This unique V-Tongue and Groove set from Sommerfeld's produces beautiful tongue and groove paneling or flooring with an attractive 45° V-pattern. The difference between this set and other sets is that both our bits have bearings to help guide the workpiece accurately. Our bits are carefully matched, so it's easy to change bits to make the male and female cuts. For fast production on large stock, set up two router tables with one dedicated to each cutting operation.
