How to make a homemade earth drill (pit drill, earth drill)

When building a house and landscaping a site, it is often necessary to make round holes in the ground. They are needed when constructing a fence - for installing poles, when building gazebos, installing arches and other light utility structures. The same holes, but with a larger diameter and depth, are required when constructing a pile foundation. These holes are made with a motorized or hand drill. There are plenty of them in stores, but many people prefer homemade ones: they are often more productive and reliable than factory-made products. In addition, you can make a drill with your own hands of any design, and there are many of them.

Designs and Applications

There are three main designs of earth drills:

• Garden. Usually these are two semicircular blades welded at an angle to one another. A hand drill of this design is used to organize holes for planting plants, which is why it is called “garden”. But the same tool is used to make holes when installing posts for fences, gazebos and other light buildings.

• Auger drill. It differs in that it has a longer cutting part. It is used for the same purposes - to make holes for pillars. Due to its design - a longer cutting part - it needs to be removed less often, so drilling usually goes faster.

  
  The auger drill is distinguished by spirally wound several turns of the spiral

• Drill for TISE piles. This design is similar to a garden auger, but has an additional folding blade to form the expansion at the bottom of the pile characteristic of this type of foundation.

Garden earth drills that are easier to make. Depending on the type of soil on which drilling is carried out, their design is slightly modified. This is the beauty of homemade drills - they can be “sharpened” to specific conditions and it’s not just about the size - the blades can be made removable, bolted on, but also about the design features. Yes, ordinary drills in the store are inexpensive, but they are “universal”. They work well on “light” soils.” On loams, clays, marl, etc. they are ineffective.

general information

A hole drill is a special tool for making holes, boreholes, holes and other round-shaped depressions in the soil. They are used for:

1. Installation of enclosing structures.
2. Manufacturing of columnar foundations.
3. Planting crops.
4. And many other household purposes in which you need to equip holes in the ground.

The main task of the device is to quickly and efficiently make cylindrical holes without significant labor costs. Depending on the design, pit drills are:

1. Mounted.
2. Manual.

The first option is intended for installation on a tractor or a special platform with an electric drive. A striking example of such a model is the MTZ pit drill.

As for manual devices, they can be equipped with a mechanical, electric or gasoline drive. There are also homemade inventions that have a simplified design and can be easily made at home. With their help you can drill holes up to four meters.

In this video we will look at a self-made hole drill:

The scope of application of the device is very diverse. In most cases, they are used to make round holes in the soil for fencing structures, poles and other structures. If it is necessary to equip a pile foundation, then you cannot do without the appropriate recesses. Only their diameter will be more impressive.

To perform such work, a mechanical or motorized hole drill is used. In construction hypermarkets, such equipment is sold in large quantities, but craftsmen prefer homemade inventions, arguing that they are accessible, cheap and reliable. In addition, with a small investment in a short period of time, you can produce a truly powerful tool that will surpass factory devices in performance.

Making a garden drill

A garden auger is the simplest but most effective design. It consists of:

• Cutting part. It usually consists of two steel semicircles with sharpened edges. The diameter of the blades is selected depending on the diameter of the holes that need to be drilled. For convenience, the blades can be made removable - bolted.

  
  The post drill can be equipped with a prefabricated rod

• Kernel. This is a round or profiled pipe (square cross-section). A crowbar can also be used, but it is very heavy and will be difficult to work with. The length of the rod is the required depth of the hole plus 50-60 cm. If you make it shorter, then the last centimeters will have to be drilled in a deep slope, which is not at all easy. If this calculation results in a total height higher than 1.5 meters, it makes sense to make a prefabricated rod. Then the rod is extended with pipe sections of the same diameter, creating an articulation system.
• Pen. Most often, a crossbar in the shape of the letter T is welded to the rod. The minimum length of the handle is 40 cm, the optimal length is about 50-60 cm.
• The tip is a drill. This is the part that is under the blades. It is the first to loosen the soil, and at the initial stage it is responsible for centering the drill - it is easier to hold it vertically.

