Everyone who 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 a nuisance, it is recommended to use a vertical drill holder. Such a machine is available in every locksmith's workshop.
Since at home drilling is performed on a smaller scale, it makes no sense to buy this device. It is not difficult for a craftsman to make a holder for a drill with their own hands.
What parts will the device consist of?
Holders for drills must have the following components:
- Bed. This is the main supporting element of the future machine.
- Rack. It is necessary for fixing the carriage with a drill and its movement.
- Movement mechanism. The most common option is a special pen. With its help, you can move the drill to the drilled part.
- Additional nodes. With their help, you can expand the capabilities of the rack.
How to make a bed?
Home-made holders for drills must be installed on stable beds. For the manufacture of this unit, you can use a steel plate 1 cm thick or a strong wooden board, the thickness of which should be at least 2 cm. Also for this purpose a thick piece of chipboard, plywood or textolite is suitable. The massiveness of the bed 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. The main vertical stand and the support should be attached to the bed horizontally with screws or screws. It is recommended to screw on these machine parts from below through the bed.
Holders for drills will be stronger if their racks are additionally connected to the supports with metal corners.
How is the rack made?
Holders for drills must be equipped with racks. The quality of drilling operations will depend on the manufacturing quality 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 in the manufacture of the stand to observe a strict vertical with respect to the bed. You can make a guide vertical rack from a bar, plywood plate, pipe or metal profile. It all depends on the imagination and the availability of the right material.
Travel mechanism
The drill holder for vertical drilling must be equipped with a special mechanism with which you can 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 after drilling returns to its original position. It is important that the lifting of the bracket with the drill is smooth, and the drilling does not tire.
How to fix a 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, on its inside, at the discretion of the master, holes are drilled into which fixing clamps will be inserted.
Arrangement of additional nodes
If you adapt additional attachments to a homemade machine, you can perform simple turning, milling technological operations on it, as well as drill holes at an angle. In order for these works to be available, the foreman should be able to move the workpiece in a horizontal plane. This is possible using a movable horizontal barrel, on which a vice is mounted to hold the workpiece. The barrel is driven by the rotation of the handle. In order to drill holes at an angle, homemade machines are additionally equipped with special turning plates containing holes in an arc. With their help, the workpiece is fixed. To cope with this work, the master should do the following:
- Drill an axial hole on the optional pivot plate and machine stand.
- Using the protractor, drill a rotary plate at angles: 30, 45 and 60 degrees.
- Equip the rack with three holes in which the pins of the turntable will be inserted. With their help, fixing of the rotary and fixed parts of the machine will be carried out in the future.
To make a hole at the required angle, just turn the power 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 holder for a drill on their own will save a lot. In addition, the master, creating his own machine, uses creativity. As a result, it will be more convenient to work on a device assembled in accordance with individual requests than on a standard factory-made one.
Signature drill holder
The multi-position instrument of the German company Kandil among the masters is considered a very high-quality and convenient device. This product is equipped with a system that allows you to change the position of the tool. In addition to the drill, the machine provides for fixing an angle grinder (grinder). The branded holder is characterized by ease of installation and reliable fixation of tools. This machine can be used both for drilling, and for grinding, grinding and polishing work at any angle. Using a drill, holes on such a device are drilled in vertical and horizontal planes. In the manufacture of these German holders, high-quality steel and aviation aluminum are used, so the tool is characterized by high strength. The holder from Kandil is today widely used by professional craftsmen in the carpentry shops.
