Abstract
A safety brake device for a power tool includes a decoupling device, configured to decouple an output unit from a drive unit during a braking operation thereby reducing at least one of a rotational mass and rotational energy of the output unit, and a brake device with a first brake device part and a second brake device part. The first brake device part is arranged on the output unit so as to allow essentially no relative rotation, and the second brake device part is configured to allow essentially no relative rotation with respect to the power tool. The first brake device part and the second brake device part are configured to interact mechanically with one another during a braking operation to stop rotation of the output unit. The first brake device part of the brake device is embodied in one piece with the decoupling device.
