ABSTRACT:
A cutting insert, especially for milling cutters and the like, and which is to be mounted in a tool holder in a negative radial rake position. The insert is indexable and invertable and has a cutting edge means. The peripheral wall adjacent the cutting edge means has recesses therein which interrupt the cutting edge means. The depth of the recesses becomes shallower as the recesses extend away from the cutting edge means until the recess terminates in the peripheral wall. An insert having at least two cutting edges is described wherein the insert has at least two cutting edges and the recesses interrupting one cutting edge are staggered relative to the recesses interrupting the other cutting edge when the cutting edges are viewed in superposed relation.
