If you're thinking about buying this accessory, you already know what you'll be using it for. I bought this to fit handles in the sides of a cutting board. While you can make a jig to run on a regular router, I've used it on my CNC and it cuts through hard maple really well. I have used CMT cutters in the past (both molding and routing) and have never been disappointed with the quality. However, the price is another matter. But at CMT you definitely get what you pay for.
