Metallics HSD9 – Frequently Asked Questions

1) What size hole does the Metallics HSD9 twist drill make, and how long is the bit?
The HSD9 cuts a 3/16 inch hole and the bit measures 3-1/2 inches overall. That overall length is the whole bit, not the usable flute depth, so for deeper holes in thick stock plan on a longer bit. For hardware mounting and pilot holes in sheet metal and panel work, 3-1/2 inches is plenty of reach.
2) Is the Metallics HSD9 drill bit sold individually or in a pack?
It ships 10 bits to a pouch, under part number HSD9. That is one size only, all 3/16 inch, not an assortment. Electricians burning through bits on panel and strut work order it that way so there is always a spare in the bag.
3) Will a 3/16 inch high-speed steel twist drill work in steel, or do I need cobalt or carbide?
High-speed steel is the right pick for mild steel plate, brackets, strut, and enclosure sheet metal, which is what the HSD9 is built for. It holds a cutting edge and resists heat better than a plain carbon steel bit. What it is not for is masonry, concrete, or block, that needs a carbide-tipped hammer bit, and hardened or stainless steel is where you step up to cobalt.
4) Can I use the HSD9 to drill holes in an electrical panel or junction box?
Yes. Drilling metal panels, enclosures, and boxes for conduit mounting and cable routing is exactly what this 3/16 inch high-speed steel bit is for. Run it slow, keep steady pressure, and clear chips so the flutes do not pack and overheat the edge.
5) Is 3/16 inch the right pilot hole for a 1/4 inch sheet metal screw or a 1/4-20 bolt?
For a through hole, 3/16 inch is undersized for 1/4 inch hardware, a 1/4-20 bolt needs roughly 17/64 inch clearance. Where the 3/16 does its work is pilot holes for screws and bolts in metal framing and structural steel, and tap-size work. If you are bolting through, drill to the fastener's clearance size instead.
6) How do I keep these bits from burning up when drilling steel all day?
Pick the speed for the material, start slow to set the hole so the bit does not wander, then keep steady even pressure rather than leaning on it. Back out to clear chips on deeper holes so the flutes do not bind, and let the bit cool between heavy runs. Burned bits are nearly always too much speed and not enough chip clearing.