This is a basic design, and there are many modifications to it. But let's first talk about what an earth drill can be made from.

Materials

As already mentioned, the rod is most often made from a round or square pipe. Diameter - from 3/4′ to 1.5′, profiled pipe can be taken from 20*20 mm to 35*35 mm.

Blade knives can be made from:

• sheet steel with a thickness of 4 mm;
• saw blade for an angle grinder of suitable diameter.

It is easier to make blades from a saw blade. In this case, the cutting edges are already ready. It will be possible to further sharpen the side edges to make the soil easier to cut.

The spear-drill is made from different materials - there are many different designs. They just make a sharpened rod. Then you need a piece of large diameter rod. The second option is to make something like a drill from the steel strip. And yet - a combination of these two.

Pike - one of the tip options

Combination tip for crushing rocks

And finally - about the pen. It is more convenient if it is made of a round pipe. Its diameter can be selected according to the circumference of the palms. The main requirement is that you should be comfortable.

Knives and fastening method

First of all, you need to decide whether you are making a drill with your own hands with removable or stationary blades. If the blades are removable, weld shelves made of thick steel at one end of the rod. The shelves are made at an angle - so that the planes of the knives are separated at an angle of 25-30°.

After the shelves are welded, two or three holes are made in them for fasteners. Then the same holes will need to be made in the blades, and installed on bolts of substantial diameter.

One rod can have several sets of cutting blades - for holes of different diameters

You will have to cut holes in the center of the disks themselves so that they fit more tightly to the rod, but this operation is also required for the monolithic version - with welded blades.

Sheet steel

If you are going to make the blades from sheet steel, cut out a template from paper and use it to create a circle of steel. Drill a hole in the center - you will need to insert and weld a rod into it. Circle or square - depending on the chosen rod. The hole dimensions are slightly larger than the dimensions of the rod.

Next, you need to decide what kind of blades you will make - from two halves of a circle (as in the photo above) or in the form of an open circle with offset edges - one turn of a spiral (in the photo below).

Manual drill with one turn

The edges should also be separated by 25-30 degrees. In this case, drilling efficiency will be maximum. If you work on dense soils (clay, loams with a predominance of clay), the blades may collapse under load. To avoid this, stops are added from a corner or a thick strip of steel.

Strengthening a hand drill for drilling wells in dense soils

The blades bend due to the fact that unhardened steel is used, but it is almost impossible to find it in the sheet, and even if it is possible, it is unlikely to be bent.

From a saw blade

If you have an old saw blade of a suitable diameter, you have found an almost ideal option. They use hardened steel, which is elastic and durable. But such a disk cannot be bent, so it is sawed in half and these halves are placed at the required angle.

The disc is sawn in half

This homemade drill for excavation works shows quite high productivity. Even used wheels have a well-ground edge. And to make drilling even easier, they also sharpen the drill on the sides with their own hands.

Modifications

In dense soils, it can be difficult to cut the soil with large blades. In this case, several blades of different sizes are welded onto the rod. From below, near the peak, the smallest ones are welded; above, retreating a few centimeters, the large ones are welded. There can be three such tiers, maximum four. The entire cutting part should not be more than 50 cm, otherwise it is physically very difficult to work.

Cutting blades can be arranged in several tiers

If a drill is needed for shallow holes - for installing poles, etc., then this design is optimal - it is relatively light in weight and easy to work with. The working process is as follows: they lowered it into the hole, turned it several times, pulled it out, and poured out the soil stuck between the blades. But if you need to drill deep holes, you will suffer from carrying a small amount of soil from the depths. For such cases, a box for collecting soil is welded above the blades.

A homemade drill with an earth receiver is suitable for installing poles and piles

And all these are hand-made drills. All of them are highly efficient - it’s much easier to work than store-bought ones.

