The most common drilling machine can be considered the one made from an ordinary or electric drill. In such a machine, the drill can be placed either permanently or made removable. In the first case, the power button can be moved to the drilling machine for greater convenience; in the second, the drill can be removed and used as a separate tool.
Components for a homemade drilling machine:
- Drill;
- Base;
- Rack;
- Drill mount;
- Feeding mechanism.
Drilling machine for the home workshop.
The base (bed) for a homemade drilling machine can be made of hard wood, chipboard or furniture board, but it is better to use a channel, metal plate or brand. To ensure the stability of the structure and obtain a good result, the frame must be made massive so that it can compensate for vibration from drilling. The size for wooden satin is 600x600x30 mm, metal - 500x500x15 mm. There must be mounting holes on the base of the machine so that it can be mounted on a workbench.
The stand for the drilling machine can be made from timber, round or square steel pipe. You can also use an old frame of a photographic enlarger, an old school microscope or another device of a similar configuration that has a large mass and high strength.
The drill is secured using clamps or brackets. It is better to use a bracket with a central hole, this will allow you to achieve better results when drilling.
Homemade drilling machine with your own hands.
The device of the drill feed mechanism on the machine.
Using this mechanism, the drill can move vertically along the stand, it can be:
- Spring;
- Articulated;
- Similar to a screw jack.
Depending on the chosen mechanism, you will need to make a stand.
Photo diagrams and drawings show the main types of designs of homemade drilling machines on which a drill is used.

Homemade drilling machine from a steering rack.
The steering rack from a car is a fairly massive device, so the frame for it must be massive and attached to the workbench. All connections on such a machine are made by welding.
Homemade drilling machine from a steering rack.
The thickness of the base should be about 5 mm; it can be welded from channels. The drain on which the steering rack is attached should be 7–8 cm higher. It is attached through the eyes of the steering column.
Since such a homemade machine becomes massive, it is better to place the control unit separately from the drill.
Video of a homemade drilling machine based on a steering rack from a car.
The procedure for assembling such a homemade machine:
- Preparation of parts;
- Installing the stand on the frame;
- Assembling the moving device;
- Installing the device on a rack;
- Drill installation.
All joints must be securely fastened, preferably by welding. If guides are used, then you need to make sure that there is no transverse play. For greater convenience, such a machine can be equipped with a vice for fixing the workpiece for drilling.
In stores you can also find racks ready for drilling. When purchasing, you should pay attention to the dimensions of its frame and weight. Often, inexpensive designs are only suitable for drilling thin plywood.

If you don’t have time to study drawings and various options for rack designs, then we invite you to watch an informative video about creating a very functional mechanism that can satisfy the needs of most home craftsmen.
The result of the work will be a stand like this with an original cable drive of the carriage
Homemade drilling machine based on an asynchronous motor.
You can replace a drill in a homemade machine with an asynchronous motor, for example from an old washing machine. The manufacturing process for such a machine is complex, so it is better if it is done by a specialist with experience in turning and milling, and assembling electrical circuits.

Design advantages
Machines for drilling deep holes assembled using an electric drill are distinguished by a range of operational advantages:
- optimal compactness and low weight of the structure;
- Possibility to carry and use batteries;
- obtaining high-quality and accurate hole parameters;
- quick assembly and dismantling of equipment without wasting time;
- performing various works and processing all materials.
For repairs and home maintenance, a machine will be enough, but for a garage and larger-scale procedures it is better to choose a different type of device.
How to make a drilling machine for printed circuit boards with your own hands.
To manufacture a drilling machine for printing circuit boards, a low-power device drive is required. As a lever, you can use a mechanism from a photo cutter or a soldering iron. Illumination of the drilling site can be done using an LED flashlight. In general, this machine is rich in the flight of creative thoughts.

Electric drill
The power tools market offers the buyer a wide range of drills, both domestic and imported. The products of domestic enterprises occupy a small segment compared to the gushing flow of electrical goods from China. Imported equipment is mainly represented by licensed models from well-known manufacturers.
It should be noted that the vast majority of power tools are high quality products, with rare exceptions.
Drills that are designed only for drilling without any additional impact devices are suitable for a drilling machine. Inserting a hammer drill into a machine is a great luxury, so for power equipment it will be enough to install a drill with a minimum of options - such as:
- adjustment of the number of revolutions;
- reverse;
- power button lock.
