Metallics NHSD11 – Frequently Asked Questions
1) What size is a number 11 twist drill, and what is it used for?
Number 11 is a wire gauge drill size, 0.191 inch, which sits between 3/16 and 13/64 inch. Electricians reach for wire gauge sizes like this for machine screw clearance and tap drill work in sheet metal, boxes, and strut, where a fractional bit would be either loose or tight. The Metallics NHSD11 is that size in a high speed steel twist drill, 3-1/2 inches long overall.
2) How many bits come in the Metallics NHSD11 drill pack?
Ten bits per pack, supplied in a pouch rather than an index case or individual sleeve. If you stock bits by the drawer for a service van or an MRO crib, the pouch is the whole package, so plan on transferring them into your own index if you want them organized by size.
3) Is high speed steel the right bit for drilling steel boxes and strut, or do I need cobalt or carbide?
High speed steel, which is what the Metallics NHSD11 is, handles mild steel boxes, enclosures, strut, and aluminum fine at moderate RPM with a little cutting oil. Step up to cobalt when you are cutting stainless or hardened plate, and to carbide tipped or a masonry bit for concrete and block. HSS twist drills also resharpen, so a dull one is not scrap.
4) What is the exact part number to reorder the Metallics number 11 high speed drill?
Order it as Metallics NHSD11. That number covers the 10 piece pouch of number 11 high speed twist drills at 3-1/2 inches, and it is the single catalog designation for the item, so there are no length or finish options to specify.
