Device for vertical drilling with a do-it-yourself drill
Externally, such devices are racks assembled from several parts with screws. The lower part serves as a support. It is a metal platform capable of holding the upper structure and the drill stably. There are screws in the support, with the help of which the stand is fixed to the working table. A cylindrical bar is attached to the supporting platform. the stand itself, located perpendicular to the table. Above the bar is equipped with a fixture for fixing the movable bracket. Its clamping flanges allow the tool to be held securely. Also, the attachment for a drill for vertical drilling is equipped with a drive handle, due to which the lifting and lowering of the bearing bracket is carried out. And as an addition, such racks can be equipped with drilling depth stops and vice.
How to make a vertical stand at home?
It is recommended to use components of old machine tools, welding equipment and building assembly profiles as components. First of all, a functional part is made with runners along which the drill will move. For this, furniture fittings can also be used. Next, a platform is formed on which a device for vertical drilling with a drill will stand. With your own hands, this part can be made from a piece of pipe, on which the base with runners will stand. You can also fix the rails on a wooden board, which is later screwed to the pipe with special hardware or clamped with brackets.
It is advisable to fix the pipe itself to the assembly table forever, since the collapsible structure will be unreliable. Fixation can be done with self-tapping screws or by welding onto a thick metal plate. Instead of a guide arm, DIY drill attachments usually have a push-up handle that directly feeds the platform with the attached drill.
The tool is positioned so that the tip points downward perpendicular to the table. Such devices are not guided by the execution of oblique holes. Then the drill is connected to the network, and the workpiece is placed on the work site. The part should be positioned so that the point with the future hole is exactly opposite the drill. The tool is then tuned to a suitable operating mode by adjusting the torque or speed of rotation. To prevent the drill attachment from transmitting unnecessary vibrations, it is advisable to ensure the maximum possible stability of the table on which the equipment is installed before starting work. During the drilling process, the operator must carefully guide the tool to the previously marked point at the same pace. The process can only be completed if the drill is removed from the workpiece.
Vertical drill attachment
Getting a quality hole with a minimum amount of burrs and without deviation from a given direction largely depends on the tool itself, but not only. Electric hand drills require special physical handling skills from the user, which allow the tool to be strictly centered and, if necessary, changed in accordance with the current task. To facilitate the process of vertical drilling, a special attachment for the drill is designed, which rigidly fixes the device and changes its position only within a given range.
Manufacturers and prices
The most functional and reliable racks are supplied by Bosch, STAYER and Profi. Such equipment is distinguished by high-quality construction materials, high performance parameters and the ability to work with a wide range of drill models. But the cost of such devices is rather big. on average, are 3-4 thousand rubles. In the assortments of Russian manufacturers “Enkor”, “Caliber” and “Superintendent” you can find a more affordable attachment for a drill costing 1-1.5 thousand. The price tag reduction almost does not affect the operating parameters, but the quality of metal and components will be lower.
Types of rack
To some extent, such devices can be considered as a bed. That is, the drill goes from the category of a hand tool to the form of a machine. Accordingly, we can talk about connecting to the mains. For example, this type of magnetic tool provides a holding force of the order of 25 kN. Such models are good in that, together with the guarantee of reliable fastening, they exclude the formation of backlash when the tool moves along the rails of the rack. A separate group includes a turning fixture for a drill, which even more resembles classic drilling machines. In this case, a two-sided grip with a vice is organized. The drill itself is fixed on one side, and the workpiece is fixed on the other. In addition to drilling, the lathe vise also allows the grinding of the workpiece. To do this, the nozzle is initially mated with the workpiece, and in the process of twisting, the master using an abrasive can correct individual edges of the workpiece.
The main characteristics of the device
There are two main parameters by which the drill stands are selected. the diameter of the fixing flange and the working length along which the tool will be moved. The diameter determines the length of the drill that can be clamped on the stand. The standard range is 45-65mm, although there are custom flanges and adapters available to expand this corridor. Most often, fasteners are designed to work with a specific tool of a certain brand. The working length, in turn, determines the path along which the movement will be carried out. If the drill attachment has a wide range of movement, this will make it possible to drill large workpieces. In fact, this value indicates the extreme depth levels of the holes. The standard stroke varies from 20 to 30 cm.But again, there are professional stands that provide the ability to move along a length of 50 cm.
There are many options for creativity. The main thing is that it is really necessary. We will separately dwell on the method of fastening the workpiece.
