The Bosch TS1017 is a zero-clearance insert for the Bosch GTS15-10 10 In. Worksite Table Saw. This insert allows users to create the zero clearance, supporting the workpiece closer to blade. It offers improved control that minimizes tear out that can happen with a standard insert. It also helps reduce wood damage by making precision cuts at 90 degrees, reducing the kerf clearance to the thickness of the blade.