Design features of the pit drill

Pit drill device

When making a pit drill, you must remember that in the classic version this unit consists of two parts. The first is the working body, the second is a vertical stand with a handle for easy grip. The basis of the unit is the pin. A strip of metal sheet in the form of a spiral is attached to its side plane. At the end of the pin there is a sharp blade made of durable materials.

When the handle rotates, the tool goes deep into the ground. It cuts small roots and moves soil to the surface using an auger mechanism. To dig a deeper hole, the stand is equipped with additional inserts. It’s good when the end of the pit drill is pointed, like a spear. In this case, he will perform all tasks more accurately and efficiently.

Auger drill

Due to the large number of turns, an auger auger creates significant resistance, that is, it is much more difficult to work with it than with a garden auger. But augers are used mainly in the presence of a mechanized drive - when making a drill for deep wells - for water, for installing underground probes for a heat pump, etc.

This is what an auger drill looks like

To make a homemade auger drill, you will need several metal disks. The number of disks is equal to the number of turns. The disks are cut identically, a hole is cut in them in the center for the rod, as well as an identical sector - so that they can be welded.

A sector is marked in the rings and cut out

The discs are welded on one side, then, slightly stretching the resulting accordion, the seam is welded on the other side. Rings are welded on the outer disks. The welded discs are placed on the rod, the lower edge is welded.

It turns out to be such a big spring

Next you will need a winch. The blank for the auger is secured, the winch hook clings to the ring and is stretched to the required length, after which the auger is boiled.

Almost done

Use of sheet steel

Before making a hole drill with your own hands, the drawings should be considered first. You will have to compose one of them yourself or use what is suggested in the article. If you plan to make the blades from sheet steel, then you must first make a template from paper. In the center of the circle you need to drill a hole into which the rod is inserted and welded. Depending on which rod you prefer, you will need to make a square or a circle.

In this case, the hole will have a slightly larger size compared to the parameters of the rod. You need to decide what kind of blades you want. They can have two halves or can be represented as an open circle with offset edges. The edges must be spread at an angle of 30°. In this case, drilling efficiency will be maximum.

If you are making a hole drill on a tractor with your own hands, with which you will work on dense soils, then the blades can be brought together under load. In order to avoid this, it is necessary to make a stop from a corner or a thick strip of steel. The blades will bend, because the steel used is not hardened, but it is almost impossible to find it in the sheet. If you solve this problem, then it is unlikely that you will be able to bend the material.

Drill for TISE piles

In the author's version, the TISE drill is a blade with an earth receiver and a folding wider blade, which forms an expansion at the bottom of the pile. But working with such a projectile is inconvenient - the folding knife gets in the way. Therefore, in some designs it is made removable, but in general, it is recommended to drill the holes themselves with an ordinary garden drill, and for expansion, make a separate folding knife with an earth receiver. This makes the work easier and faster.

Do-it-yourself drill for TISE piles - one of the options

A cut-off shovel serves as a knife, and the land receiver is made from a herring can. The knife is fixed movably; when lowered into the pit, it is pulled up by a nylon cable tied to the end. Having reached the bottom, the cable is weakened, the blade begins to trim the sides of the hole, forming the necessary expansion.

The photo below shows the second version of a homemade drill for TISE piles. The design is more complex, but also more effective. The plow blade is made from a piece of spring, sharpened and welded to a folding structure with bolted joints.

More complex design

The dredger is made from an old propane tank. The collection of soil occurs from below, which is why the receiver is made with a rounded bottom. It has two holes, their edges are sharpened.

Bottom view

This projectile works well even on dense clay. True, to reduce friction, the well must be constantly moistened with water.

Is it possible to make an electric model yourself?

The electric variation differs from the standard drill in that it is supplemented with an electric motor. Because of it, the process of digging wells is faster and requires less effort. And for mechanisms designed to excavate soil more than 3 m, an electric drive is necessary. The improved unit can be connected to the network (if it is used near houses), and it can also be started using an engine running on gasoline or gas.

