The chuck body 1 is provided with a conical shaft a to accommodate the quick-change clamp in the quill of the fieitstoekes. In Fütterkörper and clamping nut the Eiführungsausschnitt is ο for the tool insert sleeve 3 incorporated * About is c Extract the Werkzeugeinsatzhülse.in the Aufaahmebohrung d of the chuck body 1 inserted · Centered, the tool insert sleeve 3 in the Aufnahmebohruag d of the chuck body 1 through the konisehe surface e and the Mounting hole d itself · Pie conical surface is thus once on the tool insert and once on the chuck body 1 «blessing rotation, the tool insert sleeve 3 is secured by the leas f on the chuck body. Clamping nut 2 and the chuck body 1, through stop pin g tuned to · With that cut-c cover of clamping nut 2 and the chuck body in the open state. A quarter turn of the clamping nut 2, the tool insert sleeve 3 d in the Aufnahmeboferung and β against the conical surface of the Fratterkörpers 1 pressed, centered and clamped resulting in the following mode of operation: tool insert 3 is inserted radially into cut-out c with the tool and centered and tightened by a quarter turn of clamping nut 2 If the clamping nut is loosened as far as it will go, the tool insert can be opened with the tool to be taken out the same way "

In the embodiment shown, a drill with a Morse taper is drawn in as the tool 4. The tool insert sleeve 3 can of course also be provided with an outer cone for receiving a drill chuck or the like.
