        S High-Temp Alloys
        K Cast Iron
        M Stainless Steel
        N Non-Ferrous
      • KC7215
        KC7215

        Composition: PVD TiAlN coated fine-grain carbide.
        Application: Best suited for machining of alloyed steel and cast iron. This grade offers reliable performance at intermediate cutting conditions.

        P Steel
        K Cast Iron
      • KC7815

        Multi-Layered MT-CVD TiCN-Al203 coating
        Designed for indexable drilling of alloyed steels and some cast irons
        Superior performance when drilling ferrous steels at elevated speeds
        Expect 100% improvement in tool life versus competitive grades
        Use KC7815 in outboard pockets, KC7140 in inboard pockets for optimum performance with DRILL-FIX bodies
        Geometry: GD with honed negative land provides added strength

        P Steel
        K Cast Iron
      • KCPK10
        KCPK10

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

        S High-Temp Alloys
        K Cast Iron
        M Stainless Steel
        N Non-Ferrous
      • KCU25
        KCU25

        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.
        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 cuts and high feed rates.
