    WU20PD

    WU20PD

    Composition: With a multilayered PVD TiN-TiAlN coating, a high-quality, sub-micron, carbide substrate and a state-of-the-art surface condition, this grade gives the highest level of wear resistance at high cutting speeds.
    Application: First choice for alloyed and high-alloyed steels and cast irons. A state-of-the-art surface condition enables superior chip evacuation even when MQL is applied.

    Features and benefits

    • Flat bottom drill with through coolant.
    • Application specific SC Drills design to reduce the number of operations when: 1) a flat bottom hole is needed, eliminating the needs of an additional SC End Mill; 2) is necessary the preparation on an inclined or curved surface.
    • Four-margin land design to improve hole straightness and roundness. Increased stability even in crossing holes operations.
    • Creates full flat bottom holes.
    • Two grades to cover the majority of the workpiece materials.
