Elevate your circle work with pro-grade precision

The Jasper 390 XLC Router Circle Cutter Jig is engineered to transform bold ideas into clean, repeatable circular cuts. With a generous size range that spans from 7 in to 52 3/4 in in 1/4 in increments, you can tackle everything from subtle accents to dramatic round features without changing tools. The result is consistent, shop-tested performance that helps you approach each project with confidence rather than guesswork.

Built to endure real-world use, the jig is milled from hardened, workshop-grade acrylic. Its clear, tough material keeps your lines visible while resisting the wear that comes with frequent setup changes and long working sessions.
