The Binding cutter has a universal base that will accommodate the Porter Cable, DeWalt and Bosch trim routers. The handle (extrusion) is mounted on the base with two screws and the bearings ride on the side of the guitar keeping the router perpendicular to the surface of the top or back. A knurled knob at the back of the handle allows cutter depth adjustability. The bearings can be positioned any where on the handle to accommodate body widths. A screw at bottom locks the handle in place.