To make your own electric drill, you will need to take a drill and an auger. Experts recommend purchasing a tool from a foreign company; the power of such a device reaches 2 kW. However, we must not forget that the drill has a third cone, so you will need a lathe for the job. With its help it is easy to make special recesses on both sides. A drill with a cone is attached to the adapter and the pointed part is cut off.

Due to the heavy weight of the structure, to use it you need to install a mounted electric winch capable of raising and lowering the drill.

Blueprints

A self-made drill is good because its design is “tailored” to its owner. During the manufacturing process, everyone makes their own changes, then many more refine the product. But it can be difficult to do without basic drawings. This engraving contains several drawings with the sizes of various drills. As you understand, the dimensions are arbitrary; they can and should be changed, adjusting them to the size of the required wells.

Shovel drill

There is no point in making a serious structure for planting plants. In this case, you can make a garden drill from a shovel. Choose a high-quality shovel made of good steel, apply markings as shown in the drawing. According to the markings, you will need to cut out two small fragments and saw the lower part in the middle to a depth of 30 cm (pictured).

Shovel drill

Next, the edges are bent one forward, the other back, and the petals formed in the lower part are folded towards them. The resulting seams are boiled outside and inside.

Drill for soft soils

If the ground is soft, the conventional design does not work very well. For such cases, there is a special drill with an extended cutting part. It is a kind of glass with slits on the sides. The cuts are equipped with cutting edges. They are best made from well-hardened steel.

Drill for soft soils

This drawing shows an interesting handle design - it can be rearranged as the length of the rod increases.

Basic drawings of auger and garden auger

Both of these units work well, but the garden one has to be taken out often, and the auger one is harder to rotate. Choose according to your own preferences.

Using the saw blade

When making a hole drill with your own hands at MTZ, you can use a saw blade. If you have one in stock, it is important to make sure that its diameter is suitable. These products use hardened steel, which is characterized by high strength and elasticity. It will not be possible to bend such a sheet, so it must be sawed in half and the halves apart at the desired angle.

Such a homemade drill will demonstrate high performance. Even if you have used discs, they will have a well-sharpened edge. In order for drilling to be effective, you can also sharpen the tool on the sides.

Baler

This equipment is difficult to manufacture from a technical point of view. But you can solve the problem if you follow these approximate instructions:

1. The running support is assembled on a pair of pneumatic wheels.
2. The front part, the pick-up and the conveyor are mounted on these parts.
3. The press chamber is mounted separately. The rollers and pressure brush should be at the bottom. The plate on the spring is placed at the top. This part is then used to press the compressed layers together. Thanks to this, the contact of the roll to the working surface will be maximum.
4. Next, the drive is assembled, from which all other working units begin to move. A cardan is connected to the 2-speed gearbox. The gearbox is a source of chain energy going to the rollers and the pick-up transport.
5. Gears are installed on the picking mechanism of the mini-tractor. The main thing is that their diameter should be larger than that of the rollers. Then the picking speed will be higher, as will the force of simultaneous pressing.

Price issue

Today you can find quite a few varieties of hand drills, which will differ in their appearance, shape, length, diameter of possible drilling, design features and other nuances.

Typically, such a tool can drill holes in the soil up to 2 meters deep with diameters up to 30 cm.

The simplest, cheapest drills usually do not stand out in anything special, have a simple shape, consist only of metal, which is painted in a certain color, often red and green.

The weight of the motor drill and the manufacturer are one of the criteria when choosing. The system that dampens vibration also plays an important role.

More expensive branded products can be supplemented with various elements that increase comfort during work. For example, the handles can be rubberized, the design can be dismounted, and the ability to extend the base of the drill can be added for drilling deeper holes.

On average, the price of the simplest drill is around two thousand Russian rubles. If you go deeper, a hand drill with a possible drilling diameter of twenty centimeters will cost two thousand one hundred rubles, and with a diameter of fifteen centimeters, two thousand. The price will also be affected by the maximum possible drilling depth.

We choose a motor drill so that it has protection against accidental starting. When you get stuck, reverse motion is an excellent help.

