The cutting portion has an annular portion, one or more cutting elements which are disposed on a first end of the annular portion, and an insertion element which is disposed on the annular portion at an end that is remote from the cutting elements. The insertion element has at least one slit-shaped clearance with a cross-slit and a connecting slit, where the cross-slit is arranged perpendicularly in relation to the axis of rotation and is connected by way of the connecting slit to an upper edge of the insertion element.
