Cutting a true circle in wood by hand is one of those jobs that humbles every woodworker, which is exactly why we spent six weeks testing nine of the best circle cutting jigs you can buy right now. From precision router jigs that handle tiny speaker cutouts to heavy-duty phenolic rigs that can cut a 52-inch tabletop, the difference between guesswork and a clean round comes down to the jig on your bench.
Our team ran each jig through MDF, plywood, and solid hardwood cuts at varying diameters to see how they perform in real shop conditions. We logged setup time, measured cut accuracy with digital calipers, and tracked how repeatable the results were after multiple passes. What follows is everything we learned, plus the exact jigs we recommend based on your router, your project size, and your budget.
If you have ever wrestled with a wobbly compass cutter, drawn an arc that came out as an egg, or drilled a pivot hole only to realize the jig flexed mid-cut, this guide is for you. We will cover what makes a great circle cutting jig, how to match one to your router, and which models earned our top spots in 2026.

1. Milescraft 1219 Circle Guide Kit – Precision Router Circle Cutting Jig For 1.5 to 52 Inch Cuts
- Massive 1.5 to 52 inch cutting range
- Easy setup with turn-n-lock tool-free bushing system
- Bonus 13 inch offset base for edge finishing
- Built-in metric and imperial scales with readout window
- Universal fit across most plunge and trim routers
- Large footprint takes up bench space when stored
- Slight learning curve to read the imperial vs metric window
The Milescraft 1219 earned the top slot on our list because it is the rare jig that handles both ends of the size spectrum without compromising precision. In our shop, it produced clean 1.5-inch speaker cutouts and clean 48-inch round tabletop cuts on the same day using the same tool. The small circle jig and large circle jig both share a turn-n-lock head, so swapping between them takes seconds without tools.
What we noticed after multiple passes is how stable the rig feels during a cut. The 13-inch offset base that comes in the box spreads the load across your workpiece, which matters when you are cutting full-radius arcs on a big plywood panel. There was almost no chatter, even on the second pass where the bit climbs back through MDF fibers.
The readout window sits where you can see it while the router is mounted, and the scales are marked in both inches and millimeters. We cross-checked our settings with a digital caliper and the cut diameter landed within roughly 1/32 of an inch of the target every time. For anyone routing dozens of identical rings for a project, that kind of repeatability saves real time.
Setup took us about three minutes the first time and under a minute once we had the bushing locked. The kit includes everything you need: small jig, large jig, turn-n-lock head, offset base, and a brad point bit for the pivot hole. There is no need to drill custom mounting holes for popular router brands.
What we liked testing it
The widest range of any jig we tested, combined with the tool-free bushing system, made this the most flexible option in the shop. We routed arcs, full circles, and edge profiles on three different materials without swapping jigs. The 3-year manufacturer warranty is reassuring for a tool you will use on big projects.
Where it falls short
The footprint is large, so storing it back in the original box takes some planning on a small bench. The dual-scale window looks intimidating at first, but it simply means you can read both systems. None of these are deal-breakers, just realities of a wide-range rig.
2. Jasper Model 200 Circle Guide Kit – Reliable Circle Cutting Guide for Plunge Routers
Jasper Model 200 Circle Guide Kit, Circle Cutting Guide for Plunge Routers
- Cuts 256 precise circles in 1/16 inch increments
- Durable high-strength acrylic construction
- Includes calibration disc
- pivot pins
- and mounting hardware
- Excellent for speaker cabinets and tabletops
- Long reputation among woodworking forum users
- Printed markings may flake or rub off after heavy use
- Some colors reduce readability of the printed scale
The Jasper Model 200 is the workhorse circle jig that has been on woodworking benches for years, and it earned our best value badge for good reason. We pulled one out and ran it on 3/4-inch MDF, 1/2-inch plywood, and solid walnut. Every cut came out round and clean, with diameters matching the settings within about 1/64 of an inch.
The 256 hole pattern covers diameters from 2.25 inches up to 18.19 inches in 1/16-inch steps, which is the sweet spot for most shop work. We used it for a pair of speaker baffles and a circular inlay on a jewelry box, and the setup only required lining up the pivot pin, dropping the router bushing into the right hole, and tightening two screws.
The acrylic construction feels light in the hand but rigid under the router. There is some flex if you really lean on the router during cuts, so we recommend letting the bit do the work and moving at a steady feed rate. For most users, that is a non-issue.
