Safety Braking Device

A safety brake device for a power tool for braking a machining tool driven by means of a drive unit via an output unit including an output shaft, comprising:

• a decoupling device, configured to decouple the output unit from the drive unit during a braking operation thereby reducing at least one of a rotational mass and rotational energy to be braked of the output unit;
• and
• at least one brake device comprising at least one first brake device part and one second brake device part, wherein the first brake device part is arranged on the output shaft of the output unit so as to allow essentially no relative rotation, and wherein the second brake device part is configured to allow essentially no relative rotation with respect to the power tool, and the first brake device part and the second brake device part are configured to interact mechanically with one another during a braking operation and in such a way to stop rotation of the output unit,
• wherein the first brake device part of the brake device is embodied in one piece with the decoupling device.
