Milwaukee 48-89-2773 Black Oxide Aircraft Drill Bit

Product Description

The MILWAUKEE 48-89-2773 is a black oxide aircraft-length drill bit built for extra reach and deep drilling in metal, wood, and PVC. At 12 inches in length, it gives technicians and tradespeople access to tight or deep drilling locations where standard-length bits fall short. The 135-degree split point tip starts on contact to prevent walking and deliver precise, clean holes. The THUNDERBOLT web construction extends bit life and supports faster drilling speeds. This bit is sold individually and suited for professionals who need consistent, accurate results in demanding field or shop applications.

Aircraft-length drill bits like the 48-89-2773 are used across HVAC, electrical, plumbing, and general construction trades whenever standard bit reach is insufficient. Common applications include drilling through wall studs, deep framing members, metal conduit brackets, PVC pipe, and structural steel. The reduced shank diameter makes it compatible with 3/8-inch drill chucks, so it integrates easily into standard cordless or corded drills already on the job. It is well suited for residential and light commercial work where repeated accurate penetrations are required in constrained or deep-access locations.

Key Features

• 135-degree split point tip starts on contact and prevents walking for accurate hole placement
• THUNDERBOLT web design provides longer service life and faster drilling performance
• 3-flat Secure-Grip shank locks the bit firmly in the chuck to prevent slipping during operation
• 12-inch aircraft length delivers extended reach for deep or hard-to-access drilling locations
• Reduced shank diameter fits standard 3/8-inch drill chucks
• Black oxide coating adds lubricity and resists corrosion for extended bit life

Compatibility

Designed for use in standard 3/8-inch keyed or keyless drill chucks on corded and cordless drills. Compatible with drilling applications in metal, wood, and PVC where aircraft-length reach is required.

Installation Notes

This bit is installed and used by HVAC technicians, electricians, plumbers, and general construction tradespeople. Ensure the drill is powered off and the chuck is fully released before inserting or removing the bit. Secure the 3-flat shank firmly in the chuck before operation to prevent slippage under load. Use appropriate personal protective equipment including eye protection when drilling metal or hard materials.
