Freud's Beadboard Tongue and Groove System mills perfect beadboard in a variety of thicknesses from 3/8" to 3/4", and in almost any width. Mill beadboard from any hardwood or softwood, and use it to create a beautiful effect as wainscoting, wall or ceiling paneling, cabinet and bookcase backs, and more. The tongue and groove bits includes two slot cutters: use the 1/4" cutter to mill a 1/4" thick tongue and groove for 1/2" to 3/4" stock, or switch to the 1/16" cutter for thinner material. Once the tongue and groove joints are complete, use the solid carbide Radius V-Groove Bit (#20-301) to complete the beadboard design.
