Metallics HSD21 – Frequently Asked Questions
1) What size hole does the Metallics HSD21 twist drill bit make?
The HSD21 is a 25/64 inch diameter high-speed steel twist drill, so it cuts a nominal 25/64 inch hole. Overall length is 5-1/8 inches, which gives more reach than a standard jobber bit of this diameter for drilling through studs, channel, or boxed-in framing where a short bit bottoms out.
2) How many drill bits come in a pack of Metallics HSD21?
Five bits per pack, supplied in a pouch rather than loose or in an index case. That is a working quantity for a crew or a service van where bits get dulled or snapped off in steel and you want spares on hand rather than reordering a single bit at a time.
3) Is a 25/64 high-speed twist drill the right bit for drilling steel, or do I need cobalt?
High-speed steel is the general-purpose choice and handles mild steel strut, enclosures, and sheet metal as well as wood when run at a sensible speed with cutting oil. Step up to cobalt or carbide only for stainless, hardened steel, or abrasive masonry, which HSS is not intended for. The HSD21 is an HSS bit at 25/64 inch.
4) What is the exact part number to order the Metallics 25/64 inch twist drill?
Order it as Metallics HSD21. That single part number covers the 25/64 inch by 5-1/8 inch high-speed twist drill in the 5-piece pouch, so there is no size or length suffix to specify.
