Engineered for extra reach, these 6-inch aircraft extension drill bits are ideal for drilling into carbon, alloy, and cast iron steels. The 135-degree split point prevents walking and reduces required force, while the black oxide finish ensures cooler operation and extended tool life.

• 6 in. aircraft extension provides extra reach for deep applications
• 135-degree split point eliminates walking and drills on contact with less force
• Black oxide finish improves lubricity, allowing the drill to run cooler and last longer
• Premium high speed steel construction offers superior rigidity for hand or machine drilling
• Precision ground to tight tolerances for accurate drilling
• Optimized for drilling in carbon, alloy, and cast iron steels
