Abstract
A clamping shank for a tool for clamping the tool into a rotary driving clamping device is proposed. The clamping shank comprises a circular shank portion and a pentagonal shank portion adjoining the circular shank portion. Four contiguous side faces of the pentagonal shank portion each form an angle of 90° to each other in a plane perpendicular to the longitudinal axis of the clamping shank. A fifth side face of the pentagonal shank portion forms in said plane angles of greater than 90° with each of the adjacent side faces of the pentagonal shank portion.
