Roman ogee router bits cut a distinctive edge profile characterized by a concave curve flowing into a convex curve, creating an elegant S-shaped transition that has been used decoratively in architecture and woodworking for centuries. In solid surface applications, the undermount variant is specifically designed for shaping the edges around undermount sink and bowl openings, providing a refined, classical finish to the countertop edge. These bits are suitable for use on solid surface materials including Corian and Avonite, and add a polished, professional appearance to countertop installations.
