Is it possible to make a drill with your own hands? For some earthworks In the countryside, an indispensable tool is a hand drill. A hole dug using this tool will be compact, and the excavated earth will be less than when working with a shovel. The hole drill will also preserve the natural structure and density of the soil.

Types of garden drills

Garden augers vary in power, size and purpose. The following types of hole drills are distinguished:

• non-motorized (a hand-held device that is actively used in everyday life);
• mechanized (a manual device that runs on gasoline and a motor);
• mounted (a mechanized device that works with a tractor or other equipment).

A non-motorized hole drill will be able to make holes of medium diameter and depth in the ground. The work is carried out thanks to the operator who holds the tool. This device is very convenient to use and easy to transport due to its compactness. Using such a tool, you can put up a wooden fence or dig holes for seedlings. The device consists of a main rod with a knife and a T-shaped handle. There are models of earth drills with removable knives or a screw, which makes it possible to drill holes various sizes(up to 2 m) and diameters (up to 30 cm).

The mechanized drill is equipped with a drive. Him simple design: screw auger or rod and electric or gasoline drive with geared motor. The screw is started thanks to the rotational and translational movements of gears. Such a tool can drill deeper holes (up to 3 m).

Mounted drills are intended for drilling wells big size and diameter. They are used for the installation of street lighting poles, fencing of enterprises, train stations, and airports. Thanks to them, fencing for trenches is made. They have great performance and power.

To choose the right device, you need to pay attention to specifications drill: hole diameter, depth, number of holes per day, power.

Making a drill yourself

Making a pit drill is labor-intensive work, but it does not require any special skills. To make an earth drill you will need the following tools:

• cutter;
• rod (a metal structure that increases when the drill is immersed in the soil);
• handle for rotating the device;
• welding machine;
• lathe;
• motor with sandpaper;
• electric drill with various drill bits for metal;
• steel sheets;
• steel rods;
• pipe.

To make a drill with your own hands, you can use the drawings. First you need to cut a sheet of steel and cut out circles different diameters, which will ensure the versatility of the device. Circles will be used to make the cutters. The diameter of the workpieces should be larger the right size recesses by 5 mm. All workpieces are drilled in the center so that the holes are slightly larger than the diameter of the rod.

On a lathe, bushings are made from steel with perforations in the center, in which the threads are made. They will be needed to attach the cutting parts to the rod. It is recommended that they be performed by a master, because the reliability of the device itself will depend on its strength.

Next, you need to turn the round blanks into spiral ones. For this purpose, a small segment should be cut out of the workpiece, the ends should be secured in a vice and stretched. Due to stretching, the workpiece takes the form of a spiral. There is no need to stretch it too much, otherwise the metal will lose strength.

After this, sharpen the outer end of the spiral so that it cuts the soil easier. Small cuts (approximately 3 mm) should be made on the rod at intervals of approximately 8 cm from the edge. Sharpen the edge of the rod for easy penetration into the soil and cut into a shallow spiral. To make it easier to work with dense soil, weld a metal drill to the edge of the rod.

The rod is made from pipe sections. The possibility of fastening them to each other is provided. A handle is attached to the top to rotate the device. Upon completion of all construction work, you need to paint the device with a special paint that can protect the instrument from corrosion. The drill for poles with your own hands is ready.

Every dacha owner at least once in his life had to dig a hole on his territory for the purpose of building some kind of object. This could be an arch, a support, a pillar, any element of the exterior or a full-fledged building, for example. Often, the construction of such things requires wells or holes, which are not always easy to make due to their inconvenient location. Also, work can be complicated due to difficult soils. IN similar situations the usual shovel remains not the most convenient tool for digging a deep hole, and therefore private owners often have to hire a specialist with a drill.

The garden hand auger has been and remains one of the most useful devices for dacha owners. The tool is distinguished by its compact dimensions and low weight, which makes it very convenient to use and transport. Crafted from hard metals with your own hands, the post auger is capable of going through plant roots and small rocks in the ground. The drilling process is carried out due to rotational movements at the desired point.

