Step 3
Put on safety goggles, gloves and a respirator mask, and put in earplugs. Drill a hole at each corner of the opening outline with a 5/8-inch masonry bit. Repeat the process on the other side of the wall. Step 4
Choose which side you will start with, and punch a hole in the other side with a sledgehammer, which will help draw concrete dust away from you as you cut through the wall. Step 5
Insert the masonry saw blade in one of the holes, and cut along the line. Cut through the remaining lines until you have created the opening. Move to the other side and cut along the lines. Warning
You may need to brace the opening with an angle iron before framing a door or window.
