WORKING TOOL FOR HAND MACHINE

The invention relates to a tool device (11)， in particular for machining a workpiece， for holding in a hand-held power tool (211)， which can be operated in such a way that the tool device can be rotated about an output shaft of a tool-holding device (213)， said tool device having at least one connecting device (13)， which can be detachably connected to an output shaft of the hand-held power tool (211)， wherein the connecting device (13) can be fastened to the tool-holding device (213) in such a way that a drive axis (A) of the output shaft and a tool axis of rotation (a) of the tool device (11) substantially coincide， wherein the connecting device (13) has a cut-out (17). According to the invention， the connecting device (13) has at least one clamping wing (19)， which at least partly bounds the cut-out (17) in the radial direction of the tool axis of rotation (a) and which is bounded substantially in the direction radial to the tool axis of rotation (a) by a first bounding edge (21)， which lies on a first， in particular minimal， bounding circle (23) around the tool axis of rotation (a)， wherein the clamping wing (19) extends at least substantially along a plane orthogonal to the tool axis of rotation (a).
