Router Bits from Woodline | we specialize in router bits and shaper cutters that are premium quality and a great value.

One bit cuts both the tongue and the groove. Cut the tongue first by aligning the cutter on the desired height of the joint. Once the tongue is cut, raise or lower the cutter to align one of the solt cutters with the tongue. Cut the corresponding groove in the exact location needed for a precision joint without complicated measurements. For thicker materials, flip the board over to create a dual tongue and groove that will hold up to an incredible amount of stress.
