Router Circle Cutting Jig & Edge Guide - Essential Power Tool Accessory for Precision Routing - Router Tool Kit Must-Have

Included is a sheet that shows how to connect to many specific router baseplates, including the square baseplate typical of many palm routers. It's a nice tool, because you attach it to the included bar and that becomes your radius by pinning the other end of the bar in the center of your circle.It took me a moment to figure out how it works, because the baseplate attachment is also a circle, but you're not using that radius, I don't think it matters that the baseplate attachment is a circle, or maybe it matches some routers that have a circular baseplate.

Jig is Made of a aluminum alloy which is sturdy and light. Comes with multiple adaption combinations. Fit my Router with no issues. Great jig for cutting grooves in a circle or edge trimming. Comes with everything shown. Markings are easy to read and set. Great addition to my toolbox and workshop. Recommend.
