Metallics NHSD31E – Frequently Asked Questions
1) What size is the Metallics NHSD31E drill bit, and what is it used for?
The NHSD31E is a high-speed twist drill bit stated as 31 inches and 2-3/4 inches, in a black oxide finish. The 31 inch length is the kind of bit electricians reach for when they need to drill through multiple studs, plates, or joist bays in a single pass from one side of a wall or ceiling cavity, rather than opening it up. It ships as a single piece.
2) Does the Metallics NHSD31E come as a single bit or a multi-pack?
One bit per order. The NHSD31E is sold as a single piece in a pouch, so if you are stocking a van or a shop crib and want spares on hand, order the quantity you need rather than expecting a set.
3) Is a 31 inch twist drill bit the right choice for boring through framing, or should I use an auger bit?
A long high-speed twist bit like the NHSD31E is aimed at reaching deep into a cavity, running through multiple framing members on one setup. An auger bit self-feeds and clears chips faster in soft wood, so it is quicker for repetitive single-stud holes. Where you need length and a bit that handles mixed material rather than maximum wood feed rate, the 31 inch twist bit is the one to take.
4) What does the black oxide finish on the NHSD31E do for me?
Black oxide on a high-speed steel twist bit cuts friction and gives some corrosion resistance, which matters on a bit this long because a 31 inch flute spends a lot of time in contact with the hole while chips are evacuating. It is a surface treatment, not a coating that changes the cutting geometry.
