or without it) and one end welded to each section. The connection is secured with a cotter pin or bolt and nut.

The drill pipe must have a handle at the top end .

  • Lever is a horizontal bar designed to rotate the drill around a vertical axis. It is made from a pipe with a diameter of 40-60 mm or other suitable material, which has a large margin of safety. The handle is welded to one of the drill pipe sections or connected to it in any other way (for example, inserted into a hole in the pipe). The length of the handle is selected depending on the convenience of use, for example, for two people to rotate the drill, it can be from 1.5 to 2 m in size.In addition, the length of the handle can be extended different ways... For ease of use, rubber tips can be used at the ends of the handle, or tips made of other suitable material.

At the end of the lower part of the drill pipe, a cutting part of the structure is attached, called a drill, a knife or directly - Boer.

Borax varieties

For homemade drilling devices, there are two main types of cutting attachments. This is a spiral drill and a spoon drill.

Spiral drill

The spiral drill has a second name - auger drill. It is a rod with a diameter of 40-60 mm made of strong metal with a pointed end and two knives made of sheet metal(discs sawn in half) with a thickness of 1.5-4 mm, located at an angle of 20 degrees to the axis of the rod.

This type of drill can be further used for earthen garden and construction works small penetration depth.

Spoon drill

A spoon-type drill or a spoon-drill is used for drilling deeper wells than a spiral drill, up to 15-20 m deep. It is a metal cylinder made of a thick-walled pipe. The length of the cylinder ranges from 60 to 100 cm with a vertical (sometimes spiral) slit. The pipe diameter is equal to the diameter of the well and is selected for placement in the well necessary equipment... The cutout in the cylinder is required to remove soil from the sidewalls of the well. In the lower part of the cylinder, a thick drill with a diameter of 16-32 mm or a narrow steel plate 10-15 cm long is welded to give and maintain the direction of drilling. The drill cylinder is located on a vertical rod offset from its axis by 10-15 mm. The offset is designed to make the borehole larger than the drill itself. This eccentricity allows the spoon drill to be propelled inside casing and carry out their installation already in the process of drilling, which, in turn, protects the walls of the well from destruction.

What is needed for work

First of all, to make a drill with your own hands, you will need welding skills and the ability to weld metal parts with high quality that work under high load conditions.

To make your own drill, prepare the following materials and tools:

  • metal pipes of the required diameters for drill pipe, couplings, bushings and handles (or finished couplings and bushings);
  • a metal cylinder and a drill or pointed plate for a spoon drill;
  • steel rod of the required length for the bit tip;
  • steel plate (sheet steel 2-4 mm) or finished disc (circular saw blade) for a spiral drill;
  • bolts, nuts, pin for cotter pins;
  • welding machine;
  • vice;
  • grinder and various-purpose discs 150 and 180 mm;
  • if necessary, a threading tool;
  • rasp;
  • electric drill;
  • wrenches, hammer, screwdrivers and pliers;
  • tape measure and marker;
  • protective and welding goggles, gloves and overalls.

Making a drill with your own hands

To make a drill, of any type, you first need to perform the following general steps:

  1. To make drill pipe segments using a grinder, cut the pipe into segments 80-150 mm long.
  2. To manufacture couplings or bushings, cut the pipe of the appropriate diameter into the required lengths.
  3. Using a special tool, cut threads on workpieces for couplings or bushings.
  4. Use an electric drill to drill holes in couplings, bushings and segments for cotter pins or bolts.
  5. Cut the steel rod into pieces large enough to use as cotter pins.
  6. Bend one side of the cotter pin in a vice by 90 °, in the other, drill a hole for the retainer.
  7. Weld (or otherwise attach) a coupler or bushing to one end of each drill pipe segment.
  8. Make a drill handle of the required length from pipe or other prepared material.
  9. Weld the handle to one of the drill pipe segments (or drill a hole in it to insert the handle) or attach it in any other way.

Making a spiral drill

To make a spiral drill, follow these steps:

  • Take one of the drill pipe segments and weld to the bottom of it (opposite to the socket), or otherwise attach a pointed tip made of strong steel. If a steel rod was provided for this drill element, then sharpen it.

  • Cut out round plates from sheet steel for making a drill knives (or take a ready-made disc from a circular saw).
  • Grind the cut points of the round plates using a rasp or special electric drill discs.
  • Saw round metal plates or a circular saw blade into two equal parts (in half).

