How to make a drill from a circular disk

Details of the yamobur and features of its work

Fields of application of the garden drill:

  • planting trees, shrubs;
  • installation of posts under the fence;
  • installation of street lamps;
  • arrangement of the drainage system;
  • creation of a well;
  • drilling a well for water;
  • drilling holes for ice fishing.

Purpose – excavation of soil of the required diameter, depth by physical efforts of a person.

make, drill, circular, disk

Performance directly depends on:

  • product design;
  • which cutting element is used;
  • diameter, depth of the hole in the ground.

For a standard earth drill to make a hole up to 3 m deep and 25-30 cm in diameter, it will take about 2-3 hours.

For deeper drilling, special equipment is used in the form of drilling rigs.

The handcrafted design contains the following details:

  • A pen. It is accepted to be made of steel. Has the same diameter as the shaft. For the convenience of drilling, they are welded perpendicular to the shaft (rod) in the shape of the letter T. Rubber pads are put on both handles so that there is no friction during movement, the hands do not slip and are less tired. Minimum length – 40 cm, recommended – from 50 to 60 cm.
  • Rod or shaft. Material – shaped tube of round, square section. Diameter – 0.5 to 1 inch. It is not worth making the barbell more thick, as this will require more effort. A handle is welded on one side of the rod, on the other – a cutting part with a lance.
  • Screw (cutter head). A key element of the earth auger. Responsible for loosening the soil and pushing it to the surface. Excess soil is removed when the tool is taken out of the well. The most popular option is with two steel semicircles sharpened at the edges. The diameter is selected according to the purpose. To improve the convenience of work, the blades are made removable.
  • Scrap (peak). Made in the form of a large drill or blade. Located at the bottom in the center of the product under the blades. Specifies the direction of the shaft. In a strictly vertical position, it enters the ground. Loosens the ground in the center, making it easier for the blades to work.
  • Extension cords. These are additional nozzles or sections of the rod, with the help of which it will be possible to increase the drilling depth up to 15 m. They are fixed with screw connections. Used when needed.

For cutting elements, it is recommended to take steel as a material – this is a guarantee of a long service life of the tool.

Selection of materials

To collect blanks for the main elements of the drill, you will need:

  • For the rod. Round or square tube. Size – 2020 mm, 3535 mm.
  • For blade knives. Sheet steel 4 mm thick or saw blade from angle grinder, circular saw (optional). Below we will consider the application of each of them..
  • For the handle. Round tube. The diameter is selected according to the girth of the palm.
  • For the peak. A large diameter sharpened bar or steel strip is used. A combination of both materials is allowed.

It is better to work with metal in protective gloves and goggles..

How to make an earth drill yourself

With a little effort and clearly observing the requirements of the step-by-step instructions from the masters, you will be able to make a brace with your own hands in a matter of hours.

Instrument preparation

  • welding machine with electrodes, protective mask;
  • angle grinder with disc attachments;
  • electric or hand drill;
  • hammer;
  • sharpener;
  • vice;
  • ticks;
  • marker, tape measure;
  • compass.

For anti-corrosion protection of metal, a primer, a brush are purchased separately.

Drawing or diagram

First, it is recommended to draw a basic diagram of the future product, which will become a template and simplify the assembly process.

Here, each master makes a drill for himself, selects the size, material, type of construction, calculates the material consumption and its cost. In the process of use, the finished product can be improved.

From the saw blade

The best saw blade option is diamond. It is highly durable.

Used circular discs are also suitable. They are made from hardened steel. They have a well-sharpened edge, reliable, but they cannot be bent, so the disc is sawed in half and the two parts are set at an angle. To make the drill easier to go, side edges are additionally sharpened on a machine or manually.

Saw blade auger is more productive than others and is suitable for all types of soil.

Borax varieties for the intended purpose

Depending on the place, the areas of use have nuances in the design. Let’s analyze each of them in more detail..

