New Craftsman/Rigid Phenolic Zero Clearance Insert for Table Saws
Leecraft phenolic table saw inserts reduce splintering and chip-out on the bottom side of regular or dado table saw cuts. The opening in the insert is cut on the table saw to the exact width of the saw blade’s kerf. The matching kerf prevents thin slices of wood from jamming in between the blade and the throat plate during a cut. It also reduces the amount of tear-out that can happen with a standard insert.
