Each front cutting edge is interrupted by at least two chip splitting grooves, such that the line of intersection of the front cutting edge with the interrupting chip splitting grooves includes outer crests, each being located on an imaginary convex curve, at least two inner troughs, and curve parts, extending from one respective trough to one respective axially closest crest.
