To drill or tighten self-tapping screws in hard-to-reach places that cannot be reached with a drill, you can use a homemade bevel gear. It is more maneuverable, and also allows you to reduce the rotation speed of the cartridge, thereby increasing the tightening force. This allows it to be used as a wrench.
Materials:
- Gearbox from a broken angle grinder;
- bit holder.
The manufacturing process of an angular gearbox for a drill
It is necessary to remove its gearbox from a broken angle grinder. It disassembles to remove the anchor.
The removed rotor is sawn in half. You need to knock the core out of it, leaving only the shaft.
The rotor is reassembled with half of the shaft freed.
Its spindle needs to be sharpened in order to fit a bit holder or drill chuck.
A standard handle from an angle grinder is installed on the gearbox. Its shaft is clamped in the drill chuck. The device is now ready for use.
With its help, you can reach a hard-to-reach place to tighten a self-tapping screw or drill a hole.The gearbox also increases the torque, so it can be used to do things for which the power of a drill is not enough.
