In the workshop and garage, it is often necessary to drill a hole or to clean the surface of a part, which is quite problematic to get with a standard power tool. And in this case, a flexible drive (or shaft) is useful, which is able to bend in the right direction.
Using this device, it is possible to transmit torque to a cartridge with a nozzle, which is not fixed directly to the drill motor. In terms of design, the flexible drive is a steel cable in a metal or rubber "sheath."
At one end of the shaft there is a shank that is mounted in the drill chuck, and at the other end there is a universal holder for various nozzles (drills, mills, etc.). Using a flexible drive for an electric drill and interchangeable nozzles for it, you can process surfaces or drill small holes in hard-to-reach places. However, it needs a reliable mount that you can do with your own hands.
Making a homemade flexible shaft nozzle
Making a homemade adapter for a flexible shaft for mounting on an electric drill is very simple. To do this, weld together the two lower halves of the clamps and the steel plate. Then the upper halves are screwed. One clamp is put on the body of the electric drill, and the second on the sleeve of the shaft end of the flexible shaft. This ensures a rigid connection of all elements.
Using this device you can drill holes, screw and unscrew screws, screws and screws, as well as clean and grind various wooden or metal surfaces. The advantage of using a flexible actuator for an electric drill is the reduction in arm load.
