Engineered for extreme operating conditions, this 29-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 heavy-duty construction ensures superior rigidity for both hand and machine drilling.

• Industrial-grade cobalt steel designed for drilling through tough, work-hardened materials like stainless steel, armor, and INCONEL.
• 135-degree split point eliminates drill walking and requires less force, allowing for faster, more precise drilling on contact.
• Refractory cobalt material resists heat, allowing the tool to run cooler and providing extended tool longevity.
• Precision-ground to tight tolerances with heavy-duty construction for reliable performance in extreme operating conditions.
• Straw finish provides added lubricity and serves as a quick visual identifier for cobalt steel.
• Offers superior rigidity for high-performance use in both hand and machine drilling applications.
