Engineered for extreme operating conditions, this 15-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 faster, more precise starts, while the straw finish provides enhanced lubricity and heat resistance.

• 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 for faster, more accurate drilling on contact.
• Refractory cobalt material resists heat, allowing tools to run cooler and providing extended tool longevity.
• Straw finish adds essential lubricity and provides easy identification of cobalt steel.
• Precision-ground to tight tolerances with heavy-duty construction for superior rigidity in both hand and machine drilling.
• Designed for extreme operating conditions with high heat resistance.
