I used this on a concrete patio. It is long lasting about a hundred holes and I did not have to sharpen it. Durable and inexphensive for masonry nuts this size

One the best masonary bits I've used. Used with a Bosch hammer drill it drills into concrete floors so easily.

Rated 4.0 out of 5.0 by DIYer Got the job done...barely
I was able to get through about 16 holes in 1922 concrete with one of these bits before it was just too chewed up. I got another bit to finish up another 12 holes in ~1950 concrete. This was more difficult and I couldn't drill a few holes as deep as I wanted.
A pro would insist that an SDS hammer drill and corresponding drill bit would be the only way to go. As a DIYer with a cheap hammer drill, this was worth the try over spending $$$ buying or renting and SDS drill. This bit was pretty cheap and lasted as long enough for me to be happy with its value.
