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.
