This video shows you how easy it is to cut and make holes in cement backer board. The first thing you want to have is safety glasses to protect your eyes. To make a punch out hole you have to draw an outline of the hole with a pencil or pen. Use a drill to make several holes inside your outline. A jigsaw will cut out your punch hole. Push the punch hole out. Make a straight cut by marking the front of the board with a pen and a straight edge and use the scoring knife along the straight edge to cut the board. Stand the board up and support it and make a cut with the scoring knife on the other side of the board at the cut.
