ABSTRACT:
A boring head is retained to a connecting shaft by means of a cylindrical fastening spigot, using a retaining screw with a conical end which engages a conical transverse bore in the spigot such that the boring head is tightened by wedging effect against the connecting shaft. The fastening spigot is provided with a cylindrical transverse bore, at an approximate right angle to the conical transverse bore in the spigot, and a longitudinally displaceable drive pin is supported in the cylindrical transverse bore such that the ends penetrate, with slight play, into recesses in the connecting shaft. During the transmission of torque, the drive pin is automatically centered so that the forces developed are evenly distributed between the two ends of the drive pin, so that the device is particularly suitable for the transmission of high torques, whether of a gradually increasing or an impulse type, and is usable either with a clockwise or a counterclockwise movement.
