Adjustable Slotting Router Bits offer the flexibility of adjusting the kerf to the desired width, from 1/8″ to 1/4″ or 1/4″ to 1/2″ without the use of shims. By releasing the counter nut, one can set the kerf using a precise dial. By rotating the dial, you are able to change the kerf in 0.01″ increments. This system saves a lot of time needed to adjust and readjust a conventional slotting router bit to the right kerf