  • Sand the edges of the slices.
  • On the arcuate side of each plate, using a rasp and grinder, sharpen an even or serrated sharpening (this is not required for knives made from a circular saw blade).
  • Weld the discs to the rod (pipe), opposite each other, stepping back 120-200 mm from the tip of the drill bit. The angle between the plane of the knives and the horizontal plane should be - 20 °, between the knives 30-40 °, and the angle of inclination to the axis of the rod (pipe) should be 70 °.

Making a spoon drill

To make a spoon drill, follow these steps:

  1. Cut a longitudinal slot in a cylinder from a thick-walled pipe (make a cut). The more loose the soil in which it is supposed to be drilled, the smaller the width of the cut.
  2. Use a hammer to cut the edges to the desired section.
  3. Sharpen, using a rasp or grinder, the bottom and side cutting edges.
  4. Weld a sharpened plate or a prepared metal drill to the bottom of the drill.
  5. Weld a rod (drill pipe section) to the top of the drill with an offset of 10-15 mm from the axis.

The design of the drill, after manufacture, must be tested in practice and eliminated the identified deficiencies. Then it can be painted to give a more aesthetic appearance and protect against corrosion.

Provide constant access to drinking water in an area where there is no centralized water supply, you can in a simple way- drilling a well for water. You can perform work and prepare a tool for this on your own, if you know the features of the technology.

Is it worth drilling a well with a hand drill?

Before purchasing materials and starting work, it is worth deciding which equipment and drilling method will be the most effective and optimal, taking into account all important factors. Also, it is necessary Hand drill is a great solution.

If you have to work in soft soils and the depth of the proposed hole is no more than 20 meters.

The advantages of this solution also include:

  1. Cheapness. Thanks to this choice, you do not have to pay drillers for labor and, moreover, buy / rent rather expensive electrical equipment.
  2. Autonomy. The handheld device works on a mechanical basis, so you do not have to interrupt the process due to power outages, for example.
  3. Versatility. The hand drill is used not only for arranging a well, but also in many other areas of agricultural activity. For example, when building fences, planting cultivated plants, arrangement pile foundations and many other types of gardening, repair and restoration and construction work.

But this device also has certain disadvantages. In addition to the limitations regarding the working environment, there is such a disadvantage as the timing of work: a hand drill works slower than an electric counterpart, and therefore is less efficient. In addition, you must have sufficient physical strength to use it. But if you can handle it, then it will not be difficult for you.

Hand drill design

If you have weighed all the pros and cons and still come to the conclusion that hand drilling is your choice, then you should first familiarize yourself with the design of a hand drill. It consists of:

  • pens;
  • inserts;
  • cutting nozzle;
  • couplings;
  • bolts and nuts;
  • cutting plate;
  • guide rod;
  • blades.

How to make a drill yourself?

For an experienced, prudent owner, who is used to doing everything with his own hands, so as not to doubt the quality, making a hand drill will not be a big problem.

Required details and inventory

To make a drill you will need:

  • welding device;
  • welding clamps;
  • grinder with a cutting disc for iron;
  • electric drill;
  • a pair of gas keys;
  • a die, the diameter of which should be equal to the diameter of the rod;
  • die holder;
  • vice.

Algorithm of actions

Before you start directly making a drill, you can take care of its greater efficiency and make looseners, with the help of which the drill will simply rake out the already loose soil, which will greatly simplify and speed up the drilling process. You can make such a device from an automobile spring. The cutting edge should be sharpened to further simplify the work.

After that, you can start cutting threads. First, clamp the bar upside down in a strong vise, and it is important that an angle of 90 degrees is observed. Pay attention to the protrusion of the bar - it should not exceed 10 cm in any way, so that unnecessary shock absorption does not occur when the die is subjected to an onslaught. Then file the end so that you end up with a cone.

After that, you can start cutting directly. The die holder rotates clockwise at low speed. If the die is stuck, simply twist it and gently file away the interfering burr. After that, again you need to screw the die onto the finished thread section and continue cutting work to the planned level.

The optimum thread length is 10 cm.

The cylinder itself is made of sheet steel, and the spiral must be rolled up strictly according to a given diameter (as a material, it is excellent old will do piece of pipe). The next step is to screw on the sleeve, which is welded onto the base bar in the area of ​​the butting seam. This completes the main work. It remains only to secure the handle.

