These two flute cutters offer a method of mitre jointing timber or man made boards accurately. Unlike V-groovers these can be relied on to create a joint at 90 degrees.
This cutter can be used against the fence on your router table or guided by the optional bearing kit TB1985.
NB: This is a large cutter. Please ensure it is suitable for your machine. It should only be used in a fixed machine and at 10,000 rpm maximum.
