Metallics BFRS165 – Frequently Asked Questions
1) What size hole does the Metallics BFRS165 masonry bit drill, and what shank does it need?
The BFRS165 is a 3/8 inch diameter carbide-tipped masonry bit with a 1/4 inch shank. The 1/4 inch round shank chucks into any standard 3/8 inch or larger keyed or keyless drill chuck, so you do not need a rotary hammer with an SDS collet to run it. Drill a 3/8 inch hole with it for 3/8 inch sleeve anchors, wedge anchors, or lag shields in concrete, block, or brick.
2) Will the BFRS165 masonry bit work in a regular hammer drill or does it need a rotary hammer?
It runs in a standard corded or cordless hammer drill. The 1/4 inch straight shank clamps in a three-jaw chuck, so it is not an SDS-Plus or SDS-Max bit and will not fit those tools. If you are drilling 3/8 inch holes in poured concrete all day, an SDS rotary hammer with an SDS bit is the better tool; for block, brick, and occasional concrete anchoring this is the bit you want.
3) How many bits come in a pack of Metallics BFRS165?
Five bits per pack, supplied in a pouch. That is a contractor pack rather than a single bit, which is how electricians and MRO crews usually buy 3/8 inch masonry bits since carbide tips dull fast drilling block and aggregate.
4) Is the BFRS165 the right bit for setting 3/8 inch concrete anchors for conduit strap and strut?
Yes. A 3/8 inch carbide masonry bit is what you use for 3/8 inch sleeve and wedge anchors and for 1/4 inch tapcon-style screws in oversize prep, which is the usual way strut channel, unistrut trapeze, and conduit straps get anchored to concrete walls and decks. Metallics files it on the electrical side of its fastener line for exactly that work.
5) Can I use the Metallics BFRS165 to drill tile, steel, or wood?
No. It is a carbide-tipped masonry bit, ground for concrete, block, brick, and mortar. Running it in steel will chip the carbide, and it will tear rather than cut wood. Glazed tile and porcelain need a diamond or spear-point tile bit instead.
6) What does fast spiral mean on a masonry drill bit?
Fast spiral describes the flute geometry, a steeper helix than a standard masonry bit. It clears dust out of the hole faster, which keeps the carbide tip cooler and cuts bind-up when you are drilling deep 3/8 inch holes overhead or into block. The BFRS165 uses that fast spiral flute with a brazed carbide tip.
7) How do I order the Metallics 3/8 inch fast spiral masonry bit?
Order by part number BFRS165. There is one configuration, the 3/8 inch diameter with 1/4 inch shank, sold five to a pouch, so there are no finish, length, or shank options to specify.
