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.
