Make your own beautiful hardwood floors that will last a lifetime. Our V-Tongue & Groove bits give a tight fit between boards, and leave a decorative V-groove between boards. Unlike most square profile tongue and groove router bits, our matched V-Tongue & Groove set produces an elegant 45° "V" groove in stock from 5/8" to 7/8" thick. This type of joint is ideal for custom flooring, wainscot paneling, cabinet backs, and even Shaker-style cabinet doors. Both router bits feature bearing guides that will make setting-up and running quick and easy. Features a 1/4" thick tongue and groove joint.