Features of the manufacture of a spoon-shaped drill

The spoon auger is especially good for work in shatter-resistant soils. This is a great solution for those looking for a larger hole than a conventional device can do. How is this possible?

This device is a conventional drill inside a steel cylinder, which prevents the drill from getting too a large number ground and clogging. To make a really high-quality device, you need to take into account the main factors:

  1. The extracted soil remains inside the cylinder due to compression and adhesion. Therefore, the more free-flowing the soil is, the narrower the slot should be made in the lateral surface of the cylinder.
  2. The length of the device should be approximately 700 mm.
Process hand drilling not complicated and very practical.

Making a drill is not a big problem, and if done correctly, you can finish drilling work fairly quickly and save money on staff and electricity. - a separate topic requiring special attention.

Excavation works accompany almost all types of construction. Each building stands on the ground, and the foundation is generally in the depths of the earth. Thanks to this arrangement, the building is able to reliably stand and maintain its integrity for more than a dozen years.

Excavation work is carried out using various tools such as special heavy equipment, motorized hand tools and devices and actually completely hand tools... One of the hand tools is the simplest earth drill.

Screw drill

Let's start with DIY assembly of the simplest and most popular screw drill to use. Due to its rather simple and affordable design, it is very convenient and practical, and it is incredibly easy and quick to drill the ground with it. Besides simple form allows you to easily and without any problems make one at home with the most scanty material costs.

Drawing of a spiral drill for a well

In the factory, such drills are a tube that plays the role of a central pore and connects the driving element, the handle, with the working part, the screw. The screw is made of plates of different diameters, each of which is sharpened on one edge. The shape of the plates is made in a semicircle, and they are also slightly curved.

The working plates are made of special steel for tools, which has a very high strength, shock and wear resistance. At home, of course, you cannot find such materials, but you can get a simpler model without problems, for that you should get a welding and some locksmith tools.

At the heart of our drill will be a pipe with a large wall thickness, so that it does not deform or burst at all during operation. A sharp tip is welded to its end, which will act as a guide cone, due to which the drill will work in a strictly established direction.


The next step will be the manufacture and installation of the working part with your own hands, namely, cutting knives for drilling. They should be made of steel with a thickness of three millimeters, less will not be enough and they will break or deform very quickly during operation.

An excellent option would be to use the old circle from circular saws ... It is made of metal with sufficient strength and thickness. This circle should be cut into two equal parts.

Their installation should be done, stepping back twenty centimeters from the lowest point of the edge of the guide. It is necessary to weld the blades at an angle of fifteen to twenty degrees relative to the plane of the ground, thus, an angle of about thirty degrees will be obtained between the plates.

The handle will be made of any pipe similar to the base. It is simply welded or screwed onto the top of the base. A removable handle is needed when you make a drill with your own hands with the ability to increase its length in order to be able to drill deep holes.

Spoon drill

This type of drill is one of the simplest and most affordable today. Due to its simplicity of design and good functionality, it is widely used for drilling various soils. Perfect for drilling wells in light and loose soils. Manufacturing will take place from a simple pipe, about seventy or eighty centimeters long, this size will be quite enough.

Bur-spoon (spoon drill) - a metal cylinder with a spiral or longitudinal thread.

We cut the lower part by seven to eight millimeters so that we can bend the edge that will be cutting. The size of this cut should be selected based on what kind of soil you plan to drill with this tool. For heavier and knocked down soils, it should be increased, but if drilling will take place in loose sandy soils, then the slot should be narrowed.

The lower part should be bent with your own hands so that it forms a bucket-like shape, and the cutting edges, which are located in the reverse direction, should be sharpened with high quality so that they can easily cut into the ground and can easily cut the roots that get in the way.

To improve the quality of drilling, a drill can be welded between the bent buckets, which, as in the previous version, will serve as a guide and facilitate the work of the drill.

In this case, the direction of penetration of the drill must coincide with the direction of the drilling buckets, otherwise there will be no benefit from it. We weld the handle or screw it in according to the same principle as in the previous version, using the most common pipe.

If you need a hole with a larger diameter, then you should select drawings with a larger pipe. The borehole diameter will be outer diameter matched pipe, so select it according to your requirements. It is best to do several options at once with different sizes so that you always have a choice.

Hammered view

Working with such a drill, in comparison with the previous varieties, is the slowest and entails large labor costs. But this type of drilling tools is great for creating wells in loose and sandy soils. The main working body of such a device is the so-called driven glass.

