  • Cutting tool comprising a cutting head and a holding shank connected thereto
    Patent number: 4718799
    Abstract: The cutting tool comprises a cutting head and a holding shank and, for transferring the torque introduced on the cutting head during machining, faces are provided in a recess of the bearing surface of the holding shank on which engage the stop faces of the cutting head. A fixed connection between the cutting head and the holding shank is brought about by a threaded pin screwed into a tapped hole on the holding shank and which projects into a conical blind hole on the cutting head. As the torque is transferred in the vicinity of the bearing surface, the threaded pin is only loaded to the extent that there is a clearance-free connection between the cutting head and the holding shank.
