摘要 PCT No. PCT/EP93/03504 Sec. 371 Date Jun. 22, 1995 Sec. 102(e) Date Jun. 22, 1995 PCT Filed Dec. 10, 1993 PCT Pub. No. WO94/14575 PCT Pub. Date Jul. 7, 1994A tool, particularly a torque-transmitting tool, such as a screwdriver or a screwdriver bit, having a shaft and a working region. In order advantageously to take up peak torques with such a tool, a damping region of lower hardness or lower torsion-bar constant than the working region is provided, associated with the shaft. For this purpose, the damping region can be subsequently annealed or have a different composition of material. The latter is preferably provided in the case of a tool of sintered metal.
