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, motorized drills are used to make a large number of holes, 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 connection to the 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 making a drill yourself are an angle grinder and a 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. For this, an old saw blade from 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 the lance and the 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 borax for device pile foundations consists in the presence 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.

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.

A garden hand auger has been and remains one of the most useful devices for garden 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 laying a 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 them ready-made from a circular saw. In the first case, it is recommended to take metal sheets with a thickness of 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 self-production 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 a 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.

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

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. A longer plate is cut out of sheet metal - 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.

Absolutely the owner land plot at least once I was faced with the need to dig holes for posts and various supports for decoration appearance plot. It happens that you need to make a narrow hole in a not quite convenient location. It will be difficult to handle with a simple shovel, and you will have to borrow a manual pole drill from your friends or even call a specialist who can deftly handle the tool.

Hand drill design

The garden auger is very useful device for any summer resident. It is very compact, convenient and easy to use. As a rule, it is made of solid metal. It effortlessly splits small stones and plant rhizomes into pieces.

With the help of such a device, you can easily dig a hole by rotating it around its axis like a corkscrew.

The main purpose of the drill is to dig holes for posts. Small wells are made by the cutting part of the device, which can be of various shapes:

• Two-blade;
• In the form of half-discs;
• Helical;
• Screw-shaped;
• Multi-tiered;
• Solid or removable.

There are models that start with small blades and their top part gradually increased to large sizes. A factory drill is not functional and effective in all situations, because the tool simply will not be able to penetrate the soil to the required depth, or its attachments will not be of the required diameter.

Although the cost of a factory-made pole drill is relatively affordable, it is quite possible to make a useful tool yourself, and at the same time it will meet all necessary requirements. The technology for making a drill with your own hands is very simple, and its cost will be much cheaper than a factory one. You just need to decide on the parameters of the product.

Let's look at a few various designs, which are responsible for the efficiency and functionality of the drill:

Materials and tools

In order to make a hand drill for poles, as a rule, it is not necessary special effort. But the craftsman needs materials and components to create the product.

List of required parts:

• Nut and bolt M20;
• Disks with a diameter of 100−150 mm - 2 pieces;
• Drill with tip (20 mm in diameter);
• Metal pipe sections: two 500 mm and one 400 mm. The wall thickness should be 3.5 mm, the outer diameter should be 40 mm.

The wall thickness of the metal pipe must be exactly this in order to ready product it was durable and could work with any, even quite hard, soil. The discs can be taken from a circular saw or you can make them yourself. For homemade disks, you will need sheets of metal at least 3 mm thick.

From tools when creating a product you will need:

• Bulgarian;
• hammer;
• welding machine;
• drill;
• metal drills;
• blade sharpener.

If you do not have a tip with a drill, you can replace it with a drill with a cone-shaped shank. Its diameter must match the screw. In order to avoid injury, it is recommended to use soft bicycle handles.

Step-by-step production of a drill

On metal sheet draw a circle, marking the center. This will be the blade. Next, this circle needs to be cut out using a grinder, and then a cut line must be drawn that runs along the diameter line. Then we draw a cutting line, which should correspond to the circumference of the collar. The resulting disk must be divided into two parts and holes for the knobs must be cut.

At the end of the pipe, which will act as a wrench, we use a grinder to cut four longitudinal lines, 3-4 cm in length. After this, you need to form a tip from them using a hammer, while you need to collect the cuts at the very center of the pipe. The resulting tip must be processed by welding and ensure that the knob does not become clogged with soil during operation.

The next step is to connect the knob to the disk by welding. This is done at a distance of 5 cm between them and at an angle to the plane of rotation of 20 degrees.

Next we proceed to the extension pipe, which should be equipped with a handle. This part must be welded in the letter “T” and be sure to weld the amplifiers to it in the form of a “kerchief”. The workpiece is threaded through the driver, and a hole is made through them so that the parts can be fastened with a pin. Several such holes need to be made in order to be able to adjust the length of the product.

The work ends with sharpening the blades. The edge of the cutter must be processed in such a way that when rotating, the tip of the blade is directed downward.

Protective covering

To avoid rust on the parts of a homemade pole drill, you need to thoroughly clean them sandpaper and treat with a primer and phosphating solution. After this treatment, the finished product can be painted.

When using the device, you need to disassemble it after each use and clean all connections from dust and dirt, and also coat them with a special lubricant that repels water. Don't miss this moment, because proper care behind the tool will be a good prevention of bolt jamming and will allow it to work smoothly for a very long time.

