                  • KC5010

                    Composition: An advanced PVD AlTiN coating over a very deformation-resistant unalloyed carbide substrate. The new and improved coating enables speeds to be increased by 50–100%.
                    Application: The KC5010 grade is ideal for finishing to general machining of most workpiece materials at higher speeds. Excellent for machining most steels, stainless steels, cast irons, non-ferrous materials, and super alloys under stable conditions. It also performs well machining hardened and short chipping materials.

                  • KC850

                    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.
