Claim 0:
1. A tool device for machining a workpiece, comprising: a connector device defining a clearance and configured to be releasably connected to a tool receptacle device of a hand-held power tool such that an output axis of an output shaft of the hand-held power tool and a tool rotation axis of the tool device substantially coincide, the connector device comprising: a plurality of clamping wings extending radially inwardly at least substantially along an orthogonal plane to the tool rotation axis, each clamping wing of the plurality of clamping wings including a first delimitation edge that lies on a first delimitation circle defined around the tool rotation axis and that at least partially defines a radial extent of the clearance, wherein each clamping wing has a drive edge and a coding edge that delimit opposite circumferential ends of the clamping wing, and a distance measured along the first delimitation circle between the drive edge and the coding edge defines a respective circumferential extent of each clamping wing, wherein the clamping wings of each adjacent pair of clamping wings are spaced apart from one another by a circumferential distance defined along the first delimitation circle, and the circumferential distance is less than the respective circumferential extent of each clamping wing of the adjacent pair of clamping wings, wherein the respective circumferential extent of each clamping wing defines an angular extent of less than 900, and wherein each clamping wing is asymmetrical about every plane of symmetry defined by the radial direction and an axial direction of the tool rotation axis.
