Hammer drills are just the best thing going for drilling concrete. I
wondered if he'd hit rebar.

I've heard that power nailers (the ones with the .22 blank shells)
will do nails into concrete. Never tried it, but this I've heard.


And they WILL do a U-Turn and come back at you if you hit aggregate or
rebar. I know. I've seen it many times.

You can't beat a roto-hammer. Even a small one like a Milwaukee. They use
a different manner to hammer and turn the bit than a hammer drill. As a
hammer drill is better than a regular drill, so is a roto-hammer better than
a hammer drill.

If you need to do any serious or repetitive drilling of holes, either buy or
rent a roto-hammer. And you don't need the jackhammer size unless you are
core drilling. There are roto-hammers made that are the same size as the
Makita and comparable hammer drills. (the larger ones)
