The Binding cutter has a universal base that will accommodate the Porter Cable, DeWalt,
Bosch and Makita trim routers. The handle is mounted on the base with four 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 of 1/32" per turn. Two binding cutters are available,
standard and adjustable. Standard has fixed bearing where as the adjustable allows
the bearing to move from 1.5 to 2.5 inches.
