Freud's Reversible Wainscoting Bit is a fast, easy way to add rail & stile profiled wainscoting to existing wall surfaces. The bit height is set one time for male and female joints without requiring fence or height adjustments. Just route stiles face down and rails face up for a perfect fit. Works with stock from 1?2" to 5?8" thick, and mills matching frame joints with remarkable ease and precision. Use with hand-held or table-mounted routers to cut hardwood, softwood, plywood or composites.
