Metallics HSD17E – Frequently Asked Questions
1) How long is the Metallics HSD17E twist drill, and will it reach through a deep assembly?
Overall length is 4-5/8 inches. That is a jobber-length bit, so the usable flute depth is a fraction of that once the shank is in the chuck. For drilling through stacked steel deeper than a couple of inches you want an extension-length or aircraft-length bit instead.
2) Is the HSD17E a bright finish or coated bit, and does that matter for drilling steel?
It is a bright finish high-speed steel bit, meaning uncoated HSS. Bright HSS cuts mild steel, aluminum, brass, and plastics fine with cutting oil. If you are drilling stainless or hardened steel repeatedly, a coated bit (black oxide or titanium nitride) holds an edge longer.
3) How many drill bits come in the Metallics HSD17E pack?
One bit per pack, supplied in a pouch. If you are standardizing a crew's van stock on 21/64 for 3/8-16 tapping, order the quantity you need as individual pieces rather than expecting a set.
4) What is the exact part number to order the Metallics 21/64 inch twist drill?
Order Metallics HSD17E. That part number covers the 21/64 inch, 4-5/8 inch overall, bright high-speed steel twist drill sold one per pouch.
