Circle Cutting Jig | How to Cut Perfect Circles With A Router
Looking for precision, accuracy and repeatability?
A router is one of the most effective tools for producing perfectly round circles when paired with a circle cutting jig. By pivoting the router around a fixed centre point, the jig guides the cutter along a precise path, eliminating the inaccuracies that often come with marking and cutting by hand.
Whether you're creating a one-off project or producing multiple identical components, a circle cutting jig delivers consistent, professional results with minimal setup time.
Why you might need one
If your projects regularly involve circular work, a circle cutting jig can quickly become an essential workshop accessory. It's ideal for:
- Creating perfectly round tabletops and circular furniture components
- Making wooden clocks, signs and decorative wall art
- Producing speaker enclosures and audio projects
- Routing circular recesses, inlays and cut-outs
- Cutting repeatable circles for batch production
- Achieving cleaner, more accurate results that require less finishing work
For many woodworkers, it's the fastest and most accurate way to create circles of virtually any size.
How to create perfect circles
Using a circle cutting jig is straightforward:
- Mark the centre point of your workpiece.
- Drill the pilot hole using the supplied precision drill guide.
- Secure the jig's pivot pin into the centre point.
- Attach your router to the jig.
- Set the required radius or diameter using the calibrated scale.
- Make a series of shallow passes, increasing depth gradually until the cut is complete.
- Remove the finished workpiece and lightly sand the edge if required.
The result is a smooth, accurate circle with clean edges and exceptional dimensional accuracy.
