The Roto Hammer Drill is the key to the process. I have drilled many holes in
concrete and you just don't want to use a standard masonary bit and your 3/8"
drill. Rent the best and beefiest roto hammer drill you can find and use a new,
high quality, masonary bit. This combination will punch through the toughest
concrete like butter.
