Milwaukee 3/16″ x 12″ Aircraft Length Black Oxide Drill Bit 48-89-2771

EXTENDED REACH PRECISION FOR DEEP-HOLE DRILLING APPLICATIONS

The Milwaukee 48-89-2771 is engineered for professionals requiring extended reach without sacrificing structural integrity or hole accuracy. At 12 inches in length, this bit is specifically designed to navigate deep-cavity drilling in metal, wood, and PVC where standard jobber lengths fall short. The 135-degree split point geometry is a critical mechanical feature, providing an immediate start on contact and eliminating the tendency for the bit to walk across the workpiecea necessity when working on finished surfaces or precision layouts. The black oxide treatment provides essential lubricity to reduce heat buildup and friction, significantly extending the service life of the cutting edges during high-torque applications while offering superior corrosion resistance in harsh jobsite environments.

• / 135 Split Point Tip starts on contact to prevent walking and ensures fast, accurate hole placement.
• / 12-Inch Aircraft Length provides the necessary reach for deep drilling and hard-to-access areas.
• / 3-Flat Secure-Grip Shank prevents the bit from slipping in the chuck under high-torque loads.
• / Black Oxide Coating resists corrosion and provides lubricity for cooler operation and longer bit life.
