I want to cut an 18" X 18" square out of my concrete driveway to plant a shrub. The driveway butts up against the concrete foundation of the house, and one edge of this square would also butt up against the foundation. I realize I could buy a concrete blade for my skil saw, but that wouldn't get me up close enough to the foundation to do the job. Instead, could I use a concrete bit (carbide?) in an electric drill and drill a series of closely-spaced holes, enabling me to punch out the square with a sledge hammer? What are the ramifications? What size and type of bit would I use? What am I overlooking? TIA
