Using the hole cutter, drill the center hole of the circle you want to cut. Adjust the diameter gauge to the correct diameter and insert into the center hole. Once inserted, drill through the material and then drill in a clockwise motion.

Drill in a clockwise motion with a slight angle toward the direction of the cut. Do not use excessive force, let the cutting bit do the work. Using excessive force will cause the drill bit to break.
