EXTENDED REACH AND PRECISION FOR DEEP-BORE APPLICATIONS
When standard jobber length bits fall short, the Milwaukee 3/8″ x 12″ Aircraft Length Drill Bit provides the critical extension required for drilling through thick structural members or reaching into recessed cavities. Engineered with a 135° split point, this bit eliminates walking on contact, ensuring a precision start without the need for a center punch—even on curved or hard metal surfaces. The black oxide coating is professionally applied to provide superior lubricity, which significantly reduces friction and heat buildup during deep-hole drilling in metal, wood, and PVC, ultimately extending the service life of the cutting edge.
- / 135° Split Point Tip starts on contact to prevent walking and deliver fast, accurate holes in hard materials.
- / 12-Inch Aircraft Length provides the necessary reach for deep drilling applications and obstructed work areas.
- / 3-Flat Secure-Grip™ Shank holds the bit firmly in the drill chuck to prevent slipping under high-torque loads.
- / Black Oxide Coating resists corrosion and provides lubricity to clear chips efficiently in deep-bore scenarios.
