It will work although not my favorite.You could also use a sawzall blade wich is thicker than a hacksaw blade and cut 2-3 slices across the face.You could also use one of those 1/8th inch cut off wheels with a mandrel,there like 3 inches round maybe and put it in a drill.I bought one from harbour freight to use to cut off nails,pipe,ect in hard to reach places.If ya use a variable speed drill you can go slow and easy.The object is just to get some kind of an indentation so the wood or plastic squeses into the perforation a little.
