Abstract: A tool device for a hand-held power tool, which can be operated such that the tool device is rotated about an output shaft of a tool-holding device, has at least one connecting device, which is detachably connected to an output shaft of the power tool. The connecting device is fastened to the tool-holding device so that a drive axis of the output shaft and a tool axis of rotation substantially coincide. The connecting device has a cut-out and at least one clamping wing, which at least partly bounds the cut-out in the radial direction of the tool axis of rotation and which is bounded substantially in the direction radial to the tool axis of rotation by a first bounding edge, which lies on a first bounding circle around the tool axis of rotation. The clamping wing extends at least substantially along a plane orthogonal to the tool axis of rotation.

Abstract: A quick clamping device for a portable power tool includes at least one rotatably drivable output shaft, at least one clamping unit, at least one operating unit, and at least one uncoupling unit. The clamping unit, for tool-free fastening of an insert tool unit to the output shaft, includes at least one movably mounted clamping element for applying clamping force to the insert tool unit in a clamping position of the clamping element. The operating unit is configured to move the clamping element into the clamping position and/or into a release position of the clamping element. In the release position, the insert tool unit can be removed from the clamping unit. The at least one uncoupling unit is configured to uncouple the operating unit from the clamping unit in accordance with the rotational speed of the output shaft.

Abstract: The invention relates to a tool device which is suitable for use with a machine tool, in particular a hand guided machine tool, having a driving device moving, in particular in an oscillating manner, around a driving axis. The tool device has an attachment device which allows it to be fastened on a machine tool such that its driving axis and an axis of rotation of the tool substantially coincide. The attachment device, for absorbing the driving force, has at least two driving area regions, which are spaced apart from said tool axis of rotation and each has a plurality of surface points. The tangent planes to said surface-area points are inclined in regard to an axial plane, which encloses the tool axis of rotation. Furthermore, said tangent planes are inclined regard to a radial plane which extends perpendicularly to the tool axis of rotation. This means that the torque introduced into the tool device by the machine tool, via the driving device, is reliably absorbed.
