Metallics BTT15 – Frequently Asked Questions
1) How deep a hole can I drill with the Metallics BTT15 7/8 inch masonry bit?
It is an extra-long bit at 18 inches overall, so after the shank and flute transition you have working length to pass through thick block, brick veneer, or a poured concrete wall in one shot. That is the reason to pick this one over a standard-length 7/8 inch bit, which tops out well short of a full wall section.
2) Is a 7/8 inch masonry bit the right size for running conduit through a block wall?
A 7/8 inch hole is the common pass-through size for 1/2 inch EMT and for setting larger masonry anchors and sleeve anchors. The BTT15 cuts that diameter and its 18 inch length lets you go clean through the block rather than drilling from both sides and trying to meet in the middle.
3) Can I use the BTT15 masonry bit in a hammer drill, or is it for rotary only?
It is a carbide-tipped style masonry bit on a round 1/2 inch shank, which is what a hammer drill in hammer-plus-rotation mode is built to spin. In plain rotary mode it will cut, just slowly, and in hard aggregate you will burn the tip. Keep it clear of dust by backing out periodically on a hole this deep.
4) How many bits come in a Metallics BTT15 order?
One bit per order, supplied in a pouch. If you are drilling a run of 7/8 inch holes through concrete and want a spare on the truck, order quantity accordingly, because there is no multi-bit pack behind this part number.
5) What part number do I order for the Metallics extra-long 7/8 inch masonry bit?
BTT15 is the Metallics part number, and it is the only model on that designation: 7/8 inch diameter, 18 inch extra-long, 1/2 inch shank. Give that number and the diameter when ordering so it is not confused with shorter 7/8 inch bits in the same family.
