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.

Hand machine tool

A hand-held power tool is disclosed. The power tool has a tool receptacle for holding a tool along an axis. A housing has a grip area for a first hand. The grip area has a support section for the thumb and index finger in a plane with the axis and a shaft section for gripping around on one side of the plane. A contact surface for a second hand, which is arranged facing away from the tool receptacle and on another side of the plane, is inclined between 80 degrees and 100 degrees to the plane.

Hand-held power tool

A motor-switch arrangement for a hand-held power tool includes a drive motor (), an actuating switch () with a contact plug (), and an adapter () arranged between the contact plug () and the drive motor () and having a plug connecter () cooperating with the counter-plug contact element () of the drive motor () for establishing a first electrical plug connection (a) of the adapter (), and a counter-plug connecter () electrically connected with the plug connecter () and cooperating with a plug contact element () of the contact plug () for establishing a second electrical plug connection (b) of the adapter ().
