ABSTRACT:
A drill chuck is rotatably driven by a drill spindle, on which the drill chuck is mounted by a plurality of radial lugs so as to prevent relative rotation, these lugs engaging in catch recesses in the drill chuck, which allow axial free play of the drill chuck on the drill spindle, unless prevented by adjusting a shift member mounted adjustably on the drill chuck without contact with and with axial clearance from the drill spindle. The lugs are rigidly connected with the drill spindle and lie axially against adjacent opposing shift member surfaces on both sides of the drill chuck. According to the rotary position of a shift member the lugs press directly on the adjacent shift member surfaces preventing axial free play of the drill chuck on the drill spindle and transmitting the drilling force or they lie opposite indentations in the shift member with clearance from the shift member surface so as to allow axial motion free play. As a result during drilling the shift member does not bear the force of the drilling.
