Most helpful customer reviews2 of 3 people found the following review helpful.Core those holesBy Carl AbramsI need to drill five inch round holes in solid cement. For a dry drill, this works quite well. It should be stated somewhere that this bit does require both the shank and centering bit, also, so there's an extra $75 or so. Also, this bit cannot do well in aggregate. Smooth cement and concrete it does quite nicely in, though. When you get to the maximum depth (about 3 inches) then pull the bit out and chisel out the initial cut, then you can finish drilling. I've gotten 20 holes out of it without resharpening yet.See all 1 customer reviews...