Design

The main purpose of the drill is to dig wells to a depth of approximately equal to depth mortgages columnar foundation. Cutting through the soil is carried out due to the cutting part, which in turn can be performed:

• Half discs;
• In the form of screws;
• Solid or removable;
• Multi-tiered;
• Two-blade;
• Helical.

Some hand drills have small blades at the bottom with a gradually increasing radius towards the top. Nevertheless, often factory products turn out to be unusable in practice, due to a discrepancy between the diameter and the diameter of the new hole or due to the impossibility of penetration to the required depth. And although the cost of a factory model is small, it makes sense to learn how to make a drill with your own hands. Technology self-assembly It is cheap and simple, the main thing is to accurately determine the configuration of the future instrument! To do this, it is necessary to distinguish between the designs and functionality of the models:

• Shaper plow . Covers the lower extended area of ​​the socket. In most cases, the tool is used to strengthen columnar foundations during the construction of large structures.

The handle with the screw part is fixed due to bolted connection. The total length of the finished drill is usually a little more than one meter. This allows you to easily make holes up to 700 millimeters deep. If it is necessary to make a hole of greater depth, the structure is supplemented with a special connecting tube half a meter long. The complementary element resembles a part with a nut and bolt at the end sections of the pipe.

• Ground receiver . The soil is accumulated in a special storage facility. The drill is in most cases used when drilling holes from 35 centimeters in diameter.
• Baking powder . The tool is made in the form of a screw or two inclined blades. In the first case, a knife in the form of a spiral is placed on a bar.

DIY drill

If you want to make a manual pole drill yourself, as a rule, there are no difficulties during the assembly process. However, to work you will need following materials, parts and tools.

Materials

To ensure the product has the required level of strength, as well as to be able to perform work in hard ground conditions, it is worth using iron pipes with wall thickness not less than 3.5 millimeters. You can make cutting discs either with your own hands or take ready-made ones from circular saw. In the first case, it is recommended to take metal sheets thickness from 3 millimeters.

Details

Parts you will need:

• 3 pipes: one 400 mm long, two 500 mm long. The outer diameter of the pipes should be 40 mm, the wall thickness should be at least 3.5 mm;
• M20 nut and bolt;
• Drill with a diameter of 20 millimeters with a tip;
• A pair of disks of 150 and 100 mm in diameter.

Tools

• For cutting elements, a sharpening wheel;
• Grinder and hammer;
• Electric drill paired with metal drills;
• Welding machine;
• Locksmith kit.

If you do not have a drill tip, you can replace it with a regular drill bit with a tapered shank. In this case, the diameter of the element must fit the screw part. To avoid injury when making your own, it is recommended to use soft bicycle handles.

Work order

• First of all, the center and radius of the circle, which will act as the future blade, is marked on a piece of metal. The intended workpiece is cut out using a grinder. After this, cutting and cutting lines corresponding to the size of the collar circumference are drawn along the diameter line. The finished disk is divided into two parts. The holes for the collars are made with a grinder;
• Using a grinder, four 3-4 cm longitudinal cuts are made at the end of the pipe blank intended for making the wrench. Using a hammer, the cuts are collected in the center, thus forming the tip of the pipe. To avoid filling the inside with soil the tip is processed by welding;
• The halves of the disk with the knob are welded so that the angle to the plane of rotation is about 20 degrees, and the distance between them remains at least 5 centimeters;
• The extension pipe is welded like the letter “T”, strictly perpendicular, it is strengthened by a metal “kerchief”. The workpiece is placed inside the collar pipe, after which a through hole is made, which will allow the elements to be fixed with wings and a pin;

In the extension cord itself hand drill It is worth making several holes at once - due to them, in the future it will be possible to change the length of the knob without any problems.

• Finally, all that remains is to sharpen the blades. In this case, the cutting edge of the cutters is processed in such a way that when rotating, the tip “looks” down!

How to apply a protective layer?

