The flush-trimming attachment for the M-Power CRB7 offset router base makes quick, safe work of levelling edge banding. The 5/16" thick Perspex plate mounts to the underside of the base, providing clearance for the bit and allowing the base to act as an outrigger for stability. A bearing runs along the edge of the work to guide the bit. This allows the router to sit flat on the work, rather than balancing on a narrow edge as when using a conventional flush-trimming bit. The attachment can also be used for trimming screw plugs or joinery wedges.
