DescripƟon

A general purpose geometry that provides excellent chip formaƟon in most steels including free-machining, medium- and high-carbon steels. A P30 carbide substrate for improved toughness and AM480 coaƟng, a proprietary wear-resistant mulƟlayer PVD coaƟng to improve tool life. A higher rake geometry that provides excellent chip formaƟon in both stainless steels and high-temperature alloys. A tough M25 carbide substrate coated with AM485, a high heat-resistant proprietary mulƟlayer PVD coaƟng. With a general purpose geometry, the K inserts can be used in grey cast irons as well as ducƟle irons. A high wear-resistant K10 carbide substrate to improve tool life and coated with AM480, a proprietary mulƟlayer PVD coaƟng to improve resistance against tool wear. A higher rake cuƫng geometry provides excellent chip formaƟon in nonferrous materials. An M15/K15 carbide substrate paired with TiCN coaƟng for improved lubricity to resist built-up material, increasing tool life and maintaining chip formaƟon. A lower rake geometry to improve edge strength in both hardened tool steels and high-strength alloys. With a P30 carbide substrate for improved toughness and coated with AM480, a proprietary mulƟlayer PVD coaƟng to improve resistance against tool wear.
