TOP DRILL FLAT with Through Coolant

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.
