Metallics NHSD28E – Frequently Asked Questions
1) What size is the Metallics NHSD28E high-speed twist drill bit?
The NHSD28E is a high-speed steel twist drill bit stated as 28 inches and 2-7/8 inches, with a black oxide finish. Use the 28 inch overall figure when you are checking whether it will reach through a stud bay or joist run, and the 2-7/8 inch figure for the cutting dimension the hole has to match.
2) What is a 28 inch black oxide twist drill bit used for on an electrical rough-in?
A 28 inch twist bit is an electrician's boring bit for running cable through framing, top plates, and multiple studs or joists without repositioning the drill. The NHSD28E is high-speed steel with a black oxide finish, which cuts heat buildup and corrosion on long wood bores. For masonry or concrete you need a carbide-tipped hammer bit instead, not a high-speed steel twist bit.
3) Is the NHSD28E drill bit sold singly or in a multi-pack?
One bit per order. The NHSD28E ships as a single piece in a pouch, so if you are drilling a long run and want a spare on the truck, order two.