The hand drill for poles is ready, but it will not last long if it is not treated with special protective composition, which will protect the tool from harmful corrosion processes! For this purpose, all surfaces are thoroughly cleaned with sandpaper, and then treated with phosphating solution and primer. At the end the drill can be painted, but this is optional.

During the excavation process, namely upon completion, the drill should be disassembled and the bolted joints should be cleaned of dust and dirt, processing them waterproof lubricant. Such prevention will ensure long-term operation of the tool, eliminating sudden jams. bolted connections.

How to increase tool productivity?

During construction work, namely when making wells, builders are often faced with a large amount of vegetation inside the soil. You can make working with a drill easier by sharply sharpened knife edges. In addition, you can also round the cutting area and cut teeth on the sloping part of each blade, which will significantly improve the ease of use of the tool.

Hand Drill Upgrade

The first improvement can be called performing a drill paired with replaceable cutters. This solution will allow you to dig holes of any diameter. In addition to spare parts, it is also important to think carefully about the method of fixing the cutters to the driver! The most simple option a connection is considered to be made by a pair of welded metal plates.

Important point! Welding should be done at an angle of 20 degrees relative to the plane of rotation.

A pair of holes are drilled into the mounting plates and blades for bolts. The cutters are secured using nuts, washers and M6 bolts. To prevent the bolts from causing additional interference during the drilling process, they are placed with the thread facing up.

Second improvement useful for builders working in areas with deep compacted soils. Thanks to a small flat cutter welded between the cutter and the lance, the hand drill will additionally perform centering and loosening of the soil while drilling. To complete this element with your own hands, you will need a pair of plates measuring 3 by 8 centimeters. In addition to the above, her presence can speed up the work process.

Third improvement method – increasing the functionality of the lower end of the gate. This happens due to a lance: a plate measuring 2 by 10 cm is cut out of a narrow sheet of metal and sharpened with a cone point using a grinder. A machined plate is inserted into the end of the knob, which is then welded and flattened.

However, there is another way to create a peak. From sheet metal a longer plate is cut out - about 17 centimeters in length. The workpiece is heated and, like a corkscrew, is rolled into a screw. Further work is carried out similarly to the first option.

A drill will work as an auger required diameter, which can handle metal and wood. Such a drill will easily pass through layers of soil, easily reaching the required depth.

Fourth – you can also make friezes with your own hands from grinder discs, just not ordinary ones, but those designed for working with stone! The central hole is expanded to fit the dimensions of the knob, the circles are cut along the radius line. The ends of the disk are separated in different sides due to which something like a screw is obtained. At the end, all that remains is to weld the part to the drill.

A circular saw blade is also suitable for creating a cutter. Its sharp teeth can easily pass through any vegetation and roots in the thickness of the soil. Which option suits you best?.. It’s not difficult to create a hand drill for poles with your own hands, and it will take a little money. All work will take approximately several hours.

Pillar – main architectural element many types of fences and buildings. To install it, you need a special tool, a hand drill for poles. With its help, holes are selected in the ground into which the pillars are installed.

If necessary, devices large quantity holes, motorized drills are used, but in private construction, in particular, during self-construction fences are used manual options such a tool. There are a lot of industrially produced models, but nothing prevents you from making your own drill that will satisfy local needs. And it will cost less than store-bought.

At least minimal skills in working with a welding machine and its availability are required.

Alternative option– production of custom-made tools according to the selected project. In this case, you will need to find performers and a suitable drawing.

Construction of an earth drill

Fundamentally, each drill consists of three main elements:

1. Pike, which plunges into the ground first and centers the entire tool during the first stages of drilling. Some versions of auger drills and designs with an earth receiver are not equipped with a lance.
2. Cutting part, made in the form of a screw, half disks or having another configuration.
3. Solid or segmented rod, to the bottom of which the working elements are attached, and to the top - a handle or pin for connecting to a motorized unit.

The different types and combinations of these elements make the difference between drill types. The garden auger is equipped with a peak and two blades, mounted on the main rod at a certain angle (usually 35-40 degrees to the perpendicular to the axis). This is not the most productive tool used for making planting holes or holes for small supports.