Option 4. Spoon drill

The spoon drill is designed primarily for drilling wells under water with the simultaneous installation of a casing. To make it, you need to take a piece of pipe (approximately 70–100 cm) and make a slot along its length. An old drill bit can be welded in at the bottom. The peculiarities of the bore-spoon is that its attachment of the upper part to the bar is offset from the axis by about 10-15 mm. In this case, the welded drill and the rod are coaxial. Thus, when drilling, the borehole diameter will be greater than the diameter of the drill itself..

It remains to sharpen the cutting edge in the direction of rotation. The cut soil will remain inside the cylinder cavity and the drill must be periodically freed from the rock.

Hand drills can be used to drill holes in loose rocks, but this tool is not suitable in rocky terrain. Of all these options, a spiral drill can handle small stones..

Homemade drill powered Disc Sander

So, four different options for products that you can make yourself are considered. The first two are more suitable for digging holes for posts and seedlings, the last two are more “specialized” for drilling water wells. Which option suits you best – choose for yourself.

Making a barbell

A rod is a metal rod or tube to which knives and a handle are attached. Depending on the purpose for which you need a drill, you need to select the material for the manufacture of the rod..

If you plan to use a drill to dig holes for seedlings or fence posts, then trimming a pipe or metal rod from the floor to your chest (1-1.2 m) will be sufficient.

If a drill is needed to make a well, the rod will need to be upgraded. This is due to the fact that drilling must be carried out at great depths, so the system must be made with the possibility of extension. Here are some options for how you can do this:

  • cut the threads on the boom sections and splice them, if necessary, using the couplings. To prevent unauthorized unwinding, it is necessary to fix the connection with cotter pins;
  • at one end of the rod, you can weld a nut, for example, 20M, and to the other rod, a bolt 20M. It is necessary to provide for the possibility of fixing the threaded connection;
  • take small pieces of pipe slightly larger than the rod and weld them on one edge. A new rod is inserted into them and a through hole is drilled for a bolt connection..

This way you can prepare the required number of connecting sections..

The drill should enter the soil easily, so the bottom should be sharp. A more advanced version can be made by welding an old drill onto the bottom of the rod..

The handle and its features

To make a handle, you need a piece of pipe about 40 cm long.Choose a diameter such that when you grip it with your hand, you can comfortably hold it.

Before attaching the handle, squeeze the top edge of the bar in a vise to shape it into an oval shape. Weld the handle perpendicular to the rod.

The most important part in the storm is the knives. Their design will determine with what labor costs you can make holes in the ground. The material from which they will be made must be hard and resilient..

Variable cutting edges

The need to prepare blades of various sizes is due to the multitasking of such a tool. Since with the help of a drill you can build a fence, make a hole for a well, etc., for each task you need to prepare holes in the ground of a certain diameter.

Based on this, it is recommended to make the attachment of the blades removable – on a bolted connection. This will allow them to be replaced as the need arises..

For example, the cutting edge with a diameter of 9 and 12 cm is used to prepare seedling holes, for geological research, as well as to change the level of groundwater. Such blades are convenient to use if you need to lay a communications network. Another purpose is to prepare holes in the ground for garden wells.

Larger cutting edges are used for planting plants with a core root system, installing fences, building outbuildings, greenhouses, etc. Cesspools, wells are also built using this type of tool.

Any of these problems can be solved with a garden drill, but only if it is made correctly. For this, drawings are prepared, where the point of installation of the blades, handles with indicated dimensions of holes, threads, etc. will be determined..

This will save money on the purchase of a ready-made tool. In addition, this option makes it possible to implement an individual project using suitable materials and structural elements of a special sample..

