Metallics HSSC13E – Frequently Asked Questions
1) What size hole does the Metallics HSSC13E drill bit make, and what is it commonly used for?
The HSSC13E cuts a 17/64 inch hole. That is the standard tap-drill size ahead of a 5/16-18 thread, so it is the bit electricians reach for when drilling steel strut, channel, panel enclosures, or angle iron that will be tapped for 5/16-18 machine screws or bolts.
2) Will a cobalt drill bit like the Metallics HSSC13E hold up in stainless steel?
Yes. Cobalt tooling keeps its hardness at the higher temperatures you generate in stainless, hardened plate, and cast iron, which is where plain high speed steel bits burn off their edge. Run it slower with steady pressure and cutting fluid, and let the bit cut rather than pushing it.
3) What does the 135 degree split point on this Metallics bit do for me?
A 135 degree split point is a flatter, self-centering tip. It starts on its own without a center punch and resists walking on round stock or slick painted steel, and the split relieves the web so it begins cutting immediately instead of skating. For drilling steel it is the point geometry you want over the older 118 degree general-purpose tip.
4) How deep can this 4-1/8 inch drill bit actually drill?
Overall length is 4-1/8 inches, which is a jobber-length bit, and the overall figure includes the shank held in the chuck. Usable flute depth is well short of that, so for drilling through deep channel runs, stacked plate, or boring through a stud bay you need an extension-length or aircraft-length bit instead.
5) Does the Metallics HSSC13E come as a single bit or a set?
It is sold one bit per pouch, a single 17/64 inch cobalt bit rather than an index or assortment. If you are stocking a van or a shop crib and want a range of tap-drill sizes, order each diameter separately.
6) What is the yellow coating on this cobalt drill bit?
The YLW in the description refers to the bit's gold-yellow finish, which is how cobalt bits are normally distinguished on sight from bright-finish high speed steel. Treat it as an identification cue at the toolbox, not as a wear coating you have to protect.