A machine with a vice is undoubtedly more convenient, but it is imperative to provide for the possibility of their dismantling. When processing large-sized parts, the surface of the bed must be flat.
Hand Drill Bracket
The ideal solution is to use the drill handle seat with a clamp grip. It covers the shaft bearing and is ideal for centering the entire structure.

In practice, your drill does not always have such a landing ring. In this case, the tool is secured with clamps to the body. With this method, it is important to achieve good centering of the axis of rotation, and, of course, its ideal verticality.
Homemade version of the machine from mounting plates
There are more original designs for attaching power tools. Appearance doesn’t matter. The main thing is reliability and ease of use.
Consider successful models of homemade drilling machines
These options show polar levels of technology. From primitive, collected from waste, to relatively technological, using ready-made assemblies.
How to make a machine out of a drill using materials at hand
What should the guide stand for a hand drill consist of??
Desirably with the ability to install a vise or other device holding the workpiece. At home, it is made from thick chipboard, plywood, or PCB. In the center of the axis of the installed drill, it is necessary to leave a hole with a diameter of a couple of centimeters.
Description of the necessary parts of the drilling machine from the drill
Guide vertical post
Here the developers’ imagination is unlimited. It can be a bar, plywood plate, metal profile or pipe.
The main principle in the manufacture is a strict vertical in relation to the support frame. Otherwise, the drill will deviate from the rectilinear movement, spoil the workpiece and break.
It can be of a lever type, or use a gear-rack pair. It doesn’t really matter which design you choose. It is important to observe the principle of the availability of materials, otherwise it may turn out that it is cheaper to purchase a finished product.
The mechanism of lifting and lowering is made by hands from planks
The second example of a lifting mechanism made of metal
over, not only the drill can be supplied to the workpiece. Sometimes it is more convenient to lift the product up to the drill. For example. on compact models.
Construction, assembled literally from foot materials
No assembly drawings are required, all parts are adjusted along the way. For the manufacture of the bed, a sheet of Chipboard 50×50 cm is used. As a support for the rack, we use wooden round timber.
The furniture rail can be used to make a home machine
A bar stand is screwed to the round timber, a guide is attached on the opposite side.
We attach the guide to a wooden rack
The drill holder is made from a small plank in which a suitable hole is drilled with a crown. The only part that is made using welding is a corner with a stiffener jib, with which the bracket is attached to the rail.
We make a mount for a drill from a piece of board or plywood
We assemble the lifting mechanism and check the verticality of the stroke and freedom of movement. The lift arm is made from a suitable thin block. A metal corner is installed on the round timber, the lever axis is attached to it.
The bracket with the lever is connected by a metal rod. When moving the structure up and down, no jamming occurs.
We attach the drill bracket to the rack and attach a wooden lever
Thanks to the stability of the bracket, there is no need to invent any complicated fixings. A regular clamp of a suitable size is sufficient.
Such a mount is strong enough, while you can always dismantle the drill and use it as a hand tool.
Check the drill fastening with a clamp for tightness.
We fasten the entire structure to the frame using strong metal corners. It is this element that will account for half of the drilling effort. Also, the fixing of the round timber must withstand the weight of the entire mechanism and the actual hand drill.
Wooden round timber plays the role of a counterweight and serves as the basis for attaching a rack to it with an angle grinder
The drill stand must be equipped with a return spring. Its power is selected in such a way that the arm with the drill rises smoothly without effort on the lever, and the drilling process is not tiring for the operator.
Be sure to install a drilling stand so as not to spoil the bed. Quality doesn’t matter, it’s actually a consumable. As a lot of holes form, the stand simply changes to a new one.
We put a removable lining to protect the base
The machine drills with confidence, the lever works effortlessly. Despite the simplicity of the mechanism. the hole turns out to be strictly vertical, horizontal vibration of the drill does not occur.

Metal workpieces can be drilled just as easily, the drill does not overheat and the drills remain intact. In principle, the design can be considered successful.
Additional equipment of the machine
Additional attachments allow you to use the machine for drilling holes at an angle and perform simple turning and milling technological operations.
To perform milling work on this equipment, it is necessary to ensure horizontal movement of the workpiece, for which a movable horizontal table with a vise is used to fix the workpiece. The best drive for this table will be a helical gear, which is driven by a handle.
