ABSTRACT:
A polygon shaped cutting tip for a metal workpiece boring tool, the cutting tip having linear side edges lying in a common plane and adjacent side edges which pass tangentially into rounded corner regions. Parts of the corner regions and of the side edges serve as the primary and secondary cutting edges of the tip. A chip breaker edge is arranged at a distance in from the side edges. A chip breaker surface extends from the side edge to the chip breaker edge. The chip breaker edge includes linear sections corresponding to the linear side edges of the tip and has curved sections which correspond to the curved regions of the side edges. The arc of curvature of both the curved regions and the curved sections is the same although the arcuate length of the curved sections is greater. The chip breaker surface extends from the side edges of the corner regions inward toward and downward into the tip at an acute angle where it intersects the chip breaker edges.