If we consider expensive branded models, then their cost can start from four thousand rubles and grow upward. If you have a collapsible design with the ability to increase the drilling depth, then the extension cord must be purchased separately; its cost will start from a thousand rubles.

Electric drill for excavation work: advantages of modern devices

You have to use a variety of equipment in your garden. To plant trees or build a fence, the owner will need an electric excavation drill. This device is simple in design and has high performance. You just need to choose the right device, and the work will take less physical effort and time.

general information

Before going to the store to buy such a device, you should find out what an electric drill for excavation work is and how it generally works.

Most models have a special frame as the main structural element. It has two handles, and also has an electric motor, complemented by a gearbox.

The latter is necessary to increase torque when using the device.

There are many criteria for choosing an electric drill

During work, the unit must be held by two people at the same time. When the gearbox shaft rotates, torque is transmitted to the screw auger.

Thanks to him, it becomes possible to perform a variety of earthworks. How much you have to spend on purchasing equipment largely depends on its characteristics.

The most important are:

• dimensions;
• power;
• terms of Use.

The range of such devices on the Russian market is small, which is explained by the limited scope of their use. But in fact, an electric drill is a fairly universal device.

The choice in favor of a specific type must be made by the consumer based on the type of soil prevailing on the site.

In addition to it, you can purchase a variety of attachments that manufacturers offer for different surfaces.

In this video you will learn more about the earthen drill:

Advantages and disadvantages

Although electric earth drills are available in stores, they are rarely used on sites. Many people refuse to buy a device because they simply do not know about its main advantages:

1. Saving physical strength. These devices are powered by electricity, making the job of drilling holes in the ground an easy task.
2. Environmental friendliness. Unlike gasoline devices, their electric counterparts do not emit exhaust gases during operation, so there is no harm to plants or the environment.
3. Silence. An electric drill does not create noise during work. Thus, its use completely eliminates discomfort for neighbors.
4. Minimum weight. Modern models are lightweight, which also gives them an advantage over gasoline devices.

The main and only disadvantage of these devices is that the drill is tied to a 220 V electrical outlet. If the site is not electrified, then it is not possible to use such equipment. Although many models are equipped with batteries, the battery energy is not enough for long-term operation of the device.

Rules of application

Typically, an electric earth drill is used to make holes for planting fruit trees or shrubs. But this device can also come in handy during construction work. It is great for creating holes where piles or other supporting elements will later be installed.

Manually creating holes in the ground is a labor-intensive task and is made more difficult by the presence of rocks and tree roots.

However, using an electric drill can solve the problem easily and quickly.

In a situation where it is necessary to drill holes in a hard-to-reach place, where it is not possible to place large equipment, such a device will significantly facilitate the process.

There are a variety of electric drills available in the market today. They differ in size from each other. They can even be used for work such as drilling a well or constructing a well. If you need a device to perform a wide range of tasks in the garden, then you can easily purchase it at any specialized store.

Nuances of choice

In order for equipment to provide high efficiency when used, it should be selected correctly, focusing on the tasks to be solved. The main points that deserve attention when choosing an electric drill are the power of the device and the equipment of the device.

It is necessary to understand that low power limits the scope of use. But buying high-power equipment is also an irrational decision, especially if it is planned to be used only occasionally in the garden. The optimal choice would be to purchase a device with a power of 1.5 kW.

If an electric drill is required to install a pile foundation or perform another labor-intensive task, then models from 2 kW and above should be considered.

The well-equipped device makes it easy to perform a variety of jobs. Such a device can be considered universal, but this leads to an increase in its cost. In specialized stores, the minimum price for such equipment is 15,000 rubles. To get a high-quality and reliable device at your disposal, you need to spend a lot of money.

