    KCK10A

    Composition: Multilayered PVD AlTiN-based coated submicron grain carbide with superior surface finish.
    Application: First choice for cast iron. This grade utilizes a newly developed coating combined with a state-of-the-art surface condition to offer extraordinary wear resistance in abrasive materials at elevated cutting conditions with improved performance consistency.

    Features and benefits

    • HPR point thinning provides excellent self-centering capabilities along with low-thrust, enabling maximum hole straightness.
    • 4 margin lands are deal for cross holes and inclined exits, proving maximum stability.
    • Drills holes 5X its diameter, making it ideal for deep-hole applications.
    • AlTiN/AlTiSiN multi-layer coating withstands abrasive and thermal loads to increase tool life.
    • Patented corner radius enables long tool life and excellent hole quality by avoiding workpiece chipping during evacuation.
    • HA shank design reduces vibration and provides increased stability, reducing the risk of breakage. All shanks are Minimum Quantity Lubrication (MQL) ready and fulfill the DIN 6535 and 69090-03 requirements.
