Metallics BFR20 – Frequently Asked Questions
1) Is this a hammer drill bit or a rotary drill bit, and can I use it in a regular drill?
The BFR20 is a carbide-tipped, slow-spiral masonry bit on a plain 3/8 inch round shank, not an SDS shank. It runs in a standard corded or cordless drill chuck, and in hammer-drill mode on a rotary hammer-capable drill with a keyed chuck. If your tool is SDS-Plus or SDS-Max only, this bit will not mount in it.
2) What size anchor does a 1/2 inch masonry bit like the Metallics BFR20 drill for?
The BFR20 cuts a 1/2 inch diameter hole, which is the hole size called for by 1/2 inch wedge anchors, sleeve anchors and drop-in anchors used in concrete and block. Carbide tip and slow spiral flute, so it is intended for masonry, not steel or wood.
3) Can I use this bit to drill through tile, glass or steel studs?
No. A carbide-tipped slow spiral masonry bit is made for concrete, block, brick and mortar. Tile and glass need a spear-point or diamond bit, and steel needs an HSS or cobalt twist bit. Using the BFR20 on metal will round the carbide tip.
4) Why choose a slow spiral masonry bit instead of a fast spiral one?
Slow spiral means a lower flute twist rate, which gives a stronger web behind the carbide tip and clears coarse dust from concrete and brick without the flute packing. Fast spiral geometry pulls material faster and suits softer materials; for hard masonry the slow spiral on the BFR20 is the one that survives the hole.
5) How many bits come in a Metallics BFR20 order?
One bit, supplied in a pouch. It is sold as a single piece rather than a multi-size set, so if you are stocking a truck for several anchor sizes you will be ordering each diameter separately.
6) What part number do I give to order this Metallics masonry bit?
Order it as Metallics BFR20. That is the manufacturer part number for the 1/2 inch diameter carbide slow-spiral masonry bit with the 3/8 inch shank, and there is a single configuration, so there is no finish or length option to specify.
