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.
