      Grades

      • KB1340

        Composition: A high CBN content, solid PcBN insert having multiple cutting edges.
        Application: Applied in roughing to finishing of fully pearlitic gray cast iron, chilled irons, high-chrome alloyed steels, and heavy cuts in hardened steels (>45 HRC). 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
      • KY1310
      • KY1320

        composition: An uncoated, advanced, silicon nitride grade
        application: High-speed roughing to finishing of gray cast iron.
        The KY1320 grade, with better wear resistance, is an ideal compliment to
        the KY3500 grade.

      • KY1540

        composition: The KY1540 ceramic is the latest and most advanced
        sialon material ever developed.
        application: Combines excellent wear properties, fracture toughness,
        and thermal shock resistance for general purpose to finish machining
        of high-temperature alloys. Provides superior depth-of-cut notch
        resistance as compared to whisker ceramics.

        S High-Temp Alloys
      • KY1615

        Composition: An advanced Alumina/TiC black ceramic grade.
        Application: Great combination of toughness and wear resistance; used for machining alloy steels, tool steels, and stainless steels to 60 HRC (653 HB). It is also applied in finish turning and boring of cast irons.

        H Hardened Materials
      • KY3400

        composition: CVD-coated pure silicon nitride grade.
        application: Excellent combination of toughness and edge wear
        resistance; used for general purpose machining of gray cast irons
        and ductile or nodular cast irons.

      • KY3500

        A ceramic cutting material based on micro-grain Si3N4 primarily for use in light to general machining of gray cast iron and ferritic ductile cast iron. Dry machining is preferred while using this grade.

        K Cast Iron
      • KYHK15B

        Composition: A PVD coated mixed aluminum oxide composite ceramic (Al2O3) with embedded fine-grained titanium carbonitride (TiCN).
        Application: KYHK15B is suitable for turning hardened steels (45 HRC–60 HRC), finishing of cast irons and high temperature alloys. This advanced ceramic offers maximum edge strength and excellent wear resistance by achieving performance to compete with CBN.

        S High-Temp Alloys
        H Hardened Materials
        K Cast Iron
      • KYK10

        Composition: An advanced SiAlON ceramic grade.
        Application: Provides maximum wear resistance. Used for high-speed continuous turning of gray cast iron, including through scale. To be used for varying cast iron machinability.

        K Cast Iron
      • KYK25

        Composition: Pure silicon nitride ceramic with an alumina CVD coating.
        Application: Excellent combination of toughness and edge wear resistance. Used for general purpose machining of gray, ductile, or nodular cast irons. To be used for varying cast iron machinability.

        K Cast Iron
      • KYK35

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

      • KYS25

        Composition: SiAlON ceramic with a multi-layered alumina-TiCN CVD coating.
        Application: Compliments the KYS30 grade when machining high-temp and nickel-based alloys and cast materials with high Brinell hardness. This advanced CVD coating provides excellent chemical and depth-of-cut notch resistance compared to whisker ceramics.

        S High-Temp Alloys
      • KYS30

        KYS30™ is the latest in the line of α/βSiAlON grades for general purpose to finish machining of high-temperature alloys. This grade provides excellent wear characteristics, with better toughness and thermal shock resistance than whisker ceramics. KYS30 also gives improved thermal stability.
