Grades

  • 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.

  • KC5025

    Composition: An advanced PVD-AlTiN-coated grade with a tough, ultra-fine-grain unalloyed substrate.
    Application: For general-purpose machining of most steels, stainless steels, high-temp alloys, titanium, irons, and non-ferrous materials. Speeds may vary from low to medium and will handle interruptions and high feed rates.

  • KC720

    • TiN-PVD-coated carbide.
    • Particularly high-impact strength grade.
    • For all steels, stainless steels, super-alloys, and titanium.
    • First choice for difficult conditions such as interrupted cutting, unstable clamping, etc.
