6" Aircraft Drill Bits

Reach Further. Drill Cleaner. Built for Demanding Work.

At 6 inches long, these Aircraft Extension Drill Bits are designed for deep-reach drilling in tight or hard-to-access spaces. Built from M2 high-speed steel with a black oxide finish, they're engineered to handle the heat, torque, and repetition of heavy-duty job site use.

• 6" Length — extended reach for drilling in confined or deep-access areas
• M2 HSS — high-speed steel construction for excellent hardness and heat resistance
• 135° Split Point — self-centering tip starts on contact, no center punch needed
• Ground Flute — precision-ground for cleaner cuts and faster chip evacuation
• Extra Flexibility — engineered to flex without breaking in extended-reach applications
• Heavy Duty Web — reinforced core for added strength and durability under load
• Straight Shank — fits standard drill chucks for easy, universal use
• Black Oxide Finish — reduces friction and provides corrosion resistance

When standard-length bits can't reach, the Aircraft Drill Bit gets the job done.
