In the Spring I need to remove about an 8"x8" chunk of concrete from the edge of a garage foundation for drainage. Can a "hammer drill" be used to core out some adjacent holes to facilitate knocking this out? How does one work? Does it drill? Or hammer? ..or does it do both at once? If it does both at once, is it hammering while the drill bit is still in place? Or do you alternate a drill bit with some kind of chisel bit? Advise and thanks.