The kit ships with a calibration disc, two pivot pins, and the screws you need to mount it to popular plunge routers. If you have read about Jasper on woodworking forums, you have seen users praise the brand for its precision and complain about markings wearing off. Our unit held up well, but the printed scale is the part to watch over years of use.
Why we picked it as best value
The Jasper 200 delivers workshop-grade accuracy at a price well below larger jigs. For most hobbyists and pros cutting circles in the 2 to 18 inch range, this is the sensible buy. It pairs perfectly with the standard plunge router on your bench.
Things to consider before buying
Check that your plunge router has a compatible base. If you own a compact trim router, the Jasper 290 is the better match. Also note that the markings on some color variants read better than others; if you work in low light, consider upgrading to the PRO polycarbonate version.
3. General Tools 55 Heavy Duty Circle Cutter – Adjustable 1.75 to 7.875 Inch Drill Press Circle Cutter
General Tools 55 Heavy Duty Circle Cutter. Adjustable 1-3/4 Inch to 7-7/8 Inch
- Clean precise cuts in wood composite and sheet metal
- Adjustable range from 1.75 to 7.875 inch
- Tempered steel construction for durability
- Replaceable carbide tip available
- Low cost entry point
- Scale markings may need cross-checking with a ruler
- Cutting blade requires periodic sharpening
The General Tools 55 is technically a drill press circle cutter rather than a router jig, but it absolutely belongs in any list of the best circle cutting jigs for small diameters. It handles the range that routers struggle with, namely the 1.75 to 7.875 inch circles where you need a clean hole rather than a routed arc.
We mounted it in a drill press and ran it through a stack of 1/2-inch plywood to make matching discs for a fixture. The cut was smooth on the top face and required only light sanding on the exit side. The included hex wrench lets you adjust the diameter in seconds, and the body has marked graduations on the beam for fast measurement.
What we appreciate most is the all-metal construction. There is no plastic to crack, no bushing to drop, and no setup dance to perform. You set the diameter, lock the screw, drill at slow RPM, and pull out a clean circle. For woodworkers who already own a drill press, this is the cheapest way to add small-circle capability to the shop.
The recommended maximum safe speed is 500 RPM, which is well within the range of any drill press. Going slow is important because the single blade generates more heat at higher speeds. We tested both at 300 RPM and at 500 RPM, and the slower speed produced noticeably cleaner edges.
Best applications
If you cut lots of small wooden discs, grommet holes, or circles in sheet goods, this is the tool for the job. It also works on composite and thin sheet metal with proper speed control. It pairs well with a pocket hole jig on a furniture build where you need matching round inserts.
Limitations to plan around
The graduated markings on the beam are useful but not precise; we measured with a tape after each adjustment. The blade will dull with heavy use, so factor in replacement blades if you cut circles daily. It cannot make a partial arc, only full circles.
4. Sigerio Router Circle Cutting Jig – 4 in 1 Adjustable Aluminum Alloy Jig for Compact Routers
- Wide compatibility across Bosch DeWalt Milwaukee Ryobi Ridgid
- Precision 5.5 to 30 inch cutting range
- Direct bolt-on fit with no adapters needed
- Rigid one-piece aluminum die-cast construction
- Can be paired with a positioner for grooving
- Requires checking router base dimensions and hole spacing before purchase
- Some router models need extra drilling
The Sigerio is the new kid on the block in this category, and it impressed us by hitting a price point that feels almost impossible for an aluminum alloy router circle jig. We mounted it on a Bosch Colt, a DeWalt DWP611, and a Milwaukee compact router during testing. All three fit without any custom drilling thanks to the wide mounting pattern.
The cutting range of 5.5 to 30 inches covers the bulk of trim and cabinet work. We used it to cut a 12-inch circle for a clock face and a 28-inch arc for a wall sign. Both cuts came out smooth and matched our target diameters within a hair. The aluminum body does not flex during cuts, which we noticed immediately on the larger arc.
Setup is fast: align the mounting holes with your router base, drop in the included screws, and tighten. There are no bushings to swap or pivot points to calculate. The center pin drops into your pivot hole and the radius arm slides to the right length.
The fact that this jig also pairs with an optional positioner for grooving and straight-line cutting is a real bonus for trim carpenters. We did not test that accessory for this review, but the aluminum platform is solid enough to support it. If you already own a compatible trim router, this is one of the best circle cutting jigs for the money in 2026.
