    Abstract: Disclosed is a machine tool having a spindle driven by a drive device, the spindle having a receiving device on its free end for a tool or a tool holder, an input part being provided in the drive train of the drive device, the input part transferring a torque having a defined play in the direction of rotation via drivers to an output part which is joined in a rotationally fixed manner to the spindle, while a torque acting from the spindle in the direction of the drive device and exceeding a torque on the input side is supported on the housing of the machine tool via clamping surfaces on the periphery of the output part, via clamping elements and via a locking ring having a hollow cylindrical surface. The output part is a driving profile having two or more axially parallel planes, of which a first part acts as clamping surfaces and a second part acts as driving surfaces which cooperate with the drivers of the input part.

    Abstract: A hand-held power tool protective device (10a-d) for a hand-held power tool (12a-d) with a drive unit and a tool (26a-d) includes an operating element (14a-d, 16a-d) which can actuate an electrical switch for activating the drive unit and a shut-off unit (18a-d) have a shut-off mechanism (24a-d). The shut-off unit (18a-d) brings about a shut-off during a deactivation of the operating element (14a-d, 16a-d) and therefore, a deactivation of the drive unit via the at least one shut-off means (24a-d). An emergency shut-off unit (28a-d) enables an emergency shut-off of an operation of the tool (26a-d) when the operating element (14a-d, 16a-d) is activated. The shut-off unit (18a-d) and the emergency shut-off unit (28a-d) are at least partially formed integrally.
