ABSTRACT:
A cutting tool, preferably in the form of a cutting insert of hard material, having a narrow land area or ledge along the cutting edge, forming a shallow recessed groove promoting the formation of a false cutting tip build-up during use of the cutting tool, the cutting tip build-up resulting from the transfer of material from the chip to the ledge surface. The cutting tool of the invention enhances and favors the formation of a cutting tip build-up by providing the shallow recessed groove with a width which is a function of the cut taken by the cutting tool in a workpiece such that the chip removed from the workpiece during a cutting operation bridges the recessed groove.