Auger drill – specific option for quick installation of wells for fencing supports. It is equipped with a spiral blade with several turns for removing soil, which is cut by a blade at the bottom of the auger.

The cutting edge of the blade should always remain the lowest point of the auger. Otherwise, the device will not be able to drill into the ground. Therefore, models with two to four semicircular blades are suitable only for making shallow holes for planting plants. The soil is directly cut by only one corner of one blade.

Drill with earth receiver is a piece of pipe large diameter, in the lower inner part of which blades, most often equipped with teeth, are fixed. As the drill rotates, they fill the volume of the pipe above them, after which the tool is removed from the ground.

Drill for TISE piles is a tool of the previous type, equipped with a folding blade for creating channel extensions for pouring pile foundations. Sometimes, instead of a cutting part, the earth receiver is equipped with a blind bottom for collecting soil selected by a folding blade.

Making a drill

The main tools for self-made drills are used by an angle grinder and welding machine. The process begins with the selection and preparation of the main axis of the tool. A round (26.8-48 mm in diameter) or profile (20×20-35×35) pipe is suitable for this role.

From the profile square pipe it won't be possible to make a screw one garden auger with your own hands. For it, exclusively pipes with a round cross-section are used.

The required length is calculated by adding 50-60 cm to the depth of the future well. If the final value exceeds one and a half meters, you will need to make the bar collapsible. The connection mechanism can be any (threaded, cotter pin, or other), the main thing is that it can withstand the loads during rotation with resistance.

The pike is usually made separately. From a piece of pipe, inner diameter which is equal to the outer one, you can simply make a sharp tip or flatten the pipe, and then roll it into a spiral of one or two turns or sharpen it in the manner of the tip of a wood drill. Other options include soldering a narrow spiral screw. Good results shows the use of a forty-diameter wood drill. In this case, the diameter of the end drill must exceed outside diameter rods.

After the lance is welded to the axial rod (or its lower segment), you can begin constructing the main cutting part. To do this, an old saw blade from a circular saw, the diameter of which corresponds to the parameters required hole, cut into two equal halves. The resulting blades are welded to the main rod above the peak. The preferred angle to the perpendicular to the axis is 30-40 degrees, to the vertical - strictly 90. The cutting edges are sharpened.

Another, more productive option is to make a screw. For it, circles are cut from sheet iron, the diameter of which corresponds to the parameters of the required recess. The number of disks is equal to the number of turns future spiral(at least three). The blanks are stacked, after which a hole is drilled in their center, commensurate with the outer diameter of the pipe.

Afterwards, a small segment is cut out of the disks. The resulting parts must be welded to form a spring. Then it is stretched on a winch, the seams between the turns are welded with reverse side and attached to the axle.

The final touch- handle. It is made from a piece of the same pipe that was used for the axial rod or a diameter more suitable for the hand. The mounting method depends on personal preference. The handle can be welded to the axle, reinforced with additional crossbars, or made removable.

Materials used

Depending on the type of drill being manufactured, they are used various materials, but the basis is always round or profile pipes and sheet metal (waste saw blades).

Pieces of pipe, parts of broken wood drills, and metal plates are used as pikes. Or models are made without peaks. Studs and nuts are used to connect the rod segments.

In general, the range of necessary and acceptable materials depends on the chosen design. It must be thought through before starting work.

Cutting elements and their fastening

The cutting part of earth drills can be removable or non-removable. However, detachable mounting is only permissible on versions with half blades or saw blades or sheet metal. To do this, shelves are attached to the main rod, located at the same angle as the blades. 2-3 holes are drilled in the shelves, to which the cutting parts are attached using bolts and nuts.

Replacement bits can also be made for drills with an earth receiver. To do this, in the reinforcing arc that attaches the bucket to the rod, it is necessary to make a flattening, drill a hole and cut a thread in it.

The screw cutting parts are rigidly attached to the axis. For drilling holes various diameters It makes sense to make several attachments for one handle.

