Metallics HSSC20E – Frequently Asked Questions
1) What size hole does the Metallics HSSC20E drill bit make, and how deep can it go?
The HSSC20E is a 3/8 inch diameter cobalt jobber-style bit with a 5 inch overall length, so the usable flute length is shorter than that 5 inches. For 3/8 inch anchor holes or clearance holes in steel strut, panel enclosures, and plate, it covers typical thicknesses easily. If you need to reach through deep stacked material, step up to a longer aircraft-length bit instead.
2) Will a 3/8 inch cobalt drill bit cut stainless steel and hardened plate, or do I need carbide?
Cobalt is the right choice for stainless, abrasive alloys, and work-hardening material, which is exactly what the HSSC20E is built for as a heavy-duty cobalt bit. The cobalt is alloyed through the body, so it holds its edge at the higher heat stainless generates and it can be resharpened. Truly hardened plate or masonry is carbide territory, not this bit.
3) What does the 135 degree split point on this Metallics bit actually do for me?
A 135 degree split point self-centers, so the bit starts where you put it without a center punch and without walking across a smooth steel surface. The flatter 135 degree angle also spreads the cutting load and reduces the tendency to grab and snap as it breaks through sheet metal. The HSSC20E has that split point ground on it, which is why it suits drilling overhead in strut and enclosures where punching is awkward.
4) How many drill bits come in a Metallics HSSC20E order?
One bit per order, supplied in a pouch rather than an index or set. If you're stocking a van or a maintenance crib with a standard 3/8 inch size, order the quantity you need as individual pieces rather than expecting an assortment.
5) Is this bit any use for wood or plastic, or is it strictly a metal bit?
It will cut wood and plastic, but a 135 degree split point cobalt bit is ground for metal and leaves a rougher hole in wood than a brad point would. Buy the HSSC20E for the steel work (strut, boxes, panel enclosures, angle) and keep a separate wood set for framing.
6) What's the yellow coating on the Metallics HSSC20E cobalt bit?
The yellow is the characteristic finish Metallics uses on this cobalt line, and it is how you pick the cobalt bits out of a mixed drill index at a glance. The cutting performance comes from the cobalt in the steel itself, not from a surface coating, so a bit that has been resharpened still cuts like new even where the color is ground away.