Using a homemade drilling machine, where a hand drill acts as a working head, holes are drilled at an angle if the machine is equipped with a swivel plate with holes in an arc. A carriage and a drill are located on this plate, which can rotate on an axis, which is fixed on the machine stand. The holes on the swivel plate are made at angles of 30 °, 45 ° and 60 °. The procedure for manufacturing the mechanism:
- A hole is drilled in the center of the machine column and the swivel plate for the axis.
- Using a protractor on the swivel plate, the axes of the holes located at the most common angles are marked and the holes are drilled.
- Using axial holes on the post and plate, these two elements are aligned and fixed with bolts.
- Three holes are drilled on the stand to fix the swivel plate with pins.
The swivel plate rotates to the desired angle with the tool attached to it and is fixed with three pins connecting the fixed and swivel parts of the rack.
Machines with a swivel plate can also be used to perform simple turning work. For these operations, the drill is positioned horizontally using the swivel plate.
- Carrying frame with machine elements attached to it.
- Additional units that make the drill attachment more functional.
Self-made rack. the device is easy to install, and due to its equipping with additional nodes it turns into a universal equipment with the help of which various technological operations are performed.
DIY Making A Magnetic Drill Guide
How to make a rack at home
Component parts can be components of failed machines, construction mounting profiles, welding equipment. The first is the functional part with runners for moving the drill. Furniture fittings can be used. Then a platform is made, which is made from a piece of pipe, for example, a base with runners becomes on it. You can fix the rails on a wooden board, which is then screwed to the pipe with hardware or clamped with staples.
It is advisable to fix the pipe to the assembly table “for ages”, since the collapsible structure is unreliable. Fixation to a thick metal plate is carried out using self-tapping screws or welding. Instead of a guide lever, homemade racks usually have a pushing handle protruding upward, which feeds the platform with a fixed tool directly.
The mechanism for moving the drill vertically
Structural elements of the assembly:
- A handle with which the carriage with a drill fixed on it is brought to the surface of the workpiece.
- Spring that returns the carriage with the tool to its original position.
The mechanism can be made using two design schemes:
- The spring is connected to the handle of the machine.
- Springs are located in the grooves in the bottom of the carriage.
The first option assumes the following execution scheme:
- On the machine stand, two metal plates are fixed with screws, and an axis is installed between them, where the handle is located.
- On the other side of the rack, plates and an axis are installed, on which one end of the spring is fixed, the other end is connected to the handle.
- The pin with which the handle is connected to the carriage is located in the longitudinal groove of the carriage.
If the springs are located at the bottom of the return mechanism, the handle is also fixed with two plates and an axis that allows it to move. The springs with this scheme are located in the lower part of the grooves of the guides, which are being finalized with the help of metal corners, which limit their movement.
The principle of operation of the drilling machine, where the springs are located at the bottom of the carriage, is quite simple: going down during drilling, the carriage with a tool attached to it presses on the springs and compresses them; after the termination of this mechanical action, the springs are unclenched and raise the carriage with a drill to its original position.
The device consists of parts connected by screws. The lower part plays the role of support. This metal platform holds the top structure and the drill in a stable manner. With the help of screws in the support, the stand is fixed to the work table. The bar is perpendicular to it. On the top of the stand there is a fixture for fixing the fixed arm, whose clamping flanges securely hold the tool. The device has a drive handle that lowers and lifts the support arm. Additionally, the racks can have drilling depth stops and a vice.
The main parameters for choosing a rack are:
- Working length along which the tool moves.
- Retaining flange diameter.
Diameter specifies the length of the drill that can be clamped on the rack. The standard range is 45-65 mm, but there are specialized flanges and adapters that allow you to expand this corridor. Fasteners are more often designed to work with a specific tool.
The working length determines the travel stroke. If the fixture has a wide range of movement, this allows you to drill large workpieces. The standard stroke is 20-30 cm, but for professional racks this value reaches 50 cm.
Advantages and disadvantages
The most significant advantages of a homemade rack:
- Manufacturing is much cheaper than buying a serial model.
- The material of manufacture is trash, in fact.
- Easy to find blueprints and training videos.
- The ability to create a design option with improved performance.
- For the manufacture of some parts of the racks, you need lathes, welding and other equipment.
- Due to the imperfectly high-quality fit of structural elements, play often occurs, which is bad for the accuracy of processing with the help of a device.
- Limited functionality. With a self-made stand, it will not be possible, for example, to make holes at an angle.
- Boards at least 20mm thick.
- Small drawer with furniture rails.
- Threaded rod for moving part.
- A couple of dozen short and about three dozen long screws.
- Wood glue.
