Metallics NHSDC7 – Frequently Asked Questions
1) What is the Metallics part number for this 7 inch black oxide twist drill?
Order it as Metallics NHSDC7. That is both the model and the manufacturer part number for the 7 inch overall, 3-5/8 inch flute black oxide high-speed twist drill bit.
2) Why choose a 7 inch long twist bit instead of a standard jobber length bit?
The extra length is what you buy it for. With 7 inches overall and only 3-5/8 inches of that fluted, the NHSDC7 gives you reach through a stud bay, a joist, or behind a box while keeping the cutting section short, which is how electrical runs get drilled where a jobber-length bit cannot reach the work.
3) Is the Metallics NHSDC7 drill bit sold individually or in a set?
Single bit, one piece per pouch. If you need multiple sizes on the truck you will be ordering each bit separately rather than buying an indexed set.
4) Does the black oxide finish on the Metallics NHSDC7 matter for what I am drilling?
Black oxide on a high-speed steel bit adds surface lubricity and corrosion resistance, which is why these are the common choice for steel, wood, and general construction drilling rather than a bright-finish bit. The NHSDC7 is a black oxide HSS twist bit.
