Purchased this "masonry" bit to drill through concrete. One hole and it was done. We were not sure of the depth of the foundation, which is why we purchased this length, but the slab was only about 5 inches deep. First hole was really great - spot on 5/8ths. Second hole was 1/2 inch. Very disappointed that bosch would make a drill bit specifically for a hammer drill that would not hold up to being used in a hammer drill. Perhaps it was defective.... I don't know. Taking it back to request a refund because, in my opinion, this thing should last for more than one hole regardless.

What I was waiting for I don't know. After frying several lesser drills. I got an SDS Plus Bosch. The bits drill and drill and and show zero wear. Don't waste time and money on the others, you will save in the long run.
