Metallics HSSCN12E – Frequently Asked Questions
1) What size hole does a #12 wire gauge drill bit make?
The HSSCN12E is a #12 wire gauge size, not a fractional size. A #12 is 0.189 inches, which falls between 11/64 (0.172) and 3/16 (0.1875). Electricians reach for the number sizes when they are drilling a tap hole or a clearance hole to a screw chart rather than a fraction on a print, so confirm your print calls out a gauge number before substituting 3/16.
2) Is the Metallics HSSCN12E a cobalt drill bit, and what does the cobalt mean for drilling steel?
The HSSCN12E is a heavy-duty cobalt high-speed-steel bit. Cobalt HSS holds its edge at higher heat than plain HSS, which is what you want for stainless, hardened strut, and structural steel where a standard black-oxide bit burns up. Run it slower with steady pressure and it will outlast an HSS bit in the same hole.
3) What does the 135 degree split point on the HSSCN12E do on sheet metal and strut?
A 135 degree split point self-centers and starts cutting without a punch mark, so it won't walk on strut channel, enclosure sheet steel, or a stainless plate. The flatter 135 included angle also spreads the cutting load, which is the normal pairing with cobalt for harder material. A standard 118 degree bit usually needs a center punch first.
4) Will a 3-1/2 inch drill bit reach through what I am drilling?
Overall length on the HSSCN12E is 3-1/2 inches, which is jobber-type length for this diameter. That gives you roughly two and a half inches of usable flute after the chuck grip, so it handles strut, box walls, angle iron, and stacked plate. For drilling deep inside a wall cavity or past an obstruction you need an extension-length or aircraft-length bit instead.
5) Does the HSSCN12E have a straight shank that fits a standard drill chuck?
Straight shank, so it chucks into any standard keyed or keyless three-jaw drill or drill press. It is not a hex-shank or quick-change bit, so it will not snap into an impact driver's 1/4 inch collet.
6) How many bits come with the Metallics HSSCN12E, and how is it packaged?
One bit per pouch. It is sold as a single piece rather than an index or set, so if you are stocking a van or a maintenance crib for one repeated hole size, order the quantity you need of the same size rather than expecting assorted diameters.
7) What is the exact part number to order the Metallics #12 cobalt bit?
Order it as Metallics HSSCN12E. That single part number covers the #12 gauge, 135 degree split point, straight shank, 3-1/2 inch cobalt bit in the yellow finish. There are no finish or length options to specify.
