Product description: 

This ingenious, easy-to-use table saw blade accessory allows users to create the same cut from different blades every time, without moving, measuring or recalibrating the rip fence scale. Set it up once for each blade and the cut line remains the same, regardless of which blade is used for the cut.

Six stainless Arbor Shims included:

Stack and adjust from 0.003" to 0.045" in 1/1000 increments

When changing blades, users place the shims against the arbor, putting the blade on second, and know that the zero cut line will remain the same.
