      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.


      • 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.
