      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
      • KB1340

        Composition: A high CBN content, solid PCBN insert having multiple cutting edges.
        Application: Applied in roughing to finishing of fully pearlitic grey cast iron, chilled irons, high-chrome alloyed steels, sintered powdered metals, and heavy cuts in hardened steels (>45 HRC). Also use for finishing chilled cast iron and fully pearlitic cast iron. The solid PCBN insert offers better security and shock resistance compared to tipped PCBN inserts, while also enabling deeper depth-of-cut capabilities.

        K Cast Iron
      • KB1625

        Composition: A medium CBN content, PCBN tip brazed onto a carbide insert.
        Application: Designed for roughing to finishing of hardened steels (>45 HRC) where optimal surface finish is needed. It can be used in continuous to interrupted cutting of bearing steel, hot and cold work tool steels, high-speed steels, die steels, case-hardened steels, carburised and nitrided irons, and some hard coatings.

        H Hardened Materials
      • KB9640

        composition: A high CBN content, solid PCBN structure having multiple
        cutting edges and a CVD alumina coating.
        application: The KB9640 grade is applied in the roughing to semifinishing
        of fully pearlitic gray cast iron, chilled irons, high-chrome alloy
        steels, sintered powdered metals, and heavy cuts in hardened steels
        (>45 HRC). Also use for finished chilled cast iron and fully pearlitic cast
        iron. Do not apply on finishing hardened steels. The solid KB9640 also
        can be effectively applied when roughing hardened steels.

      • KCK05

        Composition: A multilayered coating with moderately thick MTCVD TiCN-Al2O3 layers over a highly deformation-resistant carbide substrate.
        Application: Designed for high-speed machining of grey and ductile irons. The substrate and coating architecture together with CW5 post-coat treatment ensure a tremendous tool life advantage, especially when cutting higher tensile strength ductile and grey irons where workpiece size consistency and reliability of tool life are critical. Excellent both in straight and varied depths of cut.

        P Steel
        K Cast Iron
      • KCK05B

        Composition: A multilayered coating with moderately thick MTCVD TiCN-Al2O3-TiOCN layers over a highly deformation-resistant carbide substrate.

        Application: Designed for high-speed machining of gray and ductile irons. The substrate and coating architecture together with CW5 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 straight and varied depths of cut.

        P Steel
        K Cast Iron
      • KCK15

        Composition: A multilayered coating with thick MTCVD TiCN-Al2O3 layers applied over a carbide substrate specifically engineered for cast irons.
        Application: Delivers consistent performance in high-speed machining of grey 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 straight and lightly interrupted cuts.

      • KCK20

        Composition: A specially toughened MTCVD-TICN-Al2O3 coating over a wear-resistant substrate.
        Application: The KCK20 grade is specifically engineered to maximise coating adhesion and edge strength making this grade ideal in wet interrupted cutting of grey and ductile irons. It can be used in a wide range of applications from finishing to roughing to maximise productivity wherever strength and reliability are needed.

        K Cast Iron
      • KM1

        Composition: Uncoated, fine grain, straight carbide grade, containing 6% cobalt.
        Application: General purpose grade for use on gray iron, aluminum, and non-ferrous
        work piece materials. Available for use with HTS-C deep drilling tools and CTR
        countersinking tools.

      • KY3500

        Composition: Pure silicon nitride grade.
        Application: Maximum toughness. Used at high feed rates for rough machining of grey cast iron, including machining through interruptions.
