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 P Composition: A multilayered coating with moderately thick MTCVD TiCN-Al2O3 layers over a highly deformation-resistant carbide substrate. K KCK05 Application: Designed for high-speed machining of gray and ductile irons. The substrate and coating architecture together with post-coat treatment ensure a tremendous tool life advantage, especially when cutting higher tensile strength ductile and gray irons where workpiece size consistency and reliability of tool life are critical. Excellent both in continuous cuts and varied depths of cut. P Composition: A multilayered coating with thick MTCVD TiCN-Al2O3 layers applied over a carbide substrate specifically engineered for cast irons. K KCK15 Application: Delivers consistent performance in high-speed machining of gray and ductile irons. The substrate design permits the insert to stay in the cut for a long time at high speeds with minimum deformation. The thick CVD coating and post-coat treatment provide superior wear resistance ensuring long and consistent tool life. Can be applied both in continuous and lightly interrupted cuts. P Composition: A specially toughened MTCVD TICN-Al2O3 coating over a wear-resistant substrate. K KCK20 Application: Specifically engineered to maximize coating adhesion and edge strength making this CVD-Coated Carbide Grades grade ideal in wet interrupted cutting of gray and ductile irons. It can be used in a wide range of applications from finishing to roughing to maximize productivity wherever strength and reliability are needed. P Composition: A multilayer MTCVD TiCN-Al2O3 coated carbide grade. M KCM15B Application: An excellent finishing to medium machining grade for austenitic stainless steels at higher speeds that covers a broad range of steel applications in the P20–P25 range. KCM15B in combination with unique geometries has been designed to resist depth-of-cut notching and minimize burr formation. The post-coat treatment reduces coating stresses, improves coating adhesion, minimizes microchipping and edge build-up, and improves workpiece finish. P M Composition: A multilayer MTCVD TiCN-Al2O3-TiOCN coated carbide grade. KCM25B Application: This CVD-coated grade is designed for general-purpose machining of austenitic stainless steels at moderate speeds and feeds. This grade offers an extraordinary combination of toughness, built-up edge resistance, and wear resistance in stainless steel applications. Composition: A specially engineered cobalt-enriched carbide grade with thick MTCVD TiCN-Al2O3- P TiOCN coating for maximum wear resistance. KCP10B Application: An excellent finishing to medium machining grade for a variety of workpiece materials, K including most steels, ferritic, martensitic and PH stainless steels, and cast irons. The cobalt-enriched substrate offers a balanced combination of deformation resistance and edge toughness, while the thick coating layers offer outstanding abrasion resistance and crater wear resistance for high-speed machining. Smooth coating provides resistance to edge build-up and microchipping and produces excellent surface finishes. A57 kennametal.com
