A Guide to Roundover and Ovolo Router Cutters

A Guide to Round-Over and Ovolo Router Cutters

These are one of the most useful edge moulding cutters, as you can produce both profiles with the same cutter. These are generally used to soften the appearance of square-edged worktops, window boards and furniture. By lowering the cutter a top step can be routed. By performing a second pass on the reverse of the workpiece, a full bull-nose can be achieved. The round over is self-explanatory, whilst the ovolo has two small shoulders at the extremes of the radius. To use the same cutter for both profiles, you have to vary both the depth of cut and the size of the bottom bearing, or you can combine the two and have a round over with just a single shoulder.
