      • KC9105

        composition: An innovative, highly deformation-resistant cobaltenriched
        substrate (patent pending) with a new thick multilayer
        MTCVD-TiCN-Al2O3-TiCN-TiN coating for maximum wear resistance.
        application: KC9105 is the latest addition to the KENNA PERFECT
        grades for finishing to medium machining of most steels, ferritic,
        martensitic, and PH stainless steels and cast irons The specially
        designed substrate provides a remarkable combination of deformation
        resistance and insert edge strength. The extra-thick MT-TiCN layer
        provides outstanding flank wear resistance, while the thick Al2O3
        layer offers excellent crater wear resistance and speed capability.
        A state-of-the-art post-coating treatment results in a smooth insert
        surface that reduces microchipping and build-up and improves
        workpiece surface finish.

      • KC9315

        CVD-TiN-TiON-AL2O3-TiN coated carbide
        Extremely wear resistant for cutting cast iron materials
        Particularly efficient in the upper cutting speed range

      • 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.

      • 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
      • KY4300

        An Al2O3 matrix reinforced with SiC whiskers for excellent toughness suited for machining high-temperature and ferrous alloys with a high Brinell hardness.

        S High-Temp Alloys
      • 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.
