Works for concrete.

Drilled a 2 1/4” hole through 9” of concrete, not block and stumbled upon 5/8” rebar. I used 2 drills because they were getting hot. I put the drill in hammer mode, it seemed to cut better. High speed worked best. Took 2 good batteries and about 20 minutes. Bad ass bit. You can do it.

Pros

Easy to use

Cons

The diamond core may become dull over time with frequent use
