He knows how difficult it is to maintain a strict vertical line. The slightest deviation can lead to breakage of the drill. To avoid this problem, it is recommended to use a vertical drill holder. Such a machine is available in every locksmith workshop.
Since drilling is done on a smaller scale at home, it makes no sense to buy this device. It won’t be difficult for a craftsman to make a drill holder with his own hands.
What parts will the device consist of?
Drill holders must have the following components:
- Stanin. This is the main supporting element of the future machine.
- Stand. It is necessary for fastening the carriage with the drill and its movement.
- Movement mechanism. The most common option is a special handle. With its help, you can move the drill to the part to be drilled.
- Additional nodes. With their help you can expand the capabilities of the rack.
How to make a bed?
Homemade holders for drills must be installed on stable frames. To make this unit, you can use a steel plate 1 cm thick or a durable wooden board, the thickness of which should be at least 2 cm. A thick piece of chipboard, plywood or textolite is also suitable for this purpose. 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 frame be 200 mm and the length 500-750 mm. The main vertical stand and support should be attached to the horizontal frame using screws or screws. It is recommended to screw these machine parts from below through the frame.
Holders for drills will be stronger if their racks are additionally connected to supports with metal corners.
How is the stand 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. To prevent the drill from deflecting, and, therefore, from damaging the workpiece and breaking, it is important for the craftsman to maintain a strict vertical line in relation to the bed when making the stand. You can make a vertical guide post from a block, plywood plate, pipe or metal profile. It all depends on imagination and the availability of the necessary 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 returns to its original position after drilling. It is important that lifting the bracket with the drill is smooth and that drilling does not become tiring.
How to secure a drill?
To make a drill carriage you will need a board or steel plate. It is important that its thickness matches the thickness of the machine stand. Once the material needed for the carriage has been selected, you need to attach a power tool to it and draw a circle. Then, at the master’s discretion, holes are drilled along its inside into which the mounting clamps will be inserted.
Arrangement of additional nodes
If you add additional attachments to your homemade machine, you can use it to perform simple turning and milling technological operations, as well as drill holes at an angle. In order for these works to be accessible, the master should provide the ability to move the workpiece in a horizontal plane. This is possible using a movable horizontal barrel on which a vice is installed to hold the workpiece. The barrel is driven by rotating the handle. In order to make it at an angle, homemade 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 perform the following steps:
- Drill an axial hole on the additional rotary plate and machine stand.
- Using a protractor, drill the pivot plate at angles of 30, 45 and 60 degrees.
- Equip the rack with three holes into which the pivot plate pins will be inserted. With their help, the rotating and stationary parts of the machine will be fixed in the future.
To make a hole at the required angle, just turn the electric drill attached to the additional plate to the desired angle and fix the tool in this position using pins.
Advantages 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 his creative potential. As a result, it will be more convenient to work on a device assembled in accordance with individual requests than on a standard one manufactured at the factory.
Branded drill holder
The multi-position tool from the German company Kandil is considered by craftsmen to be 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 for drilling, sharpening, 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 is used and therefore the tool is characterized by high strength. The Kandil holder is widely used today by professional craftsmen in carpentry shops.
