Beschreibung
Zusammenfassung:	A toolholder is provided for a machine tool having a magazine containing several toolholders from which a selected toolholder can be taken by means of an arm and introduced in a working position in a rotating receiving means of the machine tool. An arm with a holding part that can be rotated via a pivot bearing in the direction of the shaft of the receiving means, is applied to the toolholder. In order to prevent the rotatably disposed toolholder from being carried along in its rotation during introduction into the spindle of the machine tool by the form-fitting coupling means of the spindle, without said coupling means engaging with the toolholder, braking means are provided which, during the introduction of the toolholder into the rotating receiving means, increase the frictional connection between the holding piece and the toolholder.
