Engineered for extreme operating conditions, this industrial-grade 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 straw finish provides enhanced lubricity and heat resistance for extended tool life.

• Industrial-grade cobalt steel construction 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 on contact.
• Refractory cobalt material resists high heat, allowing tools to run cooler and last longer under heavy use.
• Straw finish provides added lubricity and serves as a quick visual identifier for cobalt steel.
• Precision ground to tight tolerances with heavy-duty construction for superior rigidity in both hand and machine drilling.
• Includes 13 pieces ranging from 1/16 in. to 1/4 in. sizes.
