Abstract

A drill includes a housing and a motor having a drive spindle. An output spindle is capable of being rotationally driven by the drive spindle via a torque clutch. The drill further includes atangential impact mechanism for superimposing tangential impacts onto the output spindle when activated. The tangential impact mechanism includes a sleeve rotatably mounted on the output spindle, and an anvil rotatably mounted onto the output spindle. The output spindle and the sleeve are rotationally driven by a planetary gear system comprising a ring gear, a sun gear and a planetary gear which is drivingly connected between the ring gear and sun gear.
