Metallics HSD12 – Frequently Asked Questions

1) How many bits come in the Metallics HSD12 1/4 inch twist drill pack?
Ten bits, packed in a pouch. Every bit in the pack is the same size, 1/4 inch diameter by 4 inches overall, so it's a quantity pack of one size rather than an index set. If you need a range of diameters, this isn't the pack for that.
2) Will a 1/4 inch high speed steel bit drill through steel and aluminum, or do I need cobalt?
The Metallics HSD12 is high speed steel, and it's rated for steel, aluminum, wood and plastic. For mild steel and aluminum on electrical and HVAC work it does the job at low RPM with cutting fluid. Hardened steel or stainless is where HSS gives up and you'd want cobalt or carbide instead.
3) Can I use this bit to drill concrete or masonry for anchors?
No. The HSD12 is a high speed steel twist drill for steel, aluminum, wood and plastic. Concrete, block and brick need a carbide-tipped masonry bit run in hammer mode, and an HSS bit will dull immediately in masonry. Use this one for metal enclosures, strut, brackets and pilot holes in wood.
4) What model number do I order for the Metallics 1/4 x 4 inch twist drill?
Order model HSD12. That's the Metallics part number for the 1/4 inch diameter by 4 inch high speed twist drill in the 10-piece pouch.
5) Is the 4 inch length the cutting depth, or overall?
The 4 inches is the drill's length as stated, not usable hole depth. On a jobber-style twist drill the chuck takes up the shank and the flutes only run part of the body, so plan on noticeably less than 4 inches of hole. For deep holes clear chips often, which the 4 inch body makes easier than a stub bit.
6) Is 1/4 inch the right size to drill out for a 1/4-20 bolt or a strut mounting hole?
For a 1/4-20 bolt or screw to pass through freely, 1/4 inch is a tight nominal fit, so most trades step up slightly for clearance. Where this 1/4 inch bit earns its keep on electrical work is mounting holes for boxes, conduit supports and bracket hardware sized to 1/4 inch, plus pilot holes for larger lags and anchors.
7) Why buy a 10-pack of one size instead of single bits for a maintenance crew?
A 1/4 inch bit is the size that goes dull or snaps fastest on MRO and electrical work, so a pouch of ten of the same size keeps a truck or shop crib stocked without reordering each time one breaks. The pouch also keeps the cutting edges protected between jobs.