Design with drawing, overview of advantages

If you have imagination and some stock of knowledge, you can use a manual garden tool for burying into the ground in order to solve various problems:

  • well construction is a popular solution today in suburban garden plots, and with the help of a garden drill, you can make a hole in the ground with the desired parameters both in depth and in diameter;
  • erection of fences from various materials, the main requirement for this is a small and medium weight of the structure;
  • geological research (soil samples are taken);
  • laying of a communication system;
  • preparation of shallow holes for planting seedlings.

The handheld garden drill has its own advantages that make it the preferred tool for the job. For example, ease of control should be highlighted, a fairly low weight that allows you to wield such a device..

Shovel drill scheme

Also, a manual garden drill saves time, since it can be used to make a hole much faster than using a shovel. Given that there are various variations of such a tool, you can perform different types of work, and without involving a large number of assistants..

A- with a recycled grain harvester auger, B – a drill with a pan-shaped container, B – with auger blades from used discs.

Thanks to its compact dimensions, the ground drilling device is easy to transport. It can be used to make holes even in hard-to-reach garden areas. And thanks to the rigidity of the structure, such a drill will cope with the root system of plants, the soil of a dense structure. Structurally, this tool consists of several main nodes:

The figure shows: 1 – handle; 2 – insert; 3 – nozzle; 4 – clutch; 5 – fasteners; 6 – plates with a blade.

Hand drill drawing

Cutting structural elements are found in different variations: auger, helical, half discs and two blades. The mounting method also varies: hand drill with removable and welded cutting edges.

How to make a garden drill with your own hands

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. Below, near the peak, the smallest are welded, higher, retreating a few centimeters – the large ones. There can be three such tiers, maximum four. The entire cutting part should not be more than 50 cm, otherwise it is very difficult to work physically.

Cutting blades can be arranged in several tiers

If a drill is needed for shallow pits – for installing poles, etc., then such a design is optimal – it has a relatively low weight, it is easy to work with it. The process of work is as follows – they lowered it into the hole, turned it several times – pulled out, poured out the soil stuck between the blades. But if you need to drill deep pits, you will be tortured to drag a small amount of soil from the depth. For such cases, a box for collecting soil is welded above the blades..

Homemade drill with soil receiver is suitable for installing poles and piles

And all these are hand-made boers. All of them are highly efficient – it is much easier to work than purchased ones..

Drill for piles TISE

In the author’s version, the TISE drill is a blade with a soil receiver and a wider folding knife, which forms an extension in the lower part of the pile. But working with such a projectile is inconvenient – a folding knife interferes greatly. Therefore, in some structures it is made removable, but in general, it is recommended to drill the pits themselves with an ordinary garden drill, and to expand it, make a separate folding knife with a land receiver. This makes work easier and faster..

A do-it-yourself drill for TISE piles is one of the options

A cut-off shovel acts as a knife here, and the land receiver is made from a herring can. The knife is fixed movably, when it is 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 cut the sides of the pit, 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 efficient. The plow-blade is made from a piece of spring, sharpened and welded to the folding structure on bolted connections.

More complex design

Dredger – from an old propane tank. The earth is collected from the bottom, because the receiver is made with a rounded bottom. It has two holes, their edges are sharpened.

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

Shovel drill

For planting plants, it makes no sense to make a serious structure. In this case, you can make a garden drill from a shovel. They choose a high-quality shovel made of good steel, apply the markings, as shown in the drawing. According to the markings, you will need to cut out two small fragments, cut the lower part in the middle to a depth of 30 cm (pictured).

Further, the edges are bent one forward, the other back, the petals formed in the lower part are bent to them. The resulting seams are welded outside and inside.


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

Making a garden drill

A garden drill 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 to be drilled. For convenience, the blades can be made removable – bolted.

Pole drill can be with an assembly rod

This is a basic design, and there are many improvements to it. But first, let’s talk about what a ground drill can be made of..

