Bridge City’s two new HP-6v2 Dado Kits attach to the HP6v2 plane and let you make straight cut for dadoes or grooves by using the guide fence or running the plane body against a board clamped to your stock. The cutting depth for each Dado kit is a minimum of two times the width of the iron when the scoring cutter is attached, and up to eight times the iron width without the cutter. They sell for $159.
