Metallics HSD28E – Frequently Asked Questions
1) What size hole does the Metallics HSD28E drill bit cut, and how deep can it reach?
The HSD28E is a 1/2 inch high-speed twist drill bit with a 6 inch overall length, so it cuts a 1/2 inch hole and gives you reach for drilling through built-up framing, studded walls, or stacked material where a jobber-length bit bottoms out. Ordered as a single bit, not a set.
2) Is the Metallics HSD28E a bright finish bit or black oxide?
Bright finish. The HSD28E is an uncoated bright high-speed steel twist bit, which is the standard general-purpose choice for drilling steel, aluminum, and wood with cutting fluid. If you want the added lubricity and corrosion resistance of a coating for dry drilling in steel, look for a black oxide or titanium-coated bit instead.
3) Can I use the HSD28E to drill holes for electrical conduit or strut mounting?
Yes, within reason. This is a 1/2 inch high-speed steel twist bit sold as electrical supply stock, so it is the right tool for drilling 1/2 inch holes in strut, enclosure sheet steel, panel backs, and mounting brackets. For 1/2 inch knockouts in an existing box, a step bit or knockout punch gives a cleaner hole than a twist bit.
4) How does the Metallics HSD28E come packaged for a service van or MRO crib?
It ships in a pouch as a single bit, which suits replacing one worn 1/2 inch bit in a van stock or MRO crib rather than buying a full index. If you are standardizing a toolroom, order the individual sizes you actually burn through instead of a boxed set.