Some modifications

1. Straight crushing blades between lance and cutting edge.
2. Multi-tier arrangement of blades with gradually increasing diameter.
3. Power ribs between the corners of the blades and/or the axial rod.
4. Drain box to choose from more soil in one run.
5. Additional blade with 2-3 teeth for easier drilling in dense soils.
6. Removable blades for quick replacement during work.
7. And many others, the number of which is limited only by personal ingenuity.

Drill for TISE piles

Fundamental difference drill for constructing pile foundations consists of a folding blade and a container - a land receiver. It is often manufactured as a separate tool along with an auger drill for the actual wells.

The blade folding mechanism is a rod that moves a small piece of larger diameter pipe that is placed on the main rod. This movement activates a system of levers that lowers the blade.

Auger drill

To make multiple holes, it is better to use an auger drill. For one-time projects, a fishing ice pick is quite suitable. But for the mass installation of holes, it is better to purchase or make an appropriate drill from pipes and other materials.

In a “working” auger drill, only one edge of the blades protrudes. The second can be equipped with a comb with several teeth located slightly below the cutting plane.

If you have the time and money, using a motorized block and a special bed will help significantly speed up drilling holes for fence posts.

Blueprints

The abundance of designs allows you to create a highly specialized tool for personal needs. Let's look at some drawings of such options.

Shovel drill

When planting plants, the drilling depth is not critical. Therefore, you can donate an old shovel to make hole preparation easier. You should retreat 30 mm from the lower center point. Draw lines from it to the edges at an angle of 10-20 degrees. Then step back 30 mm from each edge and draw vertical lines. The bayonet segments located between the verticals and lines diverging from the center are cut out.

Then cut the marked 30mm from the bottom center point. Now all that remains is to bend the lower and side parts of the bayonet in opposite directions along the marked lines. The earth drill with your own hands is ready.

This is what the new drill looks like

Surely the owners land plots at least once in your life you have had to deal with the need to dig holes, which are required to install pillars, supports, arches and other parts involved in the arrangement of the exterior. Narrow holes and wells sometimes have to be made in inconvenient places or difficult soils. An ordinary shovel cannot cope with digging deep holes, so the owner has to rent a drill or hire a specialist to handle the tool.

A garden drill is a useful tool for a summer resident. It is light and compact, easy to transport and easy to use. Made of hard metals, it splits small stones and plant roots hidden in the depths of the earth. To dig holes, use it by placing it in the desired place and making several rotational movements, similar to a kitchen corkscrew.

Description of design

The main purpose of the drill is to dig wells to the depth of a columnar foundation. The holes are made by the cutting part, the shape of which can be different:

• In the form of a screw;
• Two-blade;
• Helical;
• In the form of half-discs;
• Multi-tiered;
• Removable or fully welded.

Some models start with small blades with gradually increasing to the largest ones at the top. But factory-made drills do not always turn out to be functional in practice, because the tool may not penetrate into the ground to the required depth or its attachments may not coincide with the expected diameter of the hole. And although the price finished product is small, it makes sense to learn how to make it yourself. The technology for creating a drill at home is simple and inexpensive; it is only important to decide on the configuration of the model.

Let's look at a few differences different designs responsible for the functionality of the tool:

1. Baking powder. The item looks like a pair inclined planes or auger. In the second case, a spiral-shaped knife is located on a rod.
2. Ground receiver. Soil accumulates in the so-called storage facility. The part facilitates work when drilling holes with a diameter of 35 cm.
3. Shaper plow lower extended zone. The use of the structure helps to strengthen the columnar foundation, which is important when constructing massive structures.

The bolted connection of the drill secures the auger part to the handle. The length of the assembled product slightly exceeds 1 m, thanks to which the tool makes holes up to 700 mm. If you need to dig holes of greater depth, the structure can be supplemented with a connecting tube (500 mm). The element looks like a part with a bolt and nut, the location of which is the end sections of the pipe.

Manufacturing and selection of components

When making a hand drill for digging wells under pillars with your own hands, there are usually no difficulties. But during the production process, the craftsman will need parts and materials from which the finished product is made.

