Milwaukee 7/8" S&D Black Oxide Drill Bit

The Milwaukee 7/8" S&D Black Oxide Drill Bit is designed to deliver clean, accurate holes through metal, wood, and other tough materials commonly encountered on the job site.

The Black Oxide finish helps protect the bit from corrosion and reduces friction and heat buildup during extended drilling sessions, which can help extend the usable life of the bit. Backed by the Milwaukee name, this drill bit is built to stand up to repeated use in demanding professional and industrial environments, making it a practical addition to any drilling kit.
