The Bosch TS0801 is a dado insert for the Bosch GTS18V-08 PROFACTOR 18V 8-1/4 In. Table Saw. This insert is designed for dado-cutting blades. It replaces the throat plate when stacked dado blades are used on a table saw. Inserts with a solid surface allow the user to custom cut the width, which reduces splintering. This insert is made of steel construction. The max blade size is 6 In. cutting, and the cutting width is 1/2 In.
