Engineered from industrial-grade cobalt steel, these heavy-duty drill bits are designed to tackle tough, work-hardened materials like stainless steel and Inconel. The 135-degree split point eliminates walking for precise, on-contact drilling, while the nitride black and gold treatment ensures increased hardness and tool longevity.

• 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.
