Abstract

A metal cutting insert comprises a top surface which is intersected by a frusto-conical edge surface to form therewith a round cutting edge. Five equidistantly spaced flat facets are formed in the edge surface. Upper ends of the facets are spaced below the cutting edge. A fixing screw secures the insert to the seat of a holder, such that two of the facets are pressed against respective flat contact areas formed on a locating surface of the holder. Each facet forms an acute angle relative to a central axis of the insert.
