Abstract (en)
[origin: US4776406A] A motor-driven hand drill includes a housing, in which between a motor and a drill receptacle, a safety coupling for limiting a torque, applied to a drill, is positioned. For specific conditions, for example for drilling in armoring iron, the torque applied to the drill must be increased. The drill is provided with an electro-magnetic device which is operatively connected to the safety coupling to adjust the limiting torque applied to the drill. The magnetic device is actuated by means of a pushbutton positioned in the same gripping region as the pushbutton for actuating an electric motor of the drill to switch the same on and off.
