These bowl bits are designed specifically for routing and shaping the edges of countertops and sinks fabricated from Wilsonart solid surface materials. They produce smooth, accurate edge profiles that match Wilsonart design standards and are recommended by Wilsonart as part of the approved toolset for professional fabrication. Each bit is designed for use with handheld routers equipped with an Ultra-Glide bearing, which guides the cut consistently while protecting the material surface from damage. For any shop working regularly with Wilsonart solid surface, these are the correct tools for the job.
