    Grades

    KC643M

    KC643M

    Coated fine-grain grade with PVD multilayer (AlTiN). KC643M™ is a very thin and hard PVD coating particularly suited for cutting steel, cast iron, stainless steel (wet), and titanium (wet). This grade can be used for materials with hardness up to 52 HRC.

    Features and benefits

    • Economic solid carbide end mill with short style shanks, saving expensive carbide.
    • Not recommended for reconditioning.
    • Extremely stable cutting conditions due to short design.
    • Center cutting for plunging and ramping operations.
    • Unequal flute spacing for chatter-free machining at highest feed rates.
