Totally unsatisfactory for 5/8 plywood. It could work on a wall plate. Immediately, wood began to burn, and when the teeth really began to cut, the vibration was deadly. I was hoping to use a 6 inch hole saw to cut the plywood for the large bottled wine rack but couldn't cut any holes. Do yourself a favor and don't go here if you want to carve anything other than maybe cardboard or paneling.
