      Grades

      • K313

        Composition: A hard, low binder content, unalloyed WC/Co fine-grain grade.
        Application: Exceptional edge wear resistance combined with very high strength for machining titanium, cast irons, austenitic stainless steels, non-ferrous metals, non-metals, and most high-temp alloys. Superior thermal deformation and depth-of-cut notch resistance. The grain structure is well controlled for minimal pits and flaws, which contributes to long, reliable service.

        S High-Temp Alloys
        N Non-Ferrous
      • KC5010

        Composition: An advanced PVD AlTiN coating over a very deformation-resistant unalloyed carbide substrate. The new and improved coating enables speeds to be increased by 50–100%.
        Application: The KC5010 grade is ideal for finishing to general machining of most workpiece materials at higher speeds. Excellent for machining most steels, stainless steels, cast irons, non-ferrous materials, and super alloys under stable conditions. It also performs well machining hardened and short chipping materials.

        P Steel
        S High-Temp Alloys
        M Stainless Steel
      • KC5410

        • TiB2-PVD coating over a very deformation-resistant unalloyed substrate.

        • Designed for roughing, semifinishing, and finishing of free machining (hypoeutectic <12,2% Si) aluminum, aluminum alloys, and magnesium alloys.

        • High hardness and extremely smooth surface, resulting in reduced surface friction, speedy chip flow, and outstanding wear resistance.

        • Prevents built-up edge because of a very low affinity for aluminum.

        N Non-Ferrous
      • KC730

        P Steel
        S High-Temp Alloys
        M Stainless Steel
      • KC850

        composition: A CVD tri-phase coating on an extra-strong, cobalt-enriched
        alloyed substrate.
        application: Designed for heavy cutting of low-, medium-, and high-carbon
        steels, medium hardness alloy and tool steels, stainless steels, and some
        high-temperature alloys. Excellent thermal and mechanical shock resistance
        makes grade KC850 ideally suited for difficult drilling applications.
        Used in inserts for Kendex/Metcut drill bodies.

        M Stainless Steel
      • KC9010
      • KC9025
      • KC910
      • KC9110

        Composition: Specially engineered, cobalt-enriched carbide grade with thick K-MTCVD-TiCN coating layer, an Al2O3 layer of controlled grain size, and outer layers of TiCN and TiN for maximum abrasion and wear resistance for high-speed machining.
        Application: An excellent finishing to medium machining grade for a variety of workpiece materials including most steels, ferritic and martensitic stainless steels, and cast irons. A balanced combination of deformation resistance and edge toughness. The smooth coating resists built-up edge and microchipping. For rougher cutting, use the KC9125 grade.

      • KC9140

        composition. A newly engineered, tough carbide grade with an advance multi-layered TiN-MT-TiCN-Al203-TiN coating.
        Application. For heavy roughing applications of alloy steels where insert edge strength is critical. A specially designed coating ensures excellent interlayer adhesion and long tool length.

      • KC9225

        MT-CVD-TiN-TiCN-Al2O3-TiN gradient carbide
        For continuous to slightly interrupted cuts
        For universal use in boring on stainless steels
        Reduced edge build up due to micro-polished surface

      • KC9240

        Multi-layered Tin-MT-TiCN-Al2O3-TiN CVD coating over a tough, non-enriched carbide substrate
        Designed for tough boring applications at moderate speeds and feeds
        Combination of toughness, built-up edge resistance, and wear-resistance in stainless steel applications
        Excellent thermal/mechanical shock resistance makes KC9240 inserts ideally suited for even the most challenging stainless steel applications

      • KC9240NEW

        composition: A multi layered CVD coating comprised of  TiN-MT-TiCN-Al2O3-TiN coating over  a tough, non-enriched carbide substrate
        application: This CVD coated grade is designed for tough applications at moderate speeds and feeds. KC9240 inserts offer an extraordinary combination of toughness, built-up edge resistance, and wear resistance in stainless steel applicaions. Excellent thermal/mechanical shock resistance makes KC9340 inserts ideally suited for even the most challenging stainless steel applications
