摘要

The cutter (1) has radially-projecting cutters distributed around its edges, which extend axially. A release body (6) that is free of cutters or sharp edges is arranged at the free end of the cutter. The diameter of the release body is larger than that of the cutter. The cutter preferably has a pin (5) at its free end, to which the release body is fixed. The end of the release body further from the cutters is preferably curved convexly.
