The most innovative bit for the construction of doors and drawers. Two cutters are embodied in a unique bit to allow you to cut two perfectly joining profiles efficiently and effectively, and also to reduce costs by investing in a single CMT bit rather than multiple cutters. For use in stock from 18mm (11/16”) to 22,2mm (7/8”).


Safety precautions: always unplug the router before making any adjustments to the bit. Use push blocks and featherboards to control the workpiece.