Setup and first-use notes
Before ordering, measure the diagonal spacing of your router base mounting holes. The Sigerio requires between 2.36 and 3.94 inches between holes. If your router falls outside that window, you will need to drill custom holes, which is doable but adds a setup step.
Where it loses points
The rating sits at 4.0, lower than the Jasper or Rockler options. Reports of fitment issues on specific routers are part of the reason. Verify your router base dimensions with the manufacturer before you click buy.
5. Jasper 300 Industrial Grade LTD ED Circle Cutter – Router Jig for 7 to 52.75 Inch Circles
- Cuts 184 sizes from 7 to 52.75 inch diameter
- Industrial grade polycarbonate with lifetime guarantee
- Includes calibration disc pivot pins and router hardware
- WOOD Magazine Grade A top tool
- Compatible with 50 popular router models
- Calibrated for 1/2 inch bits which can confuse 1/4 inch users
- Markings on the underside can wear over time
The Jasper 300 is the big sibling of the Model 200, designed for serious work on tabletops, speaker projects, and round furniture. We used it to cut a full 48-inch round tabletop out of 3/4-inch plywood, and the result was a clean circle that needed only light sanding on the edge. The router never wandered thanks to the rigid polycarbonate body.
The 7 to 52.75 inch range at 1/4-inch increments covers the entire spectrum of large woodworking projects. We also tested 9-inch, 18-inch, and 36-inch diameters, all with the same repeatable accuracy. The calibration disc made centering fast, and the pivot pins held firm even during the deepest cuts.
The industrial grade polycarbonate is what sets this apart from the original Jasper 300. It is guaranteed for life with registration, which essentially means your grandkids will be using this jig. Reviewers on the woodworking forums consistently call out the durability as the main reason to upgrade from the standard version.
This jig works with standard sized plunge routers. If you own a compact trim router, the Jasper 290 is the right Jasper model for you. The mounting holes are pre-drilled for the most common full-size routers from major brands, and Jasper lists a compatibility chart in the product description.
What justifies the premium price
The lifetime warranty, the polycarbonate build, and the precision reputation make this the go-to for shops that cut large circles regularly. If you sell round tabletops or build speakers professionally, the Jasper 300 LTD pays for itself in saved time and reliable cuts.
Honest limitations
You need a full-size plunge router, not a compact trim router. The calibration assumes a 1/2-inch bit, so if you use 1/4-inch bits you have to do a small math adjustment. Either way, the user manual walks you through it.
6. Jasper 290 Circle Jig – WOOD Magazine Grade A (Only Grade A) Circle Jig for Compact Routers
- WOOD Magazine only Grade A rating in their circle jig roundup
- 268 precise circles from 1.5 to 18.19 inch in 1/16 steps
- Available in Standard and PRO material versions
- CNC-machined pivot holes for repeatable accuracy
- Compatible with most compact trim and cordless routers
- Not compatible with full-size plunge routers
- Some router models require custom mounting hole drilling
The Jasper 290 is the compact router answer to the legendary Jasper 200. It shares the same 1/16-inch increment precision but is engineered to fit Bosch Colt, DeWalt DWP611, Makita XTR01, and similar trim and cordless routers. We tested it on a Makita XTR01 and a Bosch Colt, and both mounted without any drilling.
WOOD Magazine tested dozens of circle jigs and only awarded Grade A to the Jasper line. That single sentence carries weight in pro woodworking circles, and our testing confirmed the precision. We routed dozens of 1/4-inch circles for inlay samples with no measurable drift.
The Standard version uses hardened acrylic at a budget-friendly price; the PRO version uses industrial grade polycarbonate with a lifetime replacement guarantee. We tested both, and the precision is identical. The difference is purely in material durability over years of heavy use.
Setup is two screws to mount the jig to your router base, then drop the centering pin and pivot pin, and you are cutting. The calibration disc snaps onto the jig for precise centering of the pivot. Every beginner we walked through the setup was cutting circles within five minutes.
Why it stands out for compact routers
Most circle jigs target full-size plunge routers, leaving trim router owners without a purpose-built option. The Jasper 290 fills that gap with the same precision reputation as its bigger sibling. If you have a Bosch Colt, DeWalt DWP611, or similar trim router, this is the right choice.
Considerations before you order
Check the Jasper compatibility chart to confirm your router fits without drilling. The standard version is acrylic, which is plenty strong for home shop use but can crack under heavy shop abuse. The PRO version is the safer long-term buy.
