Rated 5.0 out of 5.0 by HBeyea Wow! This drill bit rocks.
I had to drill 16 anchor bolt holes into very hard aggregate concrete. My regular 1/2" drill was making no headway. I purchased this drill bit and a rotary hammer and all the holes were done in less than 5 minutes. This bit really works well.

Drilled holes in concrete without a problem. Did not drill enough to evaluate how long it would last but saw no degradation while using it. Positive lockup in the Bosch drill.

I used this drill with my new 18V Rotary Hammer drill to drill holes for rebar fence posts around my asparagus patch. The desert rabbits gobble anything green. I drilled into decorative wall blocks. I went 3 inches deep in under 4 seconds each hole and this drill showed no signs of use at all. They are less costly if you buy a set.

I bought this to secure my shed to a concrete pad. The bit was sharp and cut with moderate effort on my part.
