Setting your tool at the precise necessary height is crucial, whether you are working with a table saw, router table or shaper. Precision Router Table Setup Bars feature an exclusive three-gauge design that makes them ideal for many applications. Each setup bar has a concave step at the bottom that straddles your router bit or saw blade, allowing more exact height adjustments. On the top edge of each bar is a step that acts as a gauge to test the depth of your cuts once complete. There is another step on the end of the setup bars that can be used to set the distance between a tablesaw blade and the fence or between a router bit and the fence.<br>Specifications:<br>Sizes: 1/8", 3/16", 1/4", 5/16", 3/8", 7/16", 1/2"
