Abstract: A metal cutting insert, especially for grooving operations includes a front cutting edge and two side cutting edges disposed on a top side of the insert. Two laterally spaced, upstanding ridges are disposed on the top side, each ridge extending generally longitudinally. A chipbreaker pit is formed in the top side between the two ridges. A front portion of the pit is deeper than a rear portion of the pit and intersects the front cutting edge to form a depression therein. The pit guides a chip longitudinally rearwardly toward an edge formed by the intersection of the front and rear pit sections. The ridges converge rearwardly in the vicinity of the intersection edge to form therewith a squeezing zone which squeezes the chip. A pair of burls are upstanding on the pit front portion in the vicinity of respective ones of the ridges.
