6. The presence of a high -quality safety coupling. In emergency situations, for example, with a sudden jamming of the storm, such a coupling will allow you to quickly disconnect the engine shaft from the cartridge. If there is no safety coupling, then the rotational moment of the drill itself when jamming will go into the hand of a person and may cause a serious injury.
