Engineered for extreme operating conditions, this 115-piece cobalt steel drill set is designed to tackle tough, work-hardened materials like stainless steel and INCONEL. The 135-degree split point eliminates drill walking for precision starts, while the heavy-duty construction ensures superior rigidity for both hand and machine drilling.

• Industrial-grade cobalt steel designed for tough, work-hardened materials including stainless steel, armor, and INCONEL.
• 135-degree split point eliminates drill walking and requires less force for faster, more precise drilling.
• Refractory cobalt material resists heat, allowing tools to run cooler and providing greater longevity.
• Straw finish adds lubricity and provides easy identification of cobalt steel.
• Heavy-duty construction with precision-ground tight tolerances for extreme operating conditions.
• Superior rigidity suitable for both hand drilling and machine drilling applications.