Main manufacturers

Many companies produce drilling equipment for use in garden plots. In countries such as Japan, Sweden and Italy, there are many companies producing electric drills . Among Russian consumers, the most popular devices are from the following companies:

1. ECHO. This Japanese company produces a variety of products. The models are highly reliable and delight with their performance characteristics. Their feature is a fairly simple design. This eliminates frequent breakdowns and facilitates maintenance. The average price tag for devices from this manufacturer is 28,000 rubles.
2. EFCO. The Italian manufacturer offers a variety of devices for drilling operations. A special feature of the devices is their increased strength; they can easily withstand heavy loads. The devices are great for frequent use. The brand's products are offered at an average price of 29,000 rubles.
3. STIHL. The equipment of this company is well known on the Russian market. The domestic manufacturer offers a variety of devices. Its product line also includes electric drills. The models are practical and durable. They are also economical to use. The devices can be used to perform work of varying complexity and are equipped with a safe locking system. The average price for them in comparison with foreign analogues is much lower and amounts to 15,000 rubles.

By choosing a device from one of the well-known manufacturers, you can get a reliable device that will last a long time. You should not purchase equipment secondhand. The best solution is to cooperate with a dealer. You can buy really high-quality equipment from an official representative of the brand, and in this case, competent service is guaranteed.

Drilling swivel, rods and locks

At first, we recommend purchasing ready-made drill swivels and drill rods. In the manufacture of these parts, processing accuracy is very important, since the loads on these units are large.

We do not recommend making a swivel from improvised means. One slightest inaccuracy and it will fail.

If you decide to order a swivel, you will need to find a turner with a CNC machine.

For the swivel and locks you will need steel:

• Locks – 45 steel.
• Swivel – 40X.

You can download a drawing of a homemade drill swivel here: DIY swivel for drilling swivel

You can save money by purchasing ready-made units, but it will take a lot of time to find a specialist. But it's worth it - homemade parts are much cheaper than purchased ones. To get started, purchase parts for samples. Turners work better when they have drawings and templates on hand.

If you have factory samples, it will be much easier to check the quality of work. For example, if a turner made drill rods and locks, then you take factory-made and home-made parts and screw them to each other - check the quality of the thread. The match must be 100%!

Do not buy spare parts by delivery. This is necessary so as not to buy a marriage - this, unfortunately, happens. And most importantly, if you order delivery from afar, you can wait more than one month.

DIY drawings of locks at Moscow State Budgetary Institution

We recommend making threads on drill rods in a trapezoid - it is no worse than a conical one. But if you then order it from a turner, it will be more difficult to make a tapered thread. If you make or buy locks for drill rods separately, then take simple suture pipes for the rods if you are drilling no deeper than 30 meters (3.5 mm thick and an internal diameter of at least 40 mm). But a welder must weld the locks to the pipes! In vertical drilling, the loads are high.

To drill deeper than 30 meters, you need to take only thick-walled pipes with a wall of 5-6 mm. Thin rods are not suitable for great depths - they will tear.

It’s not difficult to make a simple drill yourself. The drill is made from ordinary steel. If you decide to make it from alloy, then keep in mind that it is difficult to weld! Need a welder.

Drill head drawing for download: chertyozh_bur

If there are a lot of stones at the drilling site, then buy drills from companies that are adapted for strong soils. The higher the price, the harder the alloys on the drills and the stronger the drills themselves.

Homemade winch and gear motor

When manufacturing a mini drilling rig, a “RA-1000” winch is used. You can take another one, but preferably one with a carrying capacity of at least 1 ton (or better yet, more). Some drillers install two winches, one electric and the other mechanical. In the case of a drill string wedge, it is very helpful.

To make the work easier, it is better to buy and connect two remote controls: one for reverse and engine speed, the other for the winch. This will save a lot of effort.

A motor-gearbox for drilling wells for a homemade mini drilling rig will require 60-70 revolutions per minute, with a power of 2.2 kW. Weaker will not do.

If you use a more powerful one, you will need a generator, since it will not be possible to connect to a voltage of 220 Volts. If you make a hydraulic drill with your own hands, take a motor-gearbox of the following models: 3MP 31.5/3MP 40/3MP 50.
