      Grades

      • K68

        Composition: A hard, low binder content, alloyed grade WC/Co fine-grain grade.
        Application: The K68 grade has excellent abrasion resistance for machining cast irons, austenitic stainless steels, non-ferrous metals, non-metals, and as an alternative to the K313 grade on most high-temperature alloys. Use as a general-purpose grade for non-ferrous materials.

        N Non-Ferrous
        S High-Temp Alloys
      • 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.

        M Stainless Steel
        K Cast Iron
        S High-Temp Alloys
      • KC5025

        Composition: An advanced PVD-AlTiN-coated grade with a tough, ultra-fine-grain unalloyed substrate.
        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 interruptions and high feed rates.

        S High-Temp Alloys
      • KC720

        • TiN-PVD-coated carbide.
        • Particularly high-impact strength grade.
        • For all steels, stainless steels, super-alloys, and titanium.
        • First choice for difficult conditions such as interrupted cutting, unstable clamping, etc.

      • 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.

      • KCU25

        Turning Composition: An advanced PVD grade with hard AlTiN coating and fine-grain unalloyed substrate. The new and improved coating improves edge stability with wide range speed and feed capabilities.

        Turning Application: The KCU25 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 improved edge toughness for interrupted cut and high feed rates.

        Holemaking Composition: Advanced CVD TiCN-Al2O3 coating combined with a tough carbide substrate.

        Holemaking Application: First choice for steel, stainless steel, and cast iron. This grade offers adequate deformation resistance, excellent edge strength, and superior wear resistance over a wide range of machining conditions for high productivity with very good reliability.
