Would RecommendI've used cheaper concrete drill bits in the past, but I am actually impressed that I have drilled 14 holes so far and it's still working. I can tell its not quite as easy to drill as the first hole was, but I would guess I will probably get another 6 holes before I look to changing out bits. I think that is pretty good for a concrete bit. I am using a Ryobi hammer drill - I wouldnt try drilling concrete without a hammer drill.

Works, but it's still difficult
Would RecommendCut through the rebar with some effort. Was not "like butter". Right when I thought I should quit trying, I would start again and eventually get through.

Great sturdy bit
Would RecommendMade quick work of the holes I had to to drill in my concrete foundation. Minimal heat gain and a little dip in a cup of water took care of it. Great sturdy drill bit for an sds plus hammer drill
