Rated 4 out of 5 by 1reviewer.
Rated 4 out of 5 by This is a core bit designed for hammer drills with an SDS-Max chuck. It is intended for dry cutting concrete and concrete block, and worked quite well, cutting clean holes in a filled concrete block wall in our control room. Unlike some core bits (diamond tipped models, for instance), this is intended to be used in a rotary hammer mode -- fortunate, since our particular Dewalt drill can't shut off hammer mode and just rotate.The useful length of the bit is 17 inches (the overall length is 22 inches, part of which winds up in the chuck), more than enough to get through even a thick wall. On the down side, the depth of the cutter portion itself is only 3"; you will have to drill a couple inches, break out the core piece with a hammer and chisel, and repeat the process until you get all the way through the material. It's tedious, but the relatively shallow depth probably helps prevent having the bit bind in the hole.The pilot drill bit unscrews easily, and I imagine it is available as a replacement part.All in all, this bit works quite well, despite the somewhat inconvenient stop-and-go process.