Designs and application

There are three main designs of earth drills:

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

Hand drill design

A garden drill is a very useful tool for any summer resident. It is very compact, handy and easy to use. As a rule, it is made from hard 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 holes are made by the cutting part of the device, which can be of various shapes:

  • Two-bladed;
  • In the form of half-discs;
  • Helical;
  • Auger;
  • Multi-tiered;
  • One-piece or removable.

There are models that start with small blades, and their upper part is gradually increased to larger 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 nozzles will be of the wrong diameter..

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

Let’s look at several different designs that are responsible for the efficiency and functionality of the drill:

  • Baking powder. This part consists of a pair of planes or a screw. The auger looks like a spiral, the knife is on the bar.
  • Soil receiver. This part collects soil and makes it much easier to drill holes up to 35 cm in size..
  • Shaper plow. It is located in the lower zone. This design allows you to strengthen the columnar foundation, which is very important in the construction of massive structures..
  • The auger is bolted to the handle. The length of the ready-to-use and fully assembled product is about a meter, which allows you to easily make holes up to 70 cm deep. If the hole should be of greater depth, then the structure can be extended with a tube (500 mm). This element is a part with a nut and a bolt, which are located at the ends of the pipes..

Materials and tools

In order to make a hand drill for poles, as a rule, you do not need much effort. But the master needs materials and components to create a product..

List of required parts:

  • Nut and bolt M20;
  • Discs with a diameter of 100-150 mm – 2 pieces;
  • Drill with a tip (20 mm in diameter);
  • Sections of a metal pipe: two 500 mm and one 400 mm. Wall thickness should be 3.5 mm, outer diameter – 40 mm.

The wall thickness of the metal pipe must be exactly that in order for the finished product to be durable and able to work with any, even fairly hard, soil. Discs can be taken from a circular saw or made by hand. For self-made discs, you will need sheets of metal at least 3 mm thick..

From the tools when creating a product you will need:

  • Angle Grinder;
  • hammer;
  • welding machine;
  • drill;
  • drills for metal;
  • blade sharpener.

If a drill bit is not available, it can be replaced with a taper shank drill. Its diameter must match the auger. In order to avoid injury, it is recommended to use soft bicycle handles.

Protective covering

To avoid rust on the parts of the homemade pole drill, carefully clean them with sandpaper and treat them with a primer and phosphating solution. After such processing, the finished product can be painted..

When using the device, it is necessary to disassemble it after each use and clean all connections from dust and dirt, as well as cover them with a special grease that repels water. Do not miss this moment, as proper maintenance of the tool will be a good prevention of bolt jamming and will allow it to work smoothly for a very long time..

Hand drill for pillars: DIY making

Certainly, the owner of the land plot at least once faced the need to dig holes for pillars and various supports to decorate the appearance of the site. It so happens that you need to make a narrow hole in an inconvenient place. It will be difficult to cope with a simple shovel, and you will have to take a hand drill under the posts from friends or even call a specialist who deftly controls the tool.

    Draw a circle on a sheet of metal, marking the center. This will be the blade. Next, cut this circle with an angle grinder, and then apply a cut line that runs along the mowing line of diameter. Then we apply a cut-out line, which should correspond to the circumference of the knob. The resulting disc must be divided into two parts and the holes for the wrenches must be cut.

    At the end of the pipe, which will act as a knob, we cut through an angle grinder four longitudinal mowing lines, 3-4 cm in length. After that, you need to form a tip from them with a hammer, while you need to collect the cuts at the very center of the pipe. The resulting edge must be processed by welding and made so that the knob does not clog with soil during operation..

    The next step will be to connect the wrench to the disc 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 must be equipped with a handle. This detail must be welded with the letter “T” and be sure to weld amplifiers to it in the form of a “kerchief”. The workpiece is threaded through the knob, and a hole is made through them so that you can fasten the parts with a hairpin. Several such holes need to be made in order to be able to adjust the length of the product..