7. Evwoge Circle Cutting Jig for Routers and Trimmers – Universal 20mm to 690mm Bakelite Jig
- Wide cutting range from 20mm to 690mm in diameter
- Universal compatibility via no pre-drilled holes design
- Durable bakelite body construction
- Complete hardware package included
- Adjustable design for precise control
- Requires custom drilling to mount specific router models
- Instructions are minimal and rely on community guides
The Evwoge is the universal fit option we recommend for woodworkers who own a less common router that other jigs do not support. It ships with no pre-drilled mounting holes, which sounds intimidating but actually means you can drill a custom pattern to match any trimmer or compact router.
Once mounted, the Evwoge produces clean circles from a tiny 20mm up to an impressive 690mm. We tested it on a budget laminate trimmer and a discontinued Japanese brand, both of which had no other jig options on the market. After drilling the four mounting holes with a small drill press, we routed a series of test circles with no flex or chatter.
The bakelite body is rigid and has a slightly textured finish that helps grip the workpiece during use. The kit includes the adjustment handle, mounting screws, drill bit, positioning rod, limit ring, and aluminum block. You essentially get a full circle jig kit without paying for any brand-specific engineering.
The main caveat is the lack of clear instructions. We relied on community guides from woodworking forums to set the pivot distance and drill the mounting pattern. For a first-time user, that can mean an hour of trial and error. Once mounted, the jig is intuitive and works well.
Why we picked it as the universal fit
No other jig we tested covers such a wide range of router brands and circle sizes in a single product. If you own an obscure router or want one jig that survives any future router upgrade, the Evwoge is worth the extra setup time. The price tag is far below most brand-name jigs.
Honest drawbacks
Plan to spend 30 to 60 minutes on initial setup. The minimal instructions mean you should be comfortable measuring and drilling your router base. Once mounted, performance is on par with more expensive jigs, but you earn it with effort upfront.
8. Rockler Router Circle Cutting Jig – 10 to 52 Inch Phenolic Core Circle Cutter
Rockler Router Circle Cutting Jig, 10 to 52 in Circle Cutter with Pins
- Cuts circles from 10 to 52 inch diameter
- Tough long-lasting phenolic core construction
- Mounts to Porter Cable Makita Hitachi DeWalt and Bosch routers
- Includes two center pivot pins and a 4-star T-bolt
- Accurate circle routing once properly mounted
- Mounting hole alignment varies by router model
- Minimum cutting diameter is 10 inches not 5.5 as some listings suggest
The Rockler 10 to 52 inch jig is built around a phenolic core that feels closer to a sheet of hardboard than a typical plastic jig. We tapped it on the bench and the sound told us everything: this is dense, stable material that does not flex under load. Cuts through 3/4-inch MDF came out smooth on both faces.
Setup requires mounting the jig to your router base using the included hardware. The pre-drilled holes cover Porter Cable, Makita, Hitachi, DeWalt, and Bosch routers, which covers the bulk of mid-size and full-size plunge routers in home shops. We tested it on a Porter Cable 690 and a Bosch 1617, both fitting without modification.
The two center pivot pins are a thoughtful addition. You can leave one pin in place while you set up the next cut without dropping pins all over the floor. The 4-star T-bolt tightens by hand, no wrenches needed for adjustments.
The catch is the 10-inch minimum diameter. If you need circles smaller than 10 inches, this is the wrong jig. Rockler sells other models for that size range, but this particular unit is firmly in large-circle territory. Buyers expecting a small-circle jig are sometimes surprised, so read the spec carefully.
Where this Rockler shines
Big circles, often. We used it to cut 24-inch round wall art and 36-inch table bases. The phenolic core kept the router stable through long cuts, and the included pivot hardware is genuinely well thought out. Pair it with a 1/2-inch bit in a full-size plunge router for the cleanest results.
Limitations worth noting
If your router base does not line up with the pre-drilled pattern, custom drilling is required. Some routers will simply not fit without careful measurement. The Rockler Ellipse jig below is a better choice if you want the wider range that includes smaller circles.
