Shop Tips

For the best results when creating decorative grooves or cove-style edges, multiple passes are recommended. Begin with a shallow initial cut and gradually increase the cutting depth with each pass. This technique helps reduce strain on the router and bit while producing a cleaner finish and helping minimize splintering or tear-out.
