Rated 5.0 out of 5.0 by Good Bit Used this bit do drill holes in concrete for anchord. It drilled the last hole as well as the first. Eight holes total. Good price too. I will be buying more of these bits in different sizes. February 3, 2014
Rated 5.0 out of 5.0 by Delighted with result Was a bit nervous about using this drill bit. had just laid 12x12 slate tile and needed to secure toilet flange to the floor by drilling through the tiles. Had nightmares previously of drilling through the tile and cracks appearing, with all associated nightmares. With this drill bit, going through the tile was a breeze at slow speed, regular rechargeable drill with no hammer action was so so easy October 19, 2012
