Metallics BFRB21 – Frequently Asked Questions
1) What size hole does the Metallics BFRB21 masonry drill bit make, and how deep can it go?
The BFRB21 is a 1/2 inch diameter carbide-tipped masonry bit with a 4 inch length. The 1/2 inch cutting diameter is the hole size, and the 4 inch overall length limits how deep you can set an anchor, so for through-drilling thicker concrete or block walls you need a longer bit.
2) Is the Metallics BFRB21 sold individually or in a pack?
It ships 25 bits to a pouch, so the BFRB21 is a bulk buy rather than a single bit. That suits an electrical contractor or MRO crew drilling 1/2 inch anchor holes day after day; if you only need one or two bits, this is more than you want.
3) Can I use the Metallics BFRB21 carbide bit to drill concrete and brick for anchors?
Yes. It is a carbide-tipped masonry bit, which is the tip type used for concrete, brick, and block. At 1/2 inch diameter it matches the hole size for 1/2 inch mechanical anchors and sleeve anchors. Carbide masonry bits are not meant for steel or hardened metal.
4) What kind of jobs is the Metallics BFRB21 1/2 inch masonry bit stocked for?
It is part of Metallics' electrical supplies line, the same range as their anchors and fasteners, so it is bought for drilling masonry anchor holes when mounting strut, conduit straps, boxes, and panel backing to concrete or block walls. The 25-piece pouch is a consumable stocking item for an electrical van or storeroom.
