Abstract

There is described a cutting tool with improved properties for metal machining having a substrate of cemented carbide and a hard and wear resistant coating on the surface of said substrate. The coating is deposited by Physical Vapor Deposition (PVD). The coating is composed of metal nitrides in combination with alumina (Al2O3). The coating is composed of a laminar multilayered structure. The insert is further treated to have different outer layers on the rake face, and flank face respectively.
