    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
    • 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.

      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.

      K Cast Iron
    • 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.
