Abstract: Disclosed is a cutting insert having a generally polygonal primary body having a primary body base connected to an opposing and similarly-shaped body face through a plurality of primary flank portions extending there between. The cutting insert further includes at least one cutting protrusion extending away from at least one of the primary flank portions, and merging therewith. The cutting protrusion includes a rake face coplanar and extending away from the adjacent primary flank portions, and an edge portion extended towards a cutting flank portion. The cutting protrusion further includes a tip flat extending between a rake front from a protrusion tip towards a rake root portion, adjacent one of the primary flank portions.

Abstract: Disclosed is a cutting insert having a generally polygonal shaped primary body including a primary body base connected to an opposing, generally parallel and similarly-shaped body face through a plurality of flank portions extending there between. The Cutting insert further includes at least one cutting protrusion merging therewith and extending away there from the primary body. The at least one cutting protrusion includes a protrusion base which is generally coplanar and merges with the primary body base. The at least one cutting protrusion further includes a rake face in a direction opposite to the protrusion base, and a protruding flank extending there between the protrusion base and the rake face. The at least one cutting protrusion further includes a tip flat extending between a rake front at a protrusion tip towards a rake root portion, adjacent the primary body.
