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: An advanced multilayer AlTiN-AlTiSiN/TiSiN PVD coating over a very deformation- P resistant unalloyed carbide substrate. The new coating improves wear resistance with a Si-enhanced M hard outlayer and increased edge stability achieved by a low stress baselayer. The gold outlayer KCU10B provides better used edge identification. K Application: The KCU10B grade is ideal for finishing to general machining of most workpiece N materials at a wide range of speed and feed capabilities. Excellent for machining most steels, stainless steels, cast irons, non-ferrous materials, and high-temp alloys with improved edge toughness, notch S resistance, and higher cutting speed/feed capability. P Composition: An advanced multilayer AlTiN-AlTiSiN/TiSiN PVD coating and fine-grain unalloyed substrate. The new coating improves wear resistance with a Si-enhanced hard outlayer and increased M edge stability achieved by a low stress baselayer. The gold outlayer provides better used edge KCU25B identification. K N Application: The KCU25B grade is ideal for general machining of most steels, stainless steels, high-temp alloys, titanium, irons, and non-ferrous materials in a wide range of speeds and feeds with S improved edge toughness for interrupted cuts and high feed rates. PVD-Coated Carbide Grades Composition: A PVD TiB2 coating over a very deformation-resistant unalloyed substrate. Application: Designed for roughing, semi-finishing, and finishing of free machining (hypoeutectic KC5410 <12.2% Si) aluminum, aluminum alloys, and magnesium alloys. The TiB2 coating is harder than TiN and TiAlN coatings and has an extremely smooth surface, resulting in reduced surface friction, speedy chip flow, and outstanding wear resistance. Built-up edge is prevented because this coating has a very N low affinity for aluminum. The substrate is unalloyed and fine grained and offers sharp edges, smooth surfaces, and excellent thermal deformation resistance and edge integrity. Inserts with a ground periphery are polished before coating and have a sharp edge. Molded inserts have a light hone. P Composition: An advanced PVD-AlTiN coated, fine-grained tungsten carbide grade. M K KCS10 Application: The KCS10 grade is specifically engineered for the productive machining of high-temp alloys. The fine-grained tungsten carbide substrate has excellent toughness and deformation resistance N while the advanced PVD coating allows metalcutting speeds double those of conventional PVD-coated cutting tools. S H P M Composition: An advanced PVD-AlTiN-coated grade with a tough, ultra-fine-grain unalloyed substrate. KC5025 K Application: For general-purpose machining of most steels, stainless steels, high-temp alloys, titanium, irons, and non-ferrous materials. Speeds may vary from low to medium and will handle N interruptions and high feed rates. S kennametal.com A56
