Metallics NHSD29 – Frequently Asked Questions

1) What size hole does a #29 drill bit make?
A #29 bit is a wire-gauge size measuring 0.136 inch in diameter, which is the standard tap drill for an 8-32 machine screw thread. That is why electricians keep them on the truck: 8-32 is the thread used on most device screws, ground screws, and enclosure hardware. The Metallics NHSD29 set gives you ten of that one size rather than a mixed index.
2) Is the Metallics #29 drill bit set ten different sizes or ten of the same bit?
Ten of the same bit. All ten in the NHSD29 pack are #29 hi-speed steel twist drills, so it is a consumable refill pack for a size you burn through, not a graduated index. If you need a range of diameters you want a separate drill set.
3) Can I use these #29 bits to drill steel enclosures and strut, or are they wood bits?
These are hi-speed steel twist drills rated by the manufacturer for metal, wood, and plastic, so steel panels, enclosures, and brackets are in range. For metal work use a cutting fluid and let the bit clear chips on deeper holes, which is what keeps the cutting edge from burning. They are not masonry bits.
4) What do electricians actually use a #29 twist drill for?
Mounting work, mostly. Metallics lists panel and enclosure mounting, conduit and raceway installation, and fabricating component brackets, plus general construction and MRO drilling. The practical use case is drilling for 8-32 screws, since #29 at 0.136 inch is the tap drill for that thread.
5) Do I need a tap to go with these #29 bits, or do they thread the hole themselves?
A twist drill only bores the hole. If you are threading the hole for an 8-32 screw you need an 8-32 tap as a separate item; #29 is the drill size that precedes it. If you are drilling clearance holes instead so the screw passes straight through, #29 is too tight for an 8-32 shank and you want a larger clearance bit.
6) Does the Metallics NHSD29 pack come in a case or holder?
The ten bits ship as a bulk pack. Metallics recommends keeping them in a protective case or bit holder between uses to protect the cutting edges, so if you want them indexed on the truck plan on supplying your own holder.