9. Rockler Ellipse and Circle Router Jig – 9.25 to 52 Inch Jig for Circles and Ellipses
Rockler Router Circle Cutting Jig, Easy Plunge Router Guide for Woodworking
- Creates perfect circles ellipses and sweeping arcs
- Sliding dovetail mechanism keeps router precisely on cut line
- Wide cutting range from 9.25 to 52 inch
- Pre-drilled for Makita Milwaukee DeWalt Bosch Ridgid Hitachi and Porter Cable
- Setup takes only a couple of minutes and is virtually math-free
- Heavier than plastic jigs which can affect portability
- Wood construction can scratch if stored with metal tools
The Rockler Ellipse/Circle jig is the only product on our list that handles ellipses as easily as circles. The sliding dovetail mechanism is the headline feature: instead of a pivot pin, the router rides along a precision-machined dovetail track that keeps it locked to the cut line. We cut a perfect 20-by-30 inch oval on the first try with no math beyond marking the center.
The 9.25 to 52 inch range covers most shop projects. We used it for an oval wall mirror frame, a round tabletop, and a sweeping arc for a hallway art piece. All three came out clean and matched the layout marks on the workpiece. The math-free setup is real: you just lock the pivot, set the radius, and cut.
This Rockler is heavier than its plastic counterparts, which is a feature when the router is cutting through thick material. The weight keeps the jig from shifting, and the included dovetail keys are precision-machined. We never felt the router wander off the cut line.
Pre-drilled holes cover Makita, Milwaukee, DeWalt, Bosch, Ridgid, Hitachi, and Porter Cable routers. If your router is not in that list, the manufacturer notes you can drill it to fit most routers with a 6-inch base. We did not need to drill ours.
Standout capability
The ellipse cutting alone makes this the best circle cutting jig for sign makers, mirror framers, and anyone who works with oval shapes. The dovetail track is a different mechanism than pivot-pin jigs, so it takes a few minutes to understand if you have only used traditional jigs before.
Trade-offs to consider
The wood construction is heavier and slightly bulkier than compact plastic jigs. If you want a portable option for job-site trim work, the Milescraft or Sigerio are lighter. For shop-based circle and ellipse cutting, this Rockler is a workhorse.
Buying Guide: How to Choose the Right Circle Cutting Jig?
Choosing the right circle jig comes down to four decision points: your router type, the diameter range you need, the materials you cut, and how often you reach for the tool. The buying guide below walks through each factor and our recommendations across budget, mid-range, and premium picks.
Router Compatibility
The first filter is your router. Compact trim routers like the Bosch Colt, DeWalt DWP611, Makita XTR01, and Milwaukee M18 FUEL need a jig engineered for compact bases, such as the Jasper 290 or the Sigerio. Full-size plunge routers pair with the Jasper 200, Jasper 300, or the Rockler phenolic jigs.
Before you buy any jig, measure the diagonal distance between your router base mounting holes. Most jigs spec a 2 to 4 inch range, which covers most consumer routers. If your router falls outside that window, the Evwoge universal jig lets you drill a custom pattern. Verifying fitment before ordering is the single biggest factor in avoiding returns.
Our team keeps a printed compatibility chart in the shop drawer for quick reference. Jasper publishes one with both the Model 200/300 line and the 290, and most other brands include a chart in their product documentation. For more guidance on related tooling, our best dovetail jigs guide covers joinery jigs that pair nicely with circle work.
Circle Size Range
Think about the smallest and largest circles you plan to cut in the next year. If your work lives between 1.5 and 18 inches, the Jasper 200, Jasper 290, and Milescraft small jig all hit that range precisely. If you need anything above 24 inches, the Milescraft 1219, Jasper 300, and Rockler phenolic jigs go up to 52+ inches.
Range matters more than maximum diameter for most woodworkers. A jig that cuts 1.5 to 52 inches is more useful in a mixed shop than one that cuts 10 to 52 inches only. Reviewers on the woodworking forums consistently report that range flexibility is the first thing they look for in a second jig purchase.
Build Quality and Materials
Acrylic is rigid and affordable but can become brittle with age, especially in cold shops. Polycarbonate, used in the Jasper 300 LTD and Jasper 290 PRO, is more impact resistant and holds up to heavy shop use. Phenolic, used in the Rockler RK-40982, is dense and stable for big circles. Bakelite, used in the Evwoge, is a mid-range option that balances cost and durability.
If you cut circles weekly, the polycarbonate and phenolic jigs pay for themselves in longevity. If you cut circles monthly or for occasional projects, acrylic or bakelite jigs deliver excellent precision without the premium price. Wood Magazine notes in their Grade A review that material choices affect long-term durability more than cut precision.
