Engineered for extreme operating conditions, this 60-piece cobalt steel drill set is designed to penetrate tough, work-hardened materials like stainless steel and INCONEL. The 135-degree split point eliminates drill walking for precision starts, while the heat-resistant cobalt construction ensures long-lasting performance.

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