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.

Began to get dull after only drilling only 6-8 holes in the concrete. Totally useless after 15 holes. When I have to drill holes every two feet for the bottom plate in my basement, this was pretty much a waste of money.

I bought this to replace a regular masonry bit that had dulled. I had to drill anchor holes in an old driveway slab, and this drill went through it with no problem using a regular drill motor. Masonry drills are made for cinder block, brick and stucco. This Bluegranite is made for hard concrete, and the cost is not much more.
