ABSTRACT:
A tool bit has an axially extending shank section (1) to be inserted into a chuck in a manually-operated tool. The tool bit has an axially extending working section extending from the shank section. In the end region of the shank section remote from the working section there are first faces (2) acting in the axial direction and second faces (3) acting in the circumferential direction. In addition, the shank section (1) has entrainment faces (4a) spaced axially from the first and second faces toward the working section. The entrainment faces (4a) are located radially outwardly from the first and second faces (2, 3). The entrainment faces (4a) are part of grooves formed by a profiled section of the shank section and the grooves are open in the axial direction toward the first and second faces. The entrainment faces (4a) are radially spaced outwardly from the outer surface of the part of the shank section containing the first and second faces, so that they are able to transmit larger torques.