Parts List

• Bolt and nut M20
• 2 discs with a diameter of 100 and 150 mm
• Tip and drill 20mm diameter
• Three pieces of pipe: two - 500 mm each and one piece of 400 mm. Additional parameters: wall thickness – 3.5 mm, outer diameter – 40 mm.

Necessary materials

Required wall thickness iron pipes(3.5 mm) is explained by the strengthening of the product and the ability to work in hard soil. Discs for work can be removed from the circular saw or made independently. They will need metal sheets with minimum thickness 3 mm.

Tools that will be useful:

• Hammer and grinder
• Welding technology
• Locksmith kit
• Electric drill with metal drills
• Sharpening wheel for cutting elements.

If there is no tip with a drill, they are replaced with a drill with a tapered shank. The diameter must match the screw part. To avoid injury in home production, use soft bicycle handles.

Step-by-step description of tool manufacturing

Application of protective coating

To prevent corrosion processes, all parts of a hand drill made for installing poles with your own hands must be cleaned with sandpaper, treated with a phosphating solution and primer. After this, the product can be painted.

Already during operation, after each work, the drill must be disassembled to clean the bolted connections from dust and coated with waterproof lubricant. Don’t be lazy - careful care of the tool prevents jamming of bolted joints and guarantees long-term operation of the entire structure.

Methods to improve tool performance

In the process of work, builders have to deal with an abundance of roots of various vegetation lying in the ground. The sharply sharpened edges of the knives make the drill easier to operate. Also, for ease of work, you can cut teeth on the sloping part of each blade or round off the cutting area.

Ways to improve the design

Drill with replaceable cutters

The first “highlight” will be the manufacture of a drill with replaceable cutters. Thanks to this tool, the master will be able to dig holes of any diameter. In addition to making spare elements, it is important to provide a method for attaching them to the collar. The easiest way to connect products is with two welded iron plates. In relation to the plane of rotation, welding is performed at an angle of 20°.

Holes for bolts are drilled in the blades and mounting plates - 2 pieces each. on every detail. The cutters are screwed with M6 bolts with washers and nuts. To prevent the bolts from interfering with drilling, they are inserted with the threads facing up.

The second way to improve the drill is to enhance the functionality of the lower end of the driver. A narrow plate of 10 x 2 cm is cut out of sheet iron and ground into a cone with a grinder, giving it the appearance of a point. No cuts are made at the end of the knob - a turned plate is inserted into this part of the product, welded and flattened. The result should be something like a peak.

This is how the pike is made differently. The plate is cut longer (about 17 cm), heated and rolled into a screw (like a corkscrew). Work on creating the peaks continues, as in the first version.

Under the auger, you can use a drill of a suitable diameter that can handle wood or metal. An unusual tool can easily be inserted into the ground and drill it to the desired depth without problems.

Third tip useful for builders working on compacted deep soil layers. If a small flat cutter is welded between the peak and the cutter, the device can be used to perform preliminary loosening of the soil and additional centering during drilling. To make this part you will need 2 plates measuring 8 x 3 cm. It speeds up the work process.

Fourth: you can get friezes from grinder discs designed for
stone processing. The circles are cut along the radius line and the central hole is expanded, adjusting the hole to the diameter of the knob. Its extension with the ends moving apart in different directions gives the appearance of a screw. All that remains is to weld it, as described above.

Making a cutter can be easily done from a circular saw blade. The sharp teeth of the modernized model will easily cut through unruly roots of even the strongest vegetation. What you choose for yourself, decide for yourself. In general, making a drill is not difficult and requires minimum costs. The whole process takes about 2 hours.

DIY hand drill

The operation of a universal hand drill will be more productive if the auger blades are removable and not tightly coupled to the stand. And if you supplement the product with round blades of various sizes and configurations, the drill will become a truly multifunctional device that will be useful to a person in many household matters.

