Milwaukee 5/16" x 12" Aircraft Length Black Oxide Drill Bit 48-89-2773

EXTENDED REACH PRECISION FOR DEEP-HOLE DRILLING

The Milwaukee 48-89-2773 is engineered for those critical moments when a standard-length bit simply cannot reach the workpiece. At 12 inches in length, this aircraft-style bit is a staple for drilling through thick framing, reaching into recessed engine bays, or navigating complex industrial assemblies. The Thunderbolt® thick core design provides significantly higher durability compared to standard bits, resisting the side-load breakage that often plagues extended-length accessories. Coupled with a 135° split point, this bit eliminates the need for a center punch by starting on contact, ensuring your holes are placed with surgical precision even on curved or uneven surfaces.

• / 12-Inch Aircraft Length allows for deep drilling and access to hard-to-reach areas where standard bits fall short.
• / 135° Split Point Tip starts immediately on contact to prevent bit walking, providing faster and more accurate hole placement.
• / 3-Flat Secure-Grip™ Shank locks the bit firmly into the drill chuck, preventing slippage under high-torque loads.
• / Black Oxide Coating provides superior lubricity and heat resistance, extending the life of the cutting edge in metal, wood, and PVC.
• / Parabolic Flute Design efficiently clears chips and debris to keep the bit cool and prevent binding during deep-bore applications.
