    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

    • Designed for trochoidal milling with low radial engagement and full length of cut.
    • With chip deformers for ideal chip evacuation at high surface quality.
    • Proprietary flute form reduces vibrations and improves tool life.
    • Helix angle tailored to minimize vibration and optimize tool life.
    • Front end geometry designed for maximum tool life in helical and ramping operations.
