FIELD: metal working in machine engineering, namely broaching in broaching machine tools. SUBSTANCE: chuck for gripping broaches includes bushing arranged on body of chuck and spring-loaded in axial direction, fixing member joined with bushing and sleeve secured to body and provided with slits on its end. Bushing is split one and it passes through said slits. Fixing member is in the form of cylindrical collet whose end surfaces are provided with slits arranged by staggered fashion.
