These cutters sets are designed to make V-groove paneling with a strong tongue and groove joint. Each set can be used with 1/2", 3/4", and 1" stock. Shims are included to allow the thickness of the tongue to increase as stock increases. UP190 cuts a V-groove on both sides of the paneling, while UP191 only cuts a V-groove on one side.
