ABSTRACT:
A matched pair of two rotatable cutting tools (bits) is adapted to be individually chucked into a common router. Each of these two cutting tools includes a shaft with a removable nut, two or three cutters, one or two bearings, and suitable shims. A first bit has cutters shaped to remove material from the edge of a planar wooden article such as plywood that requires a finished appearance, to form a preferably rounded concave dado in the plywood edge. A second bit has cutters shaped to form a mating wood insert having a preferably rounded convex shape that matches the contour of the concave dado in the plywood edge. The mating wood insert is glued into the dado in the plywood to complete the finished edging.
