The M.Power CRB7 router base, compatible with most routers, adds functionality to the tool. The wide footplate helps with tilt support and easier offset routing. Using the base, a router can cut circles with diameters from 3/4 inch to 8 3/4 inches. Two small legs can be attached to the bottom to improve accuracy while mortising; they also add stability when cutting thin materials. In addition, the base can be set up to create repetitive dadoes, like on a faux panel. Also comes with an anti-tilt leg.
