Abstract
An angle grinder includes a housing, a drive unit configured to drive a usage tool, a sensor device configured to provide a rotation parameter, and a control unit configured to evaluate the rotation parameter to detect a clamped state of the usage tool. The sensor device has a yaw rate sensor configured to provide the rotation parameter in accordance with a rotational movement of the housing. The control unit triggers a safety mode in accordance with the rotation parameter or throttles the rotational speed and/or torque of the drive unit.