Experienced craftsmen say that blades with a diameter of 9 and 12 cm do an excellent job of drilling holes for water wells and seedlings, arranging holes for the construction of greenhouses and for installing tunnels for laying underground communications. Large knives with a diameter of 17 and 25 cm will serve rational decision for those who fill fence supports and small buildings, arranges compost pits and plants plants with powerful rhizomes, builds wells and surrounds the area with a fence.

Step by step photo guide:

To maintain a given angle of inclination of the lever, which will serve as a handle, when connecting the part to the stand, it is recommended to use welding clamp. The handle must be attached to the stand itself at a right angle.

And one last piece of advice: on the eve of drilling, loosen it with a shovel upper layer soil. Then the tool will go into the ground easier. We hope our recommendations will help you without extra effort make a functional drill that will last for many years and bring many benefits to the household.

During construction and arrangement land plot, very often you need to do round holes in earthen soil. Such pits are needed for light utility structures, these include: arched structures, fences, pillars and other buildings. Even the holes that are made when making a pile foundation, only of a smaller diameter, are also made with a hand drill.

Types of equipment

In what cases can it be used this type equipment:

• When utility networks are laid.
• For the construction of a well.
• For installing a load-bearing base on piles for light outbuildings or other structures.
• When installing a fence.

Types of structures and their technical characteristics

In the past, vertical shovels were used for such purposes. They have been replaced by new, improved, simple models that will greatly facilitate all types of work.

A few simple kits:

The simplest mechanical device

It is a conventional double-sided equipment with a tubular rod, a handle and a cutter with 2 blades on the other side.

Used for digging shallow holes and shallow wells.

Model with removable cutters

It can be used for all types of work

Auger drilling device

The main differences of the improved hand model, this is that behind the cutting blades there is a screw auger. Thanks to several cutters and a split design, work is carried out quickly, and due to extension, penetration occurs to the required depth.

Fundamental manual equipment "TISE": characteristics and production

Today, in private suburban construction More and more often you can find drilling operations with a load-bearing foundation. In frequent cases, individual construction opts for TISE, the optimal solution in terms of cost of work and quality of execution.

Modern device for wide use

The operating principle of the drill will ensure comfortable work:

• The presence of sliding sections of the rod allows you to adjust the desired depth, since the length of each part is 1.10 m.
• The equipment is equipped with a soil receiver with a diameter of 20.5 cm, which exactly corresponds to the size of the holes.
• In order for the well to be vertically ideal, a cylindrical accumulator is used.
• If during drilling operations obstacles form in the ground, a guide pin will come to the rescue, which will be responsible for the given direction in the event of interference.
• Auger plates and special loosening cutters, which are located in the lower part of the receiver, are responsible for collecting soil.
• The device is equipped with a folding paddle, which is raised by a cord and lowered by its own weight.

There are only two versions Borax TISE, which differ from each other only in the storage device.

TISE drill: manual assembly in several versions

A drill made independently can be thought of as 2 different pieces of equipment: one model with an extension, the other designed for drilling, a simpler design.

Manual assembly for drilling work, without expansion:

• You will need 2 pieces of regular water pipe(diameter 210mm and length 150mm).
• A bottom is welded on one end of the pipe, and a removable chamfer on the other.
• A thick drill and auger are mounted in the center.

For telescopic rod you will need 2 pipes (250x250 mm and 200x200). This design can cope with drilling difficult soil up to 100 mm, and the wall of the cup will be perfectly smooth.

After watching the video review, you will be able to understand in more detail the assembly of the equipment and the principle of its operation:

To prevent soil from sticking to the walls of the well, you can use machine oil.

Assembling the device for expansion:

• This device has a more complex structure. A pipe with a diameter of 210 mm and a length of 800 mm is used for the glass.
• The second glass is made 50 mm smaller in diameter.
• Next, there is also a chamfer and a bottom, which acts as a storage tank for soil, holes are made there.
• A rod made of a pipe 200x200 mm in diameter and 100 cm long is attached in the center, into which a device made of bearings is mounted.
• Then you will need a steel angle, 250 mm long, connect it to the sleeve. Using a bolt up to 2 cm, we weld it to the dead rod (the design resembles a door hinge).
• No. 21 Device with extension
• A 250x250 mm pipe is mounted on the rod, and a sleeve with a bolt is welded to the bottom, onto which the 2nd angle is attached and connected to the first.
• Thus, we get a mobile device.
• Finally, we screw on the blade of the shovel, which visually resembles a simple plow for cleaning the bottom.

