Metallics HSD7 – Frequently Asked Questions

1) What size are the Metallics HSD7 twist drill bits, and how many come in the pack?
The Metallics HSD7 is a 10-piece set of 5/32 inch diameter high-speed steel twist drill bits, each 3-1/8 inches in overall length. They arrive in a pouch, so the whole set stays together in a tool bag. One model, MPN HSD7.
2) Can these high-speed steel bits drill steel, or are they only for wood?
High-speed steel handles metal. The HSD7 bits are specified for metal fabrication and structural steel work along with general construction, and HSS holds a cutting edge under the heat of drilling steel better than plain carbon steel. For hardened steel or masonry you need a different bit (cobalt or carbide tipped).
3) Are all ten bits in the Metallics HSD7 set the same size, or is it an assorted index?
All ten are identical 5/32 inch bits, not an assorted set. That is the point of it: a contractor drilling a repeated 5/32 hole all day gets nine spares in the pouch instead of one bit and a stalled crew. If you need a range of diameters, buy an assorted index instead.
4) Will a 5/32 inch bit drill the pilot hole for a 3/16 inch sheet metal screw or anchor?
5/32 is the common pilot size for 3/16 inch fasteners in steel and sheet metal, and that is the diameter these Metallics HSD7 bits cut. The set is aimed at electrical work: panel and junction box mounting, conduit support brackets, and structural steel. Check the fastener maker's pilot chart for your specific anchor, since anchors vary more than screws.
5) Will the 3-1/8 inch bits reach through a deep electrical box or panel enclosure?
Overall length is 3-1/8 inches, which includes the shank held in the chuck, so usable drilling depth is shorter than that figure. It is sized for standard electrical boxes, panels and structural material with working clearance. For anything deeper than a few inches of stacked material, step up to an extended-length or aircraft-length bit.
6) Do these bits fit a standard cordless drill chuck?
Yes. These are round-shank twist drills at 5/32 inch, well under the 3/8 inch capacity of a typical cordless drill or driver chuck, so they seat in any keyless or keyed chuck. They are not impact-rated hex shank bits, so use a drill rather than an impact driver.
7) Is the twist flute design going to clear chips when drilling into sheet steel?
The helical flutes on these bits pull chips up and out of the hole, which keeps the bit from binding and grabbing in thin steel and gives a cleaner hole. Back the bit out periodically on deeper holes and use cutting oil in steel to keep the edge from burning.