Diagram of a bailer with a ball valve.

The manufacture of such a component comes from a thick-walled pipe, from one to three meters long. Such a pipe will be driven into the ground, and its entire cavity will be filled with soil, in which the well is drilled. A longitudinal slot is cut in the pipe, through which all the soil collected inside will pour out. On the upper part the bar is welded on.

If you want to drill watery or sandy soils do it yourself, then set on the lower edge special valve, which is called a bailer. When clogged, it is in the open state, and in the case when the pipe starts to be removed, it immediately closes, thereby blocking the soil collected inside, preventing it from getting enough sleep.

Is it worth making a homemade drill at all

Of course, if you have free time and you often need the help of a drill on the farm, or you plan to start construction, then you should definitely make such a tool with your own hands.

If you compare the cost of a home-made tool and the price of a purchased tool, you will notice that a home-made one will cost you ten times cheaper, while it can last a very long time and will help to cope with various difficulties during earthworks.

In addition, having spent the floor for, you get a fairly high-quality and useful household tool that will always be at your fingertips and, if necessary, will help you cope with the task.

You will not need to run around your neighbors and ask who has this tool or run to the store and spend a lot of money to buy it.

Drilling shallow wells in soft soils can be done with homemade device... The maximum possible depth of the wellbore in this case can be 20 meters. One of component parts the structure is a split drill pipe, the length of which increases with the deepening of the well. Another important element a handle is considered that allows one person or two with an assistant to rotate the pipe manually with the use of physical effort. The main element hand tool of course is a drill, which can be made in several ways. But if you decide to make a drill for a well with your own hands, then it must be made of metal, so the master must have welding equipment and the skills to work with it.

This video shows how to make a drill for a well in a couple of hours. Judging by the reviews, the advice of the author of the video helped many novice DIY masters in practice.

Self-made spiral drill

In the very simple version The spiral drill is manufactured in the form of a metal rod with a well-pointed end. A pair of knives are welded 200 mm from the tip of the tip. For the manufacture of knives, halves are taken steel disc, 100-150 mm thick. Welding knives to a metal rod is carried out at a slight angle, the value of which is no more than 20 degrees to the horizontal. In this case, the halves of the steel disc should be located opposite each other. As a result, the angle between the welded knives is 40 degrees.

The lower edges of the cutting elements of the hand-held drill bit also sharpen well. The speed and ease of cutting the tool into the ground depends on how sharp the knives are.

A factory-made spiral drill is made from special tool steel, which is heated, and then twisted into a spiral and hardened

Industrial Drill Models of this type are made in the factory from a strip of tool steel, heated and twisted into a spiral. The pitch of the spiral turns is equal to their diameter. After tightening, the steel is hardened.

How to work with a spiral drill?

Homemade tool during rotary motion, produced by the worker with the handle, is cut through the sharpened knives into the soil layer. Then the hand drill for wells is pulled up along with the cut soil. The earth spills out to the side of the drilling site. The operation is repeated again.

Cleansing a homemade spiral drill from the soil raised from the wellbore upward is carried out near the work site and is removed from the site on a trolley

With an increase in the depth of the structure, the tool bar is built up. In this case, the constituent elements are fixed to each other using threaded or sleeve-type connections. To insure against the separation of the component parts of the rod, their connections are additionally fixed with cotter pins.

By lifting the elongated tool up, the additional rod links are removed. The spiral drill copes well with clayey soils, as well as fine gravel that comes across on its way into the depth of the mine.

Features of the spoon-type drill device

In soils resistant to shattering (loam, wet sand, etc.), it is more convenient to use borax spoons. A homemade spoon drill for wells is made in the form of a cylinder, in the lateral surface of which a longitudinal slot is made. Sometimes the shape of this slot takes on a spiral shape. The length of the bore-spoon is usually no more than 700 mm. The extracted rock is held in the cylinder cavity due to its compression and adhesion. The more loose the soil, the narrower the cut in the tool should be. To obtain a cylinder, you can take sheet steel and roll it to a given diameter. The easiest way is to choose a piece of pipe that is suitable for the size, initially having a cylindrical shape.

