Abstract: A machine tool with a tool, wherein the tool is connectable with the aid of a tool fitting to the machine tool, the machine tool has a motor for generating a torque, and wherein the torque is transferrable to the tool fitting with the aid of a power train of the machine tool. A play is provided in the power train, wherein a setpoint current for the motor of the machine tool can be specified with a regularly alternating sign, wherein a frequency for the change in the sign of the motor setpoint current lies in a range from 7 to 60 Hertz. A method for operating the machine tool, wherein a motor setpoint current is predetermined with a frequency in a range of 7 to 60 Hertz, so that a torque is transmitted in different directions of rotation from the motor to the tool fitting of the machine tool and a jammed tool can be released from a borehole.

Abstract: The hand-held power tool (1) includes a housing (8), which has a first housing element (9) and a second housing element (10), wherein the first housing element (9) and the second housing element (10) are decoupled from one another and are movable relative to one another. The hand-held power tool (1) furthermore includes a tool holder (2) and a motor (4) for rotational and/or percussive driving of the tool holder (2). Furthermore, the hand-held power tool (1) has a magnetic field sensor (16) for detecting a spacing (L) between the first housing element (9) and the second housing element (10). Moreover, the hand-held power tool (1) includes a control device (18) for setting a motor speed of the motor (4) in accordance with the detected spacing (L).
