- Industrial-grade cobalt steel designed for tough materials including stainless steel, armor, and INCONEL.
- Refractory cobalt material resists heat, allowing tools to run cooler and last longer.
- 135-degree split point eliminates walking and drills on contact with less required force.
- Nitride black and gold straw finish adds lubricity and increases tool hardness.
- Precision ground to tight tolerances for superior accuracy and rigidity.
- Heavy-duty construction optimized for extreme operating conditions in hand or machine drilling.
- Three flats on shanks for bits above 11/64 in. ensure tighter chucking.