Ways to improve the tool

When drilling holes, the master may encounter a large number of plant rhizomes that lie tightly in the soil. The sharp edges of the blades will make working with the drill much easier. For ease of use, you can cut several teeth on the sloping area of ​​the blade or round off its cutting area.

The design can be improved and removable drill bits. Thanks to them, it will be possible to drill holes of any diameter. In addition to the manufacture of spare parts, it is necessary to provide for their attachment to the collar. The easiest way is to connect them with two iron plates, which are secured by welding.

In the mounting plates, as well as in the blades, you need to drill two holes for the sides. The cutters are fastened with M6 bolts. To ensure that the bolts do not interfere with work, they must be screwed in with the threads facing up.

There is another way to improve homemade drill for pillars. You can increase the efficiency of the lower end of the knob. To do this, you need to cut out a narrow metal plate (10x2 cm) and grind it into a cone shape using a grinder, making a kind of point.

There is no need to make cuts in the collar; turned metal plates are inserted into its end, fixed by welding and flattened. The result should be a peak.

There is another method for making a pike. A metal plate is cut to a length of about 17 cm and a screw is made from it, similar to a corkscrew. Further, the algorithm of actions is the same as in the described first option.

A suitable drill can act as an auger, which can easily handle wood as well as metal. Such a tool will penetrate the ground much easier and will drill a hole to the required depth without any problems.

Builders who work on dense deep layers of soil will need one piece of advice. Between the pick and the cutter you need to weld a small flat cutter. Thanks to this design, it will be possible to loosen the earth and center it when drilling. For such a part you will need 2 metal plates 3x8 cm. This trick will significantly speed up working with the tool.

Milling cutters can also be made from grinder discs, which are designed for working with stone. The circles need to be cut along the radius and the hole in the center should be expanded according to the diameter of the knob. Bending the disk with the sides apart gives the appearance of a corkscrew or auger. All that remains is to weld the part in the manner described above.

The cutter is very easy to make from a circular saw blade. The teeth of this model can easily cope with plant rhizomes and hard soil.

The master can choose how to modernize his drill independently. It is worth saying that making a drill for poles with your own hands is not at all difficult process and requires minimal physical and financial costs from the master. The entire manufacturing process takes two hours at most.

Finally there is one important advice : before the drilling process, it is best to loosen the soil with a shovel, then the device will fit into it more easily and the work will go much faster. The recommendations given will certainly help the master make a functional and effective tool that will serve him for decades and become a very good assistant.

Installing a pole is not such an easy task, especially digging a hole for it. A pit is necessary in various construction works, such as building a foundation or a fence. You can’t do it with an ordinary shovel, so they use a special tool - a drill (pit drill, earth drill, etc.). A post drill, like any other tool, has its own characteristics.

A hand drill will help you make a hole of the required size

Types of drills

A drill is a type of construction equipment whose function is to make a hole the right size. It is used in different areas. For example, in the construction of bridges and fences, for gardening work(when planting trees and other vegetation).

Drills can be divided into several main types, which differ in size, purpose and power.

They can be divided into:

1. Hand drills. They are often used in everyday life by both beginners and advanced summer residents.
2. Designs with automatic drive. Modernized hand drills. A motor is installed on them.
3. Mounted. These are the same mechanized drills, only with the possibility of installation on special agricultural equipment (tractors, walk-behind tractors, etc.).

The first ones have the weakest design and purpose. They drill holes of small diameter and depth. Without the effort of the worker, such a tool is useless. But its advantage lies in its compactness, since it is small and light. It is quite convenient to transport it. With this tool you can easily make a hole for a fence or seedlings.

In this video we will look at how to make a hand drill:

It consists of a rod and a T-shaped handle on top of the structure. There is a metal tip at the bottom that performs the function of centering the tool. A little higher is the drilling mechanism itself, designed in a spiral shape. Often consists of 2-3 rows of metal round cutters. As an alternative, use a saw blade as the cutting part.

As a rule, such a tool can make a hole up to 2 meters with a diameter of up to 30 cm. The drill is made collapsible for more convenient transportation. The metal pipe is made of two parts (collapsible). The blades are also often made removable with bolts.

Power drills are made with a drive system. The design is more complex, but most summer residents can make such a manual drill for poles on their own. The drill also has metal pipe with handle, tip and cutting part. But an additional motor with a gearbox and drive part is installed. The auger (cutting) part moves due to rotational movements transmitted through gears from a gearbox with a motor.

This design is more powerful, but its strength depends directly on the performance and strength of the motor. The hole can be made deeper, up to 3 meters.

Mounted drills are designed to perform more complex work. The width and length of the holes are much larger. They are often used for the construction of bridges, train stations and other industrial purposes. With their help, you can make sheet piling fences for pits and trenches. Thanks to attachments, the cost of construction work is significantly reduced, as they have greater productivity and power.

