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

• Industrial-grade cobalt steel designed for drilling tough, work-hardened materials including stainless steel, armor, and Inconel.
• Refractory cobalt material resists heat, allowing the tool to run cooler and extend service life.
• 135-degree split point eliminates walking and enables drilling on contact with less required force.
• Nitride black and gold straw finish adds lubricity, identifies cobalt, and increases tool hardness.
• Precision ground to tight tolerances for superior rigidity in both hand and machine drilling applications.
• Heavy-duty construction built to withstand extreme operating conditions.
