I assume a hammer drill is the tool of choice for this task?


Correct. The difference between a "regular" drill and hammer drill is like
night and day when it comes to drilling masonry. Good luck!

Don't forget a SHARP bit. I put a laundry tub in the
garage a while back. I went through all my bits before
I finally found one that would actually drill 4 holes
in the floor. Before I do any more concrete drilling
I definitely need some new bits.
