For 1/2″ or 3/4″ thick solid surface.
This bit only removes 1/2″ of material greatly reducing the drag of the cut, the amount of dust being produced, and speeds up the process immensely. The Delrin Bearing sleeves a 1/2″ steel bearing. Because the effort needed to remove the sink cutout due to the single flute cut, the bearing rolls on the side of the sink effortlessly reducing the pressure and friction that sometimes causes the bearing to fall apart. This bit leaves a 1/8″ overhang.
Replacement bearing is #PE-831-1150-BGR.
