        S High-Temp Alloys
      • KCPK10

        Composition: Advanced TiCN-Al2O3-CVD coating combined with a cobalt-enriched carbide substrate, this grade offers a balanced combination of deformation resistance and edge toughness.
        Application: KCPK10 offers outstanding abrasion and crater wear resistance for high-speed machining of steels and cast irons. Use for very high cutting speeds with low to medium feed rates.

        K Cast Iron
      • 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.

        K Cast Iron
      • KCU40

        Composition: Multilayered TiN-TiAlN-PVD coating and a tough substrate, that withstands interruptions and provides high wear resistance for long tool life.
        Application: KCU40 is the first choice for high reliability in most materials. This grade should be used at medium speeds and high feeds due to sharper edges. KCU40 covers steel, stainless steel, cast iron, and high-temperature alloys for high toughness applications under certain conditions.

        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.
