Everyone who has worked with a hand drill knows how difficult it is to maintain a strict vertical. The slightest deviation can lead to breakage of the drill. To prevent such trouble, it is recommended to use a vertical holder for a drill. Such a machine is available in every locksmith shop.
Since drilling is done on a smaller scale at home, it does not make sense to buy this device. For a craftsman, it will not be difficult to make a holder for a drill with your own hands.
What parts will the fixture consist of?
Holders for drills must have the following nodes:
- Stand. This is the main supporting element of the future machine.
- Rack. It is necessary for fastening the carriage with a drill and its movement.
- Movement mechanism. by the mosta common option is a special handle. With it, you can move the drill to the part being drilled.
- Additional nodes. Use them to expand the rack's capabilities.
How to make a bed?
Homemade drill holders must be installed on stable beds. For the manufacture of this assembly, you can use a steel plate 1 cm thick or a solid wooden board, the thickness of which must be at least 2 cm. A thick piece of chipboard, plywood or textolite is also suitable for this purpose. The massiveness of the frame depends on the power of the power tool. The higher it is, the thicker the base should be. It is desirable that the width of the bed is 200 mm, and the length is 500-750 mm. To the frame, located horizontally, with the help of screws or screws, the main vertical rack and support should be attached. It is recommended to screw these machine parts from below through the bed.
Drill holders will be stronger if their racks are additionally connected to the supports with metal corners.
How is the rack made?
Drill holders must be equipped with stands. The quality of drilling work will depend on the quality of manufacturing of this unit in the future. So that the drill does not deviate, and, therefore, does not spoil the workpiece and does not break, it is important for the master to observe a strict vertical in relation to the frame when making the stand. Makethe guide vertical rack can be made of a bar, plywood plate, pipe or metal profile. It all depends on the imagination and the availability of the right material.
Movement mechanism
The drill holder for vertical drilling must be equipped with a special mechanism that can be used to move the tool. This mechanism consists of two elements:
- Handles. With its use, the drill is brought to the surface of the workpiece.
- Springs. With its help, the drill returns to its original position after drilling. It is important that the lifting of the bracket with the drill is smooth and drilling is not tiring.
How to fix the drill?
To make a carriage for a drill, you need a board or a steel plate. It is important that its thickness matches the thickness of the machine stand. After the material necessary for the carriage is selected, it is necessary to attach a power tool to it and draw a circle. Then, holes are drilled along its inside, at the discretion of the master, into which mounting clamps will be inserted.
Arrangement of additional nodes
If you adapt additional attachments to a home-made machine, you can perform simple turning, milling technological operations on it, as well as drilling holes at an angle. To make these works available, the master should be able to move the workpiece in a horizontal plane. This is possible with the help of a movable horizontal shaft, on which a vise is installed to holdblanks. The movement of the barrel is driven by the rotation of the handle. In order to drill holes at an angle, home-made machines are additionally equipped with special rotary plates containing holes in an arc. With their help, the workpieces are fixed. To cope with this work, the master should do the following:
- Drill an axial hole on the optional turntable and machine stand.
- Using a protractor, drill the turntable at 30, 45 and 60 degree angles.
- Equip the rack with three holes into which the pivot plate pins will be inserted. With their help, in the future, the rotary and fixed parts of the machine will be fixed.
To make a hole at the desired angle, just turn the electric drill attached to the additional plate to the desired angle and fix the tool in this position using the pins.
The benefits of "homemade"
Those who decide to make a drill holder on their own will save a lot. In addition, the master, creating his own machine, uses creativity. As a result, a custom-built fixture will be more comfortable to work with than a standard, factory-made one.

The multi-position tool of the German company Kandil among the masters is considered a very high quality and convenient device. This product is equippedsystem that allows you to change the position of the tool. In addition to the drill, the machine provides for fixing an angle grinder (grinder).
