Abstract

A cutting insert for use in a cutting tool has upper, lower and side surfaces and at least one cutting edge formed at an intersection of the upper surface with the side surface thereof. A rake face of the insert is formed with an undulated chip forming groove extending along the cutting edge and comprising a succession of alternating depressed and raised portions. Each raised portion of the chip forming groove is formed with a truncated top portion of a width which is substantially less than a distance between two adjacent truncated top portions. The depressed and raised portions preferably extend, in the direction perpendicular to the cutting edge, along the entire width of the chip forming groove.
