Abstract

There is proposed a screwdriver bit (1) which has at its one end a driven region (3) capable of being brought into engagement with a screw, at its opposite end a driving region (5) capable of being assigned to a driving device of a machine tool, and an intermediate region arranged between these ends and comprising a torsional zone. The screwdriver bit (1) is distinguished in that the intermediate region from the driven region (3) as far as the driving region (5) is designed as a torsion region (11), and in that the profile of the torsion region changes preferably continuously, virtually over its entire length. <IMAGE>
