Milwaukee 48-89-2774 Black Oxide Aircraft Drill Bit 12in

Product Description

The MILWAUKEE 48-89-2774 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 the reach needed for hard-to-access drilling applications where standard-length bits fall short. The 135-degree split point tip starts on contact for precise hole placement without walking. The Thunderbolt web construction increases durability and supports faster drilling cycles. Black oxide coating reduces friction and provides corrosion resistance for extended service life.

This aircraft-length drill bit is suited for residential and commercial jobsite work across multiple trades. It handles structural metal, wood framing, and PVC pipe drilling where extended reach into confined or deep spaces is required. The reduced shank diameter allows use in standard 3/8 inch chucks, making it compatible with common cordless and corded drills already on most job carts. The 3-flat shank design prevents bit rotation inside the chuck during high-torque drilling operations.
