Milwaukee 48-89-2740 9/16" S&D Black Oxide-Coated Drill Bit

Milwaukee 9/16" S&D Black Oxide-Coated Drill Bit

The Milwaukee 9/16" S&D Black Oxide Drill Bit is a heavy-duty accessory built for boring larger-diameter holes in wood, plastic, and metal. This Milwaukee bit combines a 9/16" cutting diameter with a Silver & Deming (S&D) reduced-shank design and a black oxide finish, giving tradespeople a dependable option for oversized holes on the jobsite. Because the S&D shank is reduced to fit standard drill chucks, this larger 9/16" bit can be run in everyday drills and drivers without the need for a specialty chuck, making it a practical addition to any drilling kit. This bit is built to help electricians, plumbers, and general contractors keep projects moving without swapping tools mid-job.

Key Features

• Trade Size: 9/16" cutting diameter drill bit sized for boring larger holes in wood, plastic, and metal materials.
• S&D Shank Design: Silver & Deming (S&D) style reduced shank fits standard 1/2" drill chucks, allowing this oversized 9/16" bit to run in common drills without a specialty chuck.
• Black Oxide Finish: the black oxide coating helps resist corrosion and reduces friction at the cutting edge, supporting longer bit life through repeated use in demanding conditions.
• Milwaukee Quality Construction: engineered under the Milwaukee brand for reliable, professional-grade drilling performance on the jobsite.
• Durable Bit Construction: engineered for demanding drilling tasks across construction, remodeling, rough-in, and general maintenance work.
