        composition: A CVD tri-phase coating on an extra-strong, cobalt-enriched
        alloyed substrate.
        application: Designed for heavy cutting of low-, medium-, and high-carbon
        steels, medium hardness alloy and tool steels, stainless steels, and some
        high-temperature alloys. Excellent thermal and mechanical shock resistance
        makes grade KC850 ideally suited for difficult drilling applications.
        Used in inserts for Kendex/Metcut drill bodies.

        Composition: A tough cobalt-enriched carbide grade with a newly designed multilayer MTCVD-TiCN-Al2O3 coating with superior interlayer adhesion.
        Application: Best general-purpose turning grade for most steels and ferritic and martensitic stainless steels. The substrate design ensures adequate deformation resistance with excellent insert edge strength. Coating layers offer good wear resistance over a wide range of machining conditions and the post-coat treatment minimises microchipping and improves coating adhesion to substrate leading to long tool life and improved workpiece finishes.
