Abstract
A cutting insert for chipforming machining of metal workpieces comprises opposed top and bottom surfaces and a peripheral wall extending therebetween. The insert has cutting edges at the juncture between the peripheral wall and at least the top surface and the peripheral wall. A land area and a chip breaker groove are located along the edges. The chip breaker groove comprises a pair of concave end depressions and a series of concave intermediate depressions disposed between the end depressions. The portions of the cutting edge disposed along the end depressions are straight and longer than portions of the cutting edge disposed along the intermediate depressions, the latter being wavy in shape.
