Milwaukee 7/16" x 12" Black Oxide Aircraft Length Drill Bit 48-89-2775

EXTENDED REACH PRECISION FOR DEEP-HOLE DRILLING APPLICATIONS

When standard jobber length bits fall short, the Milwaukee 7/16" x 12" Black Oxide Aircraft Drill Bit provides the critical extension required for deep-cavity drilling and hard-to-reach framing. Engineered with a heavy-duty Thunderbolt® web, this bit is designed to withstand the lateral stresses of extended-length drilling while maintaining a consistent feed rate. The parabolic flute geometry is a mechanical advantage for professionals, facilitating rapid chip evacuation to prevent heat buildup and binding in deep holes. Finished with a black oxide treatment for superior lubricity and corrosion resistance, this bit ensures a high professional ROI through extended tool life and consistent performance across metal, wood, and PVC materials.

• / 12-Inch Aircraft Length: Delivers the necessary reach for drilling through thick structural members or into recessed areas where standard bits cannot access.
• / 135° Split Point Tip: Engineered to bite into material immediately upon contact, preventing bit walking and ensuring precision hole placement without the need for a center punch.
• / 3-Flat Secure-Grip™ Shank: Features a reduced diameter design that fits 3/8" chucks while providing three flat sides to eliminate bit slippage under high-torque loads.
• / Thunderbolt® Web & Parabolic Flute: Increases the structural strength of the bit while clearing debris faster to keep the cutting edge cool during continuous use.
