The end (2) of the tool (1) insertible in the mounting in the drive unit has at least one groove (4) in two regions (B3, B4) for receiving additional male members of the tool mounting. The tool has one end which can be form-fitted into a mounting in the drive unit. This insertion end has a first region (B1) which is conically tapered in the machining direction, followed in this direction by a second region (B2) with a peripheral groove (5), adjoining a third region (B3) conically tapered in the machining direction, and a cylindrical fourth region (B4). The insertion end has at least two grooves (3) extending over the first, second and third regions in the tool length direction. The mounting has an opening which is conically tapered in the machining direction, at least one catch extending into the opening, and at least two male members which are received by the length direction grooves in the insertion end. |
