Rotational broaching cutter (10) with at least nine cutting edges (1, 2) arranged on the periphery. So that the cutter can be moved axially relative to the workpiece without radial movement of the cutter, or so that, without risk of injury, the workpiece can be changed without radial movement of the cutter, it is proposed according to the invention that there be an aperture angle (3) of less than 180 DEG at least between a first and a last cutting edge, and that there be such a gap and clearance space (4) that surfaces of a workpiece (5) which are machined at least by these cutting edges can be held free of cutting edges and cutter components. <IMAGE> |
