The invention relates to a tool holder comprising a coupling piece for coupling to the chuck of a drilling or screwing machine (1), wherein the coupling piece comprises at least one body (9) that is received movably in radial direction in a carrier (6), wherein the body is movable to a position engaging onto the holes (4) arranged in the chuck (2) by a movable locking element and wherein a tool clamped in the chuck can be received inside the tool holder, wherein the locking element is movable in axial direction. Such a tool holder finds application for instance in the use of a drilling or screwing machine wherein operations are performed requiring the alternating use of two tools. An example of this is the making of screw connections, wherein holes are drilled and screws are rotated into the drilled holes. The axial movement of the locking element has the result that the actions for locking the tool holder on and releasing it from the chuck take place in the same direction as the respective movements with which the tool holder is placed on the chuck and taken therefrom. <IMAGE> |
