Metallics NHSD21E – Frequently Asked Questions
1) Is the Metallics NHSD21E drill bit long enough to bore through a wall or joist for electrical runs?
The NHSD21E is a 21 inch high-speed twist drill bit, so it reaches through stacked framing members, top plates, and standard stud bays without an extension. The description gives two figures for it, 21 inches and 3-1/4 inches, so map those to overall length and the second dimension on the bit before committing it to a drill with limited clearance.
2) Does the Metallics NHSD21E come as a single bit or in a multi-bit set?
One bit per order. The NHSD21E ships as a single piece in a pouch, not as a boxed set, so if you are stocking several van kits or need more than one diameter you order each bit separately.
3) Is this Metallics bit a bellhanger or installer bit for fishing wire, or a plain twist bit?
It is a high-speed twist drill bit, 21 inches long. Twist geometry over that length suits boring clean through framing and plate stock. If your job calls for pulling wire back through the hole, that is a bellhanger style bit with a hole through the shank near the tip, which is a different tool, so confirm which one the drawing or your foreman is asking for.
4) What does the black oxide finish on this Metallics twist drill bit actually do for me?
Black oxide on the NHSD21E is a surface treatment over the high-speed steel. It holds cutting oil better and slows surface rust, which matters on a long bit that spends its life in a pouch in a truck. It is not a coating that changes the bit's rated use, so treat it as a plain HSS twist bit for wood, and keep it lubricated in metal.
