Abstract

A coated cutting insert for metal machining, in particular of short chipping materials, includes a tungsten carbide-based substrate with a binder phase enriched surface zone having at least one rake face and at least one clearance face intersecting to form a cutting edge. The binder phase enriched surface zone is at least partly missing on the rake face including at least a part of the surface extending from the cutting edge. As a result, an optimum combination of edge strength and wear resistance has been achieved.
