quote: "do you think it'd drill the 1/2" bit with reasonable ease?"
I think the answer to that depends on the aggregate that was put into the concrete. I used a Milwaukee AC 1/2" hammer drill with a 1/2" bit to drill through 8" of concrete and almost came to t stop when I hit aggregate that must have been something like quartzite. I have hit quartzite with a cold chisel that ended up with a dull chisel and nary a mark on the rock so I know how hard it can be. I love my Porter-Cable cordless but have no desire to try drilling concrete with a cordless on a job like yours. I would spend too much time changing battery packs and running out of juice just as I was getting there.
