Metallics NHSDZE – Frequently Asked Questions
1) What size hole does the Metallics NHSDZE letter Z twist drill make?
The NHSDZE is a letter Z drill, which is the largest of the letter sizes at 0.413 inch diameter. That sits between the 13/32 inch (0.406) and 7/16 inch (0.4375) fractional bits, so use it when a fractional size leaves the hole either too tight or too sloppy, such as tapping clearance work in an electrical enclosure.
2) Is a letter Z bit the right size to drill for a 1/2 inch NPT tap or a 1/2 inch conduit knockout?
No on both counts. A letter Z at 0.413 inch is too small for either one, so do not substitute it. Use it where the print or the tap chart actually calls out letter Z, or where you need a clearance hole just over 13/32 inch. Ordering by letter size matters here, since 13/32 and 7/16 are the nearest fractional bits and neither drills the same hole.
3) How long is the Metallics NHSDZE twist drill, and will it reach through a deep box?
Overall length is 5-1/4 inches. That is a jobber-style length for a letter Z bit, so the flute section is only part of that total and the rest is shank held in the chuck. For drilling through strut, panel sides, or stacked plate it is fine; for reaching down inside a deep cavity past an obstruction, you want an extension-length or aircraft-length bit instead.
4) Can I use the Metallics NHSDZE high-speed twist drill in a standard cordless drill?
Yes. It is a high-speed steel twist drill with a round shank, so it chucks into any standard three-jaw keyless or keyed chuck. No SDS or quick-change adapter is involved. At 0.413 inch diameter you will want the drill in low gear and steady pressure, since larger bits stall a cordless quickly at high speed.
5) What is the Metallics NHSDZE drill bit good for, and when should I pick a step bit instead?
High-speed steel twist drills like the NHSDZE cut steel, aluminum, brass, and wood, and they are the right choice when you need a full-depth hole in solid stock. For sheet metal, a panel wall, or an enclosure side, a step bit is the better tool: a twist drill this size tends to grab and triangulate a thin-gauge hole. Keep the twist drill for thicker material and pilot-then-ream work.
6) Is the Metallics NHSDZE sold as a single bit or in a set?
One bit per unit, packaged in a pouch. If you are standardizing a truck or a shop crib on letter sizes you order each size separately rather than buying a boxed index.
7) What part number do I order for the Metallics letter Z high-speed drill?
Order Metallics NHSDZE. That single part number covers the letter Z, 5-1/4 inch high-speed twist drill supplied one per pouch; there are no finish, length, or pack variations to specify.
