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. As a Silver & Deming (S&D) style bit, it features a reduced-diameter shank that lets the full 7/8" cutting diameter fit into standard 1/2" drill chucks, giving professionals access to larger hole sizes without needing a specialty chuck adapter. 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.

Milwaukee 48-89-2742 – Frequently Asked Questions

1) Will a 7/8 inch Milwaukee Silver & Deming bit fit in a 1/2 inch drill chuck?
Yes. The Milwaukee 48-89-2750 is a Silver & Deming style bit, meaning the shank is stepped down below the 7/8 inch cutting diameter so it seats in a standard 1/2 inch chuck. No adapter or oversized chuck is needed to bore the full 7/8 inch hole.
2) Is the Lenox 12111-10DGHS 5/8-inch bit a substitute for the Milwaukee 48-89-2742 5/8-inch S&D bit?
No. Both are 5/8 inch, but they cut in completely different ways. The Milwaukee 48-89-2742 is a Silver and Deming black oxide twist bit with a reduced shank that fits a standard 1/2 inch chuck, intended for boring metal, wood and other job-site stock. The Lenox 12111-10DGHS is a diamond grit bit in the D/S-10Dg series, which grinds rather than cuts with flutes and is aimed at hard abrasive material. If you are drilling framing lumber or steel stock, stay with the Milwaukee S&D bit; swapping in a diamond grit bit of the same diameter will not give you the same hole in those materials.
3) What sizes does the Milwaukee S&D black oxide drill bit come in?
Two diameters: 5/8 inch, ordered as Milwaukee 48-89-2742, and 7/8 inch, ordered as 48-89-2750. Both are reduced-shank Silver & Deming bits with the same black oxide finish.
4) Can I drill steel with the Milwaukee 48-89-2750, or is it a wood bit?
It handles both. Milwaukee lists this S&D bit for metal, wood and other tough job-site materials, including structural steel drilling, metal fabrication, carpentry, and plumbing or electrical rough-in hole boring. The black oxide finish cuts friction and heat buildup on longer runs in metal.
5) Do I need a special drill to run a 7/8 inch Milwaukee S&D bit?
No specialty chuck is required, which is the point of the reduced shank. Any drill or driver with a standard 1/2 inch chuck will hold it. For a 7/8 inch hole in steel, use a drill with enough torque and a low speed setting, and brace it, since large-diameter bits grab.
6) What does the black oxide finish actually do on a drill bit?
On this Milwaukee S&D bit the black oxide coating resists corrosion and reduces friction and heat during extended drilling, which helps the bit hold an edge longer between sharpenings. It is a surface treatment, not a carbide or diamond cutting edge, so it is aimed at general metal and wood work rather than abrasive masonry or tile.
