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.