A homemade hand-made drill spoon is made from a piece of pipe of a suitable section, in the lateral surface of which a longitudinal or spiral slot is made for excavating soil from the side walls of the well

The bur-spoon excavates soil not only with its horizontally located lower edges, but also with its vertical edge. In this case, the soil accumulates in the cavity of the cylinder. In some cases, it is welded to the bottom of the structure conventional drill on metal, which must be positioned strictly along the axis of the rod.

The main feature of the drill-spoon lies in the fact that the axes of the drill and the rod coincide, while the axis line of the hand drill body, together with the cutting longitudinal edge, is shifted by a millimeter and a half relative to the central centerline. Thanks to this mutual disposition axes, the tool manages to drill a hole with a larger diameter than the drill itself. This is possible by removing soil from the side walls of the shaft with a longitudinal cutting edge. To clean the tool from the excavated soil, the drill is periodically lifted up.

It is important to note that the spoon drill goes smoothly inside the casing, which is installed in order to prevent the collapse of the well shaft.

Should I do manual drilling at all?

The advantages of the manual method of drilling wells include:

  • low cost of work;
  • the ability to operate the hand pump during power outages;
  • preservation of the landscape of the site, because the arrival of special equipment is not provided.

The disadvantages include the existing restrictions on the possible depth of the structure. In addition, the operation of a homemade drill is almost impossible in dense soils.

Homemade drills for drilling wells can also be used in the construction of fences, planting plants, pile foundations and many other types of gardening and construction work. As you can see, building such a good "helper" is within the power of any artisan who is accustomed to using homemade tools in the household.

Not always on summer cottage or country house for water supply, it is rational to build an expensive one. Plots used only for vegetable gardens and picnic areas in the summer months are usually equipped with surface-type wells, because this does not require special permits, technical conditions and development of a technical passport. In addition, a drill for such purposes can be made and assembled by yourself.

Features of hand drilling

Favorable conditions for drilling a well by hand are:

  • groundwater at a depth of up to 20 m;
  • soil without hard rocks that make manual drilling difficult.

Manual drilling of a well can be done in two ways:

  • rotational;
  • rope-percussion.

The meaning of the rope-impact method is to build a well, a heavy pipe with a sharp end, tied with a rope to the frame, is thrown into it from a relatively high height. The soil is separated from the blows by this structure, and gets inside it. Then the pipe rises to the surface with a winch and is freed from the accumulated rock. This is how the deepening occurs. The advantage percussion drilling is that it can involve one person.

Rotary drilling is performed with a tool capable of cutting into the ground by rotating and lifting the soil to the surface. This drilling method requires two people to rotate the drill rod using a rebar or pipe. As the drill structure deepens into the ground, it is built up with additional split tubes.

Upon completion of drilling operations, the casing is lowered into the well.

Boer variety

Spiral drill Is a tool for drilling by cutting into the ground with special cutting plates welded to the tool shaft.

In addition to the drill itself, in order to build a well, you need: a holder and additional detachable tubes to build up the required length of the structure.

Drill or drill bit Is a massive instrument consisting of a pipe with a bailer placed on the bottom. It can only be used if there is a tripod that provides a lifting height of the drill of 2–2.5 m.

Boer spoon- a device with which rotary drilling is carried out, as in the case of using a screw tool, only it is equipped with a large metal cylinder at the end of the rod. This design provides an effective accumulation of highly loose or wet soils, which are poorly handled by a conventional auger drill. It is completed with a holder and additional detachable tubes for adjusting the length of the tool.

How to make a rope percussion drill

The hammer drill mechanism is quite simple in design. To make and assemble it, you will need the following material resources and equipment: thick-walled pipe of the required dimensions, corners, Sheet steel, tape measure, grinder, welding machine and manual or automatic winch. To make and assemble a percussion drill, you must perform some steps in the following sequence:

  • A tripod is assembled with a height of no lower than 2 meters.
  • The top of the tripod is equipped with a special assembly that allows the installation of a manual or automatic winch.
  • A percussion instrument is made.

This requires a pipe with an outer diameter that corresponds to the diameter of the future well. A piece of heavy plate is welded onto one end. Then a hole is made in it in order to fix the cable. And at the shock end of the pipe, sharpenings are made around the entire circumference. To ensure the strength of these elements, they need to be hardened. And also the tool should be equipped with additional weights.

The base is being prepared for placing the working tool. A shallow hole is cut in the ground. Then a drill for wireline drilling It is mounted on a tripod and is positioned so that it can completely immerse itself in the prepared area under the influence of its own weight.

