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.
  • Reduced-Shank Compatibility: the S&D shank profile lets crews step up to a larger 9/16" hole size using the drill chucks they already own, cutting down on tool changeovers.

Milwaukee 48-89-2740 – Frequently Asked Questions

1) Is the Lenox 12111-10DGHS a substitute for the Milwaukee 48-89-2740 drill bit?
They are not interchangeable for the same work. The Milwaukee 48-89-2740 is a 9/16 inch black oxide coated twist bit with a Silver and Deming reduced shank, intended for boring wood, plastic, and metal in rough-in and remodeling work. The Lenox 12111-10DGHS is a 5/8 inch diamond grit bit from the D/S-10Dg series; diamond grit cuts by abrasion rather than with a cutting lip, so it suits hard abrasive materials instead of general wood and metal drilling. The diameters also differ by a sixteenth of an inch, so neither produces the other's hole size.
2) Can I use this Milwaukee 9/16 inch bit on steel, or is it only for wood?
It is rated for wood, plastic, and metal. The black oxide coating cuts friction at the cutting edge and resists corrosion, which is what makes it usable in metal as well as framing lumber. For electrical and plumbing rough-in, that means the same bit handles a stud and a steel strut or plate without a changeover.
3) What size hole does Milwaukee 48-89-2740 drill?
A 9/16 inch hole. That is the cutting diameter of the bit; the shank behind it is stepped down to the S&D profile so it still chucks in a common drill. Useful size for pulling cable or running small-diameter conduit and fasteners through framing.
4) Should I use an S&D twist bit or a self-feed/auger bit for boring 9/16 inch holes through framing?
Pick by material. An S&D twist bit like the Milwaukee 48-89-2740 is the choice when the hole may run through wood, plastic, or metal, or through mixed material such as a plate with a nail plate or steel stud behind it. A wood auger or self-feed bit pulls itself through lumber faster but will not survive metal. Crews doing rough-in through steel studs want the S&D twist bit.
5) Which bit runs in a standard 1/2 inch drill chuck?
The Milwaukee 48-89-2740 uses a Silver and Deming reduced shank, which steps the shank down so a 9/16 inch bit still seats in a standard 1/2 inch drill chuck - no specialty chuck or adapter needed. The Lenox 12111-10DGHS is a 5/8 inch diamond grit bit in the D/S-10Dg series; verify its shank against your chuck capacity before ordering it as an alternative, since shank style drives what drill it can be run in.
6) Is this a single bit or part of a set?
Milwaukee 48-89-2740 is a single 9/16 inch bit, ordered on its own. There is one size offered under this part number, so if you need a range of S&D diameters you order each size separately.
7) Does the black oxide coating on this Milwaukee bit matter for a bit kept in a service truck?
It helps. Black oxide resists corrosion, which is the practical concern for a bit that lives in a damp van or a job box, and it also reduces friction at the cutting edge during the cut. It is a surface treatment, so it wears at the tip over time and does not change the 9/16 inch cutting diameter.
