Tool device

The invention relates to a tool device which is suitable for use with an， in particular hand-held， machine tool， having a drive device moving， in particular in oscillating fashion， about a drive axis. The tool device has a connection device which allows it to be fastened on a machine tool such that its drive axis and an axis of rotation of the tool substantially coincide. The connection device， for absorbing drive power， has at least two drive-surface regions， which are spaced apart from said axis of rotation of the tool and each have a multiplicity of surface-area points. Planes tangential to said surface-area points are inclined in relation to an axial plane which encloses the axis of rotation of the tool. Furthermore， said tangential planes are inclined in relation to a radial plane which extends perpendicularly to the axis of rotation of the tool. This means that the torque introduced into the tool device by the machine tool， via the drive device， is reliably absorbed.
