Abstract: A hand machine tool includes a tool retainer that retains a tool, a motor that drives the tool retainer in a rotary motion, and a torque-controlled sliding clutch that is connected in a drivetrain between the motor and the tool retainer. The sliding clutch includes a first clutch disk, a second clutch disk, a spring and a controlling unit which can be activated manually. The second clutch disk is arranged displaceably alongside an axis limited by a stop in the direction toward the first clutch disk. Force is applied to the second clutch disk by the spring alongside the axis in the direction toward the first clutch disk. The manually activated controlling unit variably sets an axial distance between the first clutch disk and the stop, with which an engagement depth of the first clutch disk with the second clutch disk can be defined.
