Milwaukee 48-89-2776 Black Oxide Aircraft Drill Bit

Product Description

The MILWAUKEE 48-89-2776 is a black oxide aircraft-length drill bit designed for extra reach and deep drilling in metal, wood, and PVC. The 135-degree split point tip starts on contact, delivering a precise entry and eliminating walking for fast, accurate holes. The 3-flat Secure-Grip shank locks firmly in the drill chuck to prevent slipping during high-torque applications. The THUNDERBOLT web construction extends bit life and improves drilling speed. This bit is sold individually and is a standard tool for electricians, plumbers, HVAC technicians, and general trade professionals who need extended reach in tight or deep installation scenarios.

Aircraft-length drill bits are used where standard-length bits cannot reach — drilling through wall studs, floor joists, deep structural members, or stacked materials. The reduced shank diameter allows use in 3/8-inch chucks, making this bit compatible with a wide range of corded and cordless drills already on the job site. Common applications include wire and pipe routing, anchor hole drilling, and fabrication work in metal and PVC. The black oxide coating reduces friction and resists corrosion, extending service life in field conditions.

Designed for use in standard 3/8-inch keyed or keyless drill chucks; suitable for drilling metal, wood, and PVC in residential and light commercial trade applications.

Installation Notes

This bit is installed and operated by licensed trade professionals including electricians, plumbers, and HVAC technicians. Ensure the drill is powered off and the chuck is fully tightened on the 3-flat shank before use. Wear appropriate eye protection when drilling metal or PVC. Do not exceed the drill manufacturer's recommended RPM for the bit diameter and material being drilled.