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

    Ways to improve the tool

    When drilling holes, the master may encounter a large number of plant rhizomes, which are densely buried in the soil. The sharp edges of the blades will greatly facilitate the work with the drill. For ease of use, you can cut several teeth on the sloping area of ​​the blade or round off its cutting zone.

    You can improve the design and make removable cutters for the drill. 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 crank. The easiest way is to connect them with two iron plates, which are attached by welding..

    In the mounting plates, as well as in the blades, two holes must be drilled for the sides. The cutters are fixed with M6 bolts. In order for the bolts not to interfere during operation, they must be screwed in with the thread upward..

    There is another way to improve a homemade pole drill. You can enhance the efficiency of the lower end of the wrench. To do this, you need to cut out a narrow metal plate (10 × 2 cm) and grind in the form of a cone using an angle grinder, making a kind of point.

    There is no need to make cuts in the knob, turned metal plates are inserted into its end, fixed by welding and flattened. As a result, you should get a peak.

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

    A suitable drill can act as a screw, which can easily cope with wood, as well as metal. Such a tool will enter the ground much easier and will drill a hole to the desired depth without any problems..

    Builders who work in dense deep soil layers will need one piece of advice. A small flat cutter must be welded between the lance and the cutter. Thanks to this design, loosening of the earth and centering during drilling will be possible. For such a part, you will need 2 metal plates 3 × 8 cm.This trick will significantly speed up the work with the tool.

    Cutters can also be made from angle grinder discs, which are designed to work with stone. The circles need to be cut along the radius and the hole in the center should be widened according to the diameter of the wrench. The bending of the disc with the opening of the sides gives a likeness of a corkscrew or auger. It remains only to weld the part in the way described above..

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

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

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

    Hand drill for earthwork from a disc for wood

    In the warm season, most summer residents try to equip their land as well as possible. And the device of fences is not in the last place here. For such work, earth drills are used. They even drill wells for irrigation, with a high level of groundwater.

    The design of the drill for earthworks is not intricate, but it has some nuances. With an erroneous position of the blades, you can only complicate the task and make the tool inconvenient and unsuitable for work. Well, the right drill will allow you to dig holes for fence posts in a matter of minutes. Let’s see how to make it from a circular saw blade..

    Materials (edit)

    • Disc for circular woodwork, diameter – 150-250 mm;
    • Pipe (rod), diameter depends on the seat on the disk (15-32mm), length – 1.5-1.80 m;
    • Transverse pipe (for the handle), length – 500-600 mm).

    We make a drill for earthworks step by step

    The main element for this product will be a spent disc for sawing wood on a circular. Its shape is already ready, and is perfect for cutting into the ground.

    We fix it on a workbench or work table with a clamp, and make one cut of the angle grinder along the radius mowing line. Our version of the drill will be optimal in terms of functionality and the degree of complexity of manufacturing.

    Initially, circular discs are made elastic. This is necessary so that when the disc resists against the wood during sawing and heating, the disc does not break, flying apart in all directions. Heat the disc with a blowtorch or gas torch to slightly loosen the metal.

    We bend the blades obtained after sawing with an improvised tool, and insert some object into the gap between them (a wooden block, a cutter for a lathe, etc.). The bend must be calculated for your leading hand, and also take into account the position of the disc cutters, which must be directed in the direction of the drill (they must not cut into the rock, otherwise additional resistance will be created against stones, roots and other obstacles, which will complicate the operation of the tool).

    We clamp the rod-pipe in a vice or in a lathe chuck. We put a disk on it, leaving 10-15 cm below its level for cutting into the ground of the end switch of the rod.

    We weld the pipe-rod and disc by electric welding. The seam must be made on both sides, and then cleaned with a sanding disc on an angle grinder.

    The stem tip can be made from a metal plate, sharpened in the form of an arrowhead, and welded.

    We weld the transverse handle from the end of the stem opposite to the drill, adjusting it in the middle.

    Now you can safely start drilling holes for trellis or metal posts for a fence in a summer cottage!