Nuances of choosing a model

Today there are a huge number of purchased models, and often make right choice pretty hard.

When purchasing, first of all, you need to pay attention to specifications, namely:

• maximum pit depth;
• drilling width;
• work productivity (drilling speed and number of holes over a certain period);
• drill power.

When renting, you also need to take into account the cost of delivering the drill to the desired location. Before buying a rotator for the ground, you should pay attention Special attention knives. They need to be very sharp and preferably self-sharpening. They must be made of high-quality metal, as they will break stones, soil, cut grass, etc.

Caring for the bracelet

First you need to understand the main rule - to use the tool exclusively for its intended purpose. You can make a hole only when you are sure that the drill is intended for certain type soil. If he is unable to work on such ground, he will most likely break on the first try.

You need to carefully read the instructions and technical specifications and not demand more from the tool than it is capable of performing. It is also necessary to study technical features work. For example, with a hand-held hole drill you can make no more than 35 holes per day.

When working, the additionally installed tripod system greatly helps. It fixes the drill and makes it easier to pull it off the ground. And a special lever will help you get it out. It is clamped, and the drill is turned counterclockwise and removed. For long-lasting operation, it is recommended to lubricate the drill with anti-corrosion substances, and also paint it to secure the result.

Preparation for drilling

Fence holes will begin to be made only after the necessary preparatory work Location on. At the same time you need to do appropriate markup. Separately on the site you need to make wells for supports for gates and gates, if this is provided for by the layout of the building.

To install fence supports, they must be lowered to the appropriate depth. Not everyone knows what it should be. As a result, incorrectly installed supports cause the fence to fall over time, or their shape becomes deformed.

Make your own hand drill

You can do this job correctly with a few tips:

1. To install the pole, you need to drill a well. Its diameter should be slightly larger than the diameter of the pillar. In this case, there is no need to make excessively wide holes, as they greatly loosen the soil. And when you make the width of the pit the same as the width of the support, then it will not be possible to mount it in this way.
2. The number of holes required for the fence can be calculated without any problems. To do this, the perimeter of the fence should be divided into the number of sections. Add to the resulting number two more holes for the gate and two for the wicket.
3. The depth of the holes must correspond to the weight, length and width of the pile. It is also necessary to pay attention to the type of soil, The groundwater. If the soil is unstable, then the depth of the holes should be at least 1.2-1.5 meters.

The depth of the pit must be greater than the possible depth of soil freezing in very coldy. If the soil is dense, then the hole can be made up to 1 meter. In this case, the support itself must be at least 1/3 in the ground. This way the fence will be very strong and reliable.

Required Tools

Not everyone can make a well, and this work is not easy. Each hole must be the same diameter and depth, which usually takes a lot of time. Great importance has a choice the right tool. You can make such a well using various equipment: a specially converted shovel, a hand drill, an automated drill or a mounted installation.

Pros and cons of a shovel

A shovel is the cheapest tool, but its effectiveness is low. It will not be possible to dig a deep hole with such equipment, just as it will not be possible to dig a narrow hole or too wide one. In addition, the diameter of the holes will always be slightly different. But if the fence is planned to be made of brick, then a shovel will ideal option. If the tool is damaged, it can easily be replaced with another one, since the cost is low.

Advantages and disadvantages of a garden auger

Such equipment is quite popular, although every household does not have it. In most cases, it is used for digging holes for planting vegetation and for other needs in the country. It is relatively heavy when compared to a shovel, but the quality of the work is much higher.

Its design includes three parts: auger, drill handle and metal rod. A tip is also attached to the bottom of the metal rod, which performs the function of centering the drill. The diameter of the cutting part is about 15-20 cm, weight is 10-15 kg.

If you buy such a tool, you need to pay attention to whether it is sharpened accordingly. If not, then it needs to be sharpened before work. For this, it is better to use a grinder, but you can also do it with a hand file, although this is ineffective.

The tool can be used not only for making holes for fences. Often also used for planting trees, making holes for foundation piles and other work. You don't need any special skills to use it, so anyone can do it. In addition, the garden auger serves for quite a long time at correct operation and prevention.

Autodrill with drive

Making holes using a motor drill is very fast, but the method is quite expensive. The design consists of a drive (motor, gearbox, gear system) and an auger drill attached to it. Purchased options run on gasoline, diesel or electricity. This depends on the device manufacturer.

