Hinge boring jigs only drill the cup hinge on the back of the doors. This jig locates where to attach the hinge to the cabinet. The left side is for face frame over-lay hinges, the right side is for frameless (Euro) over-lay and inset hinges. Mark a pencil line where the center of the hinge plate will be on the cabinet, place the steel pins against the front edge of the cabinet, slide the center line on the jig over the pencil line. Use an Vix style bit (7/64") to drill for the screws .Not for drilling 35mm hinge cup holes in the back of the door.