Schematic drawing of manual assembly

Mechanical hand pole equipment, application, work quality

Among the many models, I would like to highlight one of the universal drilling devices, the earth drill. The equipment is designed for a wide range of tasks. Used as in professional field, and for individual construction.

Using the equipment you can perform the following types of work:

1. Construction of fences.
2. Preparatory work for foundation supports.
3. For the construction of drainage wells.
4. Planting trees and plants.

The device can also be used for laying communications, i.e., for horizontal drilling.

This equipment is dismountable, lightweight, durable and easy to transport. To work with a digger, you do not need special physical training; you can handle all types of work independently, without outside help.

Types of structures for pillars

There are several types of equipment that differ in functional features and parameters.

We distinguish three groups:

1. “Pit drills” are household without a motor; the work is carried out with the help of an operator.
2. Equipment that runs on gasoline or motors.
3. Hanging structures work only with the help of special equipment.

Manual hole drills without motor

The compactness of the model is convenient to use and transport. Thanks to the equipment it is very easy to install lightweight wooden fence or just dig a hole for a well.

The design looks like this:

• Simple "T" handle.
• Rod with built-in knife.

Handmade models are made different sizes, there are also collapsible ones, which is very important during transportation. Holes are made with a diameter of up to 300 mm and a depth of up to 2 m.

Mechanized models

This is a simple piece of equipment with an electric drive and a motor. There are also gasoline models. The tool allows you to make fairly deep holes up to 3 m.

Drilling or mounted rigs

This model is designed for drilling large diameter wells. Just right for installing electric poles and serious fences, for example, airports or industrial enterprises.

How to make a hand drill yourself

Very few people know that making a hand drill can be done at home. Will need detailed instructions and availability of necessary tools and materials.

The model provided is not suitable for complex work with stony clay.

We prepare the necessary materials for production

To manufacture the equipment you will need:

1. Vise.
2. Gas keys.
3. Grinder with a nozzle for metal.
4. Welding.
5. Electric drill.
6. Die holder.

Step-by-step assembly instructions

Pipe processing

We take a piece of pipe with a diameter of 5 cm and make an oval edge.

Drill handle

We prepare a place for the drill handle. We weld a piece of metal for the drill handle to the oval side.

Mounting the nut

A nut is welded to a part with a diameter of 5 cm.

We screw both ends of the pipe. We weld a tip on one side of the pipe, and a bolt on the other and screw it to each other. We cut the discs in half.

Mounting disks

The 2 halves of the disk are welded at an angle of 40 degrees to each other on the edge of the pipe. The second half of the larger diameter is welded similarly above the first at a distance of 10 mm.

We twist both parts together. We get a hand drill.

After all the work has been carried out, it is necessary to carry out a test drilling and only after that it can be prepared for applying paint. It will take no more than 2.5 hours to make this model.

Choosing the right tool for yourself, it is better to use some recommendations that will help you do right choice, saving time:

1. When choosing, pay attention to the spiral; the speed of work depends on this detail.
2. If small-sized drilling is planned, then a flat spiral can be used.
3. When purchasing, pay attention to the speed mode of the equipment. During drilling operations, you should strictly follow the instructions so that the tool does not fail quickly.
4. If you are faced with choosing a hand drill for more serious work, then it is better to look at a model with an auger.
5. Working with manual device, it will be too tiring for you. It is necessary that the drill removes the earth from the drilling site, which will greatly facilitate your efforts.

For more detailed information, as an example of the operation of one of the types of devices, we recommend that you familiarize yourself with the video material on how to drill a well yourself using the percussion-rope method.

The video review will explain to everyone how competently you can drill a hole by hand. Practical advice will help you choose best option and take seriously the choice of the equipment you need.