How to make a spiral drill?

To independently make a spiral drill at home, you will need the following tools, equipment and materials:

  • welder;
  • yardstick;
  • Bulgarian;
  • steel bar with a diameter of 25 mm of the required length as a future bar;
  • pipe with a diameter of 25–32 mm;
  • steel blades (you can use a cut saw blade from a circular plate of the required size).

Procedure to be followed when self-made screw drill:

  • It is necessary to saw the steel disc into two semicircles.
  • Both parts of the former disc need to be sharpened well.
  • A steel bar with a diameter of 25 mm must also be sharpened on one side.
  • From sharpening, at a distance of 20-25 cm, you need to leave a mark in the form of a notch.
  • To the marked place on the bar, semicircles from a steel disc should be welded at an angle of 20 degrees.
  • The total angle between the semicircular blades should be 40 degrees.

It is better to entrust sharpening to a professional or a person who knows how to sharpen tools. Because the quality of the sharpening determines how the future tool will cut into the ground, and therefore the speed of drilling a well.

Hypothetically, an auger drill can be made using a steel spiral for this. To do this, you need to get a strip of tool steel, heat it up to a temperature at which it can be bent into a spiral with the required pitch and corresponding diameter. Next, harden the spiral, and only then weld it to the bar. However, at home, it is almost impossible to perform these actions efficiently.

Materials for making a drill

The bur-spoon is made from materials that can always be found on the site. Even an unnecessary car will do. gas bottle with a diameter of 22 cm.To work, you will need tools and materials such as:

  • steel pipe of the required diameter;
  • gas cylinder with a diameter of 22 cm;
  • angle steel;
  • corner Sander or grinder;
  • electric welding machine;
  • yardstick.

How to make a bur-spoon

The procedure for making a spoon drill:

  • From the cylinder it is necessary to cut off a part 25 cm long with a grinder.
  • At the end of the cut off section, you need to make cuts that will be used as cutting edges.
  • Cut openings from which the soil will be removed, which has fallen into the cylinder during drilling, the size should be 50 * 200 mm.
  • A steel pipe is quite suitable for attaching the future handle.
  • IN opposite side from the cutting end of the cylinder, it is necessary to make a hole for the pipe to be welded.
  • It is possible to strengthen this structure by welding jumpers made from the same pipe to it.
  • The cutting edges of the drill must be bent outward.
  • You will need a piece of steel corner, on one side of which cuts are made up to 4 cm in size and a width equal to the thickness of the cylinder wall.
  • A drill is made of strip metal 200 * 35 * 3 mm.
  • The strip is clamped in a vice and bent into a spiral. The bottom of the spiral is trimmed at a 45 degree angle and sharpened.
  • The manufactured drill is welded to the drill.
  • Making a handle for a drill.

A piece of reinforcement with a diameter of at least 1 mm and a length of 50 cm is cut off.In the pipe on which a homemade drill is fixed, holes are drilled every half a meter with a diameter of 11 mm with an indent from the upper edge equal to 15 cm. holes to rotate the drill.

When you need a long drill rod length, you can do one of these methods.

Use threaded couplings:

  • for this, an external thread is made on each pipe segment;
  • then threaded couplings are made in the required quantity;
  • to insure against spontaneous separation of parts, a cotter pin is made.

Using welded bolts and nuts welded to the ends of the sections. This method is applicable for split pipes of small diameters. But this method is not the most reliable due to the fragility of the welded joint.

Use pre-fabricated bolt-on boom sections. This is a simple and efficient way:

  • couplings are cut from a pipe with a larger diameter than that of a split pipe;
  • then they are welded to the end of one pipe, and the other free pipe is inserted into the sleeve:
  • each such connection is fixed transversely with an inserted bolt and nut.

One piece and long drill pipe will make the job much more difficult.

The best solution is a split design with an optimal section length of 0.8 to 1.2 m.

Thanks to such a device, it will be easier to select the required length of the drill pipe and increase it as needed.

Some useful tips that facilitate drilling a well using a hand-made homemade drill:

  • you can use a homemade bailer to optimize the process of dredging to the surface, since it is better to collect the rock in a container;
  • if it is difficult to raise the soil to the surface, then you need to build a lever from improvised barrels or logs;
  • a homemade drill is also useful for other household tasks.

This tool can be used to dig holes for fence posts or pile foundations.
