Met on the pages of “Model construction” describe the various mechanical instruments, including an improvised bit for the drill. I have been working with a power drill brand ИЭ1202 with similar nozzles and found that they are very comfortable.
Powerful, reliable and durable motor is needed and builders of electrics, and the followers of the trace of automodelisme.
