Metallics BFRS145 – Frequently Asked Questions
1) What size hole does the Metallics BFRS145 masonry bit drill, and what drill will it fit?
The BFRS145 is a 5/16 inch diameter carbide-tipped masonry bit with a 1/4 inch round shank, so it chucks into any standard rotary drill or driver that takes a 1/4 inch shank. The 5/16 inch cutting diameter is the hole size for a 1/4 inch sleeve anchor or a 1/4 inch Tapcon-style screw in concrete or block.
2) Can I use the BFRS145 carbide bit in a hammer drill or an SDS rotary hammer?
It has a plain 1/4 inch round shank, so it runs in a standard three-jaw chuck, including a hammer drill set to hammer mode. It will not go into an SDS-Plus or SDS-Max rotary hammer, which needs a splined SDS shank, not a round one. For SDS tools you need an SDS-shank masonry bit instead.
3) How many masonry bits come in a pack of Metallics BFRS145?
Five bits per pack, supplied in a pouch. That makes it a sensible buy for an electrical crew running repeated 5/16 inch holes for strut, clamp, or box anchors in concrete, where bits dull or snap on a long run.
4) Will the Metallics BFRS145 drill through steel or wood, or is it masonry only?
It's a carbide-tipped masonry bit, built for concrete, block, brick, and mortar. The brazed carbide tip is ground for percussive drilling in stone, not for cutting metal or wood, so use a twist bit in steel and a brad point or auger in wood. Pushing a masonry bit through steel studs or plate will round the tip over fast.
5) What does the fast spiral flute on this masonry bit actually do for me?
The BFRS145 uses a fast spiral (high helix) flute, which clears dust out of the hole more aggressively than a standard-flute masonry bit. On deeper holes in concrete that matters, because packed dust is what stalls the bit and overheats the carbide. It also helps when you're drilling overhead for conduit hangers and the spoil has to climb out against gravity.
6) What is the Metallics part number for the 5/16 inch masonry bit so I can reorder it?
Order it as Metallics BFRS145. That number covers the 5/16 inch diameter, 1/4 inch shank fast spiral carbide masonry bit in the five-piece pouch.
