ISO/ANSI CARBIDE INSERTS GRADES AND GRADES DESCRIPTIONS P Steel M Stainless Steel Coatings provide high-speed K Cast Iron capability and are engineered for N Non-Ferrous finishing to light roughing. S High-Temp Alloys H Hardened Materials TURNING wear toughness resistance Coating Grade Description 05 10 15 20 25 30 35 40 45 Composition: A tough cobalt-enriched carbide grade with an advanced multilayer MT TiCN-Al2O3 CVD P coating with gold TiN outer layer on flank for improved wear identification. KCP25C Application: Best general-purpose turning grade for most steels and ferritic and martensitic stainless K steels. The substrate design provides an excellent combination of deformation resistance and insert CVD-Coated Carbide Grades edge strength. Coating layers offer superior wear resistance enabling increased speeds and productivity compared to other P25 grades. A targeted post-coat treatment minimizes microchipping and enables improved part finishes while retaining the bright gold color on the flank so that used/unused cutting edges can clearly be identified. P M Composition: A tough carbide grade with a thin MTCVD TiCN-Al2O3-TiOCN coating. KCP40B Application: For heavy roughing of carbon, alloy, and stainless steels. The substrate-coating combination provides unbelievable toughness and operational security allowing high metal removal rates even the in most demanding interrupted cuts. Composition: A low content PcBN grade with a proprietary binder and a PVD TiN/TiAlN/TiN coating for added wear resistance and enhanced wear identification. KBH10B Application: Designed for the precision machining of hardened steels (>45 HRC). It can be effectively applied on bearing steels, hot and cold work tool steels, high speed steels, die steels, case hardened steels, carburised and nitrided irons, and some hard coatings. Available in a multi-tip format with a wide range of edge preparations, insert styles, and wiper geometries. H Composition: A medium-low content PcBN grade with a proprietary binder and a PVD TiN/TiAlN/TiN PVD coated PcBN coating for added wear resistance and enhanced wear identification. KBH20B Application: KBH20B is the ideal PcBN hard turning grade for continuous to lightly interrupted cutting applications. The structure, as well as the different edge preparations, enable repeatable workpiece tolerances, excellent surface finishes, and surface integrity. Typical applications are case-hardened steel components such as gears, shafts, and other drive-train components. H Composition: A low content PcBN grade with a PVD TiN/AlTiN coating for added wear resistance. KBH20 Application: KBH20 is the ideal PcBN hard turning grade for continuous to lightly interrupted cutting applications. The structure, as well as the different edge preparations, enable repeatable workpiece tolerances, excellent surface finishes, and surface integrity. Typical applications are case-hardened steel components such as gears, shafts, and other drive-train components. H kennametal.com A58
