The metal jig clamps to the bar and calibrated adjustments set the filing and tilt angles for cutters, as well as the height for depth gauge jointing.
A pawl mechanism ensures that all teeth are identically filed. A well-designed and manufactured jig, it will accept 6" and 8" round files (not included) up to 1/4" diameter.
Files (top-quality Grobet Swiss®) are available separately. Check your saw manual for file size before ordering.
