The 15° Drawer Drilling Jig (DDJ) will increase the speed and quality when attaching 5 piece shaker drawer fronts. The DDJ allows you to drill a pilot hole at PRECISELY a 15° angle through the corner of the drawer. The screw is now perfectly positioned in the center of the stile for maximum holding power. You no longer need washers or oversized screw heads to get the drawer front attached or adjusted. This allows the built-in adjustability of under mount slides to easily fine-tune the drawer front to the cabinet.>.