With the help of such equipment, you can drill holes up to 3 meters deep and do it in a matter of minutes. But along with its advantages, an automatic drill also has its disadvantages:

• loud noise during operation;
• if the motor is electric, you need to constantly be close to the outlet;
• Buying gasoline to run the engine will not be cheap.

To construct a fence, it is necessary to make holes to a depth of at least 80 cm. And if you multiply by the number of pillars, the figure turns out to be quite large. A hand drill will take a long time to complete the job. Another thing is a motor drill with an automatic drive.

To drill deeper holes you will need attachments, which is installed on cars. Often they make holes for artesian wells. They are not used for the purpose of constructing a fence.

Effective work

In order for drilling to be effective, you should remember some nuances. For example, it is necessary to do a large number of holes for the fence, but you need to save money. In this case, it is better to choose a garden auger, but with a well-sharpened cutting part. The tip and side edges also need sharpening. Only after this can you proceed to work. In a pre-marked place, the drill is placed in a vertical position, after which holes are drilled for the fence posts.

When there is a lot of clay and sand in the ground, then after a few turns it will be difficult to drill. To solve the problem, you need to pull out the drill and pour a bucket of water into it. After 15 minutes, you can continue drilling the hole under the pillars. Then the work will be much easier to do. If the drill is stuck in the hole, it must be loosened from side to side and then pulled out. It will be easier to do this. There may be a lot of soil on the auger. You need to remove it with a knife, then add more water and continue drilling.

The choice of purchased inventory is very important point for successful hole making. The quality of the work performed, its speed and practicality will depend on the characteristics of the tool.

To do this, you need to listen to some recommendations:

1. When purchasing, first of all you need to pay attention to the spiral. It must be sharpened.
2. The flat spiral is suitable for drilling small holes.
3. Hand drills for wells, poles, and fences should be selected carefully. You need to pay attention to the speed of work. It must be optimal.
4. If you need to do more serious work, then it is better to buy an auger drill.
5. Having a container for collecting soil makes the work much easier.

Drilling a hole is a rather complex process. For this it is better to use automated designs. But if the budget is limited, then purchasing a hand drill will be simply necessary. In addition, a small fence can be made with such equipment.

When building houses and other landscaping work, it is often necessary to make round holes in the ground for pillars, supports, arches and other parts that make up the exterior. An ordinary shovel will not help dig a deep hole, so the owners rent a drill and hire a specialist who knows how to operate the tool. To drill wells, you can also use a homemade pole drill.

Design features of the device

A hand-held post drill is designed to create holes in the ground at the level of the columnar foundation. That is why the design includes a significant cutting part, which differs in different types devices. Very important nuance thing is during rotation Soil masses must be excavated with further accumulation in the receiver.

First stage - correct selection unit design. There are some assembly features on which the further functionality of such a tool as a hand-held earth drill depends:

Before you make a drill for poles with your own hands, you must prepare drawings. They directly depend on what requirements are put forward for the design.

Types of tools

One of important parameters- the shape of the cutting plane and its location on the rod. If the planned volume of work is insignificant and the diameter of the wells will not exceed 20 cm, then you can focus on the auger model.

This design is characterized by relative ease of manufacture; there is a significant selection of materials for the cutting part. But it is worth considering some of the following features:

• To remove soil residues, the post drill must be constantly removed from the holes;
• the lower extended part of the foundation is missing;
• If the auger cavities are completely filled with soil, significant effort will be required to remove them.

An alternative is a device having a set of replaceable knives. They are installed on special mounting platforms, positioned at an angle to each other. The unique shape allows you to obtain different wells using the same device. Additionally, it should be noted that there is minimal labor involved in manufacturing and the ability to install new parts to replace those that are broken. The disadvantage is the same as that of screw products - low productivity.

All these disadvantages are absent in a hand-held earth drill with a cylindrical cutting edge. The lower part is made up of two planes located at an angle. The soil is collected into a receiver of sufficient capacity.

Main feature - presence of a mounted plow, with the help of which the diameter of the well expands directly near the base. It can be installed on all models, but only the last one can achieve maximum efficiency.

Once the design has been determined, the manufacturing itself can begin. Can't do without Supplies, good welding machine And cutting tool- grinders or hacksaws for metal.

The simplest model is the one that uses replaceable blades. How raw material for production, you can use metal discs of unequal diameters (160−350 mm). Dimensions of internal landings holes must be different. This is the only way to maintain the main advantage.

In the process of manufacturing a structure, you cannot do without the following components:

The angles between the planes of the two halves of the cut disks of the post drill should be 30 degrees. This is necessary to ensure optimal soil cutting without putting in significant effort. If you undertake the manufacture of a plow structure, then order the cutting parts separately or purchase ready-made ones.
