Rockler Ellipse Router Circle Cutting Jig
The Rockler ellipse circle cutting jig enables precise circles, ellipses, and arcs with mid-size or large plunge routers. It supports ellipse shapes across a broad range of dimensions and proportions. The jig fits most routers with a 6″ base after drilling adjustments. With its sliding dovetail mechanism, the router remains on the cut line, reducing math and guesswork during setup and cutting. Ideal for picture frames, mirrors, signs, and tabletops, this jig speeds production while maintaining accuracy.
Rockler Ellipse Router Circle Cutting Jig (Compact Routers)
Designed for compact routers, this Rockler ellipse and circle jig simplifies cutting with minimal math. It’s especially suited for small signs, frames, and tabletops, handling ellipses from roughly 6″ x 11″ up to 19″ x 24″, and circles from 6″ to 24″ in diameter. Quick setup and straightforward operation make it a practical choice for hobbyists and small-workshop projects where space and weight matter most.
Jasper 290 Router Circle Jig
The Jasper 290 offers 268 circle sizes, from 1½” to 18 3/16″. Constructed from rugged acrylic, it’s built for durability and repeated use. The kit includes calibration tools such as a calibration disc, centering pin, pivot pins, and screws to ensure accurate one-pass cuts with compact routers. The design minimizes trial-and-error, delivering reliable measurements and clean cuts for speakers, decorative pieces, and tabletops.
Sigerio New 4 in 1 Router Milling Groove Bracket
This large-size router jig features an oversized base that fits most handheld routers. Its multi-hole base supports various screw spacings for secure installation, with clear guidance on aligning screw holes for accurate cuts.

GARGENTOL Router Jig Guide Kit
The GARGENTOL kit offers a 29″ maximum radius with a 16″ main scale plus a 19″–30″ extension, enabling large circle cuts. The dual-scale design (inches and millimeters) plus easy scale switching supports quick adaptation for various project sizes. High-precision laser-etched graduations on 6061-T6 aluminum rails provide consistent readings, while the anti-glare finish improves readability in workshop lighting. Perfect for cabinet-making and oversized signage where larger circles are required.
Buying Guide: Key Purchase Considerations
- Cutting range and compatibility: Match the jig’s maximum circle/ellipse size with your typical projects and ensure base/rail compatibility with your router model.
- Accuracy features: Look for calibrated discs, pivot pins, and metal rails with laser-etched scales for repeatable results.
- Ease of use: Jigs with sliding dovetails, quick-release scales, and minimal required math reduce setup time and errors.
- Versatility: Consider whether you need a tool for large circles, ellipses, grooves, or a combination of features (groove guides, extension rails).
- Durability and materials: Hardened acrylic or aluminum rails with sturdy bases withstand repeated use and resist warping in varying temps.
- Ease of installation: Check whether the base fits a wide range of router brands and screw spacings, including common layouts for common handheld routers.
- Project type considerations: For signs, frames, or furniture, assess whether a jig supports both precise circles and ellipses, plus any groove or routing templates you frequently use.
- Price-to-performance balance: More expensive jigs often offer larger ranges and higher accuracy; balance cost with your core needs and typical project sizes.
In practice, the best ellipse jig for router work balances cutting range, ease of use, and durability. For hobbyists focusing on sign making or small frames, compact jigs that eliminate math and simplify setup are highly valuable. For professional shops planning large furniture pieces or oversized projects, larger-radius jigs with extension rails provide essential flexibility and precision. Always pair your jig with a compatible router and ensure proper calibration before starting a project to maximize accuracy and safety.
