SET OF 3 ZERO CLEARANCE INSERTS CUSTOM MADE FOR SKIL 10 IN. TABLE SAW (SPT-99). THE INSERTS COME PRECUT WITH A RIVING KNIFE SLOT. THESE ARE IDEAL FOR PRECISE CUTTING AT 90 DEGREE CUTS ONLY. CUT ECO-FRIENDLY MEDIUM DENSITY MDF, PAINTED SIDE BLUE. .****DO NOT BUY FOR THE TS-6307-00 MODEL***. THAT MODEL HAS A DIFFERENT TYPE OF PLATE ALSO FOR SALE IN OUR SHOP. SET SCREWS ARE INCLUDED TO ASSIST WITH LEVELING THE PLATE. ZERO CLEARANCE INSERTS ARE CALIBRATED TO A SPECIFIC SAW, A SPECIFIC BLADE, AND A SPECIFIC BEVEL ANGLE. THEY CAN ONLY BE USED ON CUTS WHERE THOSE PARAMETERS ARE MET. FOR EXAMPLE, ONCE AN INSERT IS MADE FOR A STRAIGHT-ON 90° CUT, IT CAN’T BE USED ON OTHER CUTS. IF YOU NEED TO MAKE A 45° BEVEL CUT, YOU CAN’T USE YOUR 90° CUT INSERT. YOU MUST HAVE A 45° INSERT, OR SWAP IN THE ORIGINAL THROAT INSERT. EACH ZERO CLEARANCE INSERT IS GOOD FOR ONLY ONE SPECIFIC BEVEL ANGLE. MADE IN THE US.