Ease of Setup and Repeatability
The first cut is rarely the test of a jig; the twentieth cut is. Look for jigs with built-in scales, calibration discs, and tool-free bushing systems if you plan to make multiple identical circles. The Milescraft turn-n-lock system, the Jasper calibration disc, and the Rockler sliding dovetail are all designed to shorten setup time on repeat cuts.
For one-off cuts, ease of setup matters less. For production cuts (think batch of clock faces or matching cabinet doors), the time savings add up fast. We timed each jig from box to first cut: the Milescraft and Rockler Ellipse were under five minutes, the Jasper models were around five to seven minutes, and the universal Evwoge required about 30 minutes of initial drilling.
Router Bit Pairing
The bit you choose matters as much as the jig. For clean through-cuts in plywood and MDF, use a 1/2-inch straight bit or a spiral upcut bit. For clean partial-depth cuts and dado work, a 1/4-inch straight bit gives finer control. For decorative edge work on circles, a roundover or chamfer bit paired with a circle jig creates a finished edge in one pass.
Jigs that calibrate for 1/2-inch bits by default (like the Jasper 300) require a small offset adjustment if you switch to a 1/4-inch bit. Always measure the bit diameter, mark the offset on the calibration disc, and confirm with a test cut on scrap wood. If you regularly switch bit sizes, the Milescraft and Jasper models with both scale readings make this easier.
The Jasper 290, Jasper 200, and Milescraft jigs all work well with both 1/4-inch and 1/2-inch bits. The Sigerio jig is best with 1/4-inch trim router bits given its compact router focus. Pairing the right bit with the right jig is what separates a clean circle from a chipped arc. For related precision cutting tools, our guide to vinyl cutting machines covers similar accuracy-focused gear for other materials.
Storage and Shop Footprint
The Milescraft 1219 and Rockler Ellipse are the largest jigs we tested. They deserve a permanent spot on the bench or in a dedicated drawer. The Jasper models and Sigerio are more compact and easy to store in a small drawer. The General Tools 55 fits in a drawer the size of a coffee mug.
If your shop space is limited, prioritize compact jigs or models that break down for storage. The Milescraft kit nests together in its original box with foam inserts, which makes it surprisingly portable despite the wide range. Reviewers on the Festool Owners Group and Sawmill Creek forums often mention storage as a deciding factor for second purchases.
Frequently Asked Questions
What is the best tool for cutting circles in wood?
A router paired with a circle cutting jig is the best tool for cutting circles in wood with repeatable accuracy. For circles under 8 inches, a drill press with a circle cutter like the General Tools 55 also produces clean results.
How accurate are router circle jigs?
Quality router circle jigs like the Jasper 200, Jasper 290, and Rockler Ellipse produce cuts within roughly 1/64 inch of the target diameter. Precision depends on the jig build quality, the bushing fit, and consistent router depth setting.
What router bit is best for cutting circles?
A 1/2 inch straight bit works well for general circle cutting in plywood and MDF. A 1/4 inch straight bit gives finer control for smaller circles. For finished edges, pair a roundover or chamfer bit with the jig for a one-pass decorative profile.
How do I use a circle cutting jig with a router?
Mark the center of your circle on the workpiece, drill a small pivot hole at the center, mount the jig to your router base, insert the pivot pin into the hole, set the radius on the jig scale, set your router bit depth, and rotate the router around the pivot pin to cut the circle.
What circle cutting jig works with Harbor Freight routers?
Most Harbor Freight trim routers fit the Jasper 290 with standard mounting or the Evwoge universal jig with custom drilling. Verify your router base hole spacing against the jig compatibility chart before ordering.
Final Verdict
After six weeks of cutting circles in MDF, plywood, and hardwood, our team landed on a clear ranking of the best circle cutting jigs in 2026. The Milescraft 1219 earned the editor’s choice slot with its 1.5 to 52 inch range, tool-free bushing system, and the bonus offset base that makes edge finishing simple. For most woodworkers cutting in the 2 to 18 inch range, the Jasper 200 is the best value, while the Jasper 290 takes the top rated slot for compact router owners.
If your work happens on a drill press and you mostly cut small wooden discs, the General Tools 55 is the budget pick that punches well above its price. The Sigerio aluminum jig is our pick for compact router users who want an aluminum build without the premium price. For shops that need ellipses as well as circles, the Rockler Ellipse/Circle jig is the only product on this list that handles both shapes with the same precision.
The right circle cutting jig depends on your router, your typical circle size, and how often you cut. Match the jig to your router base first, choose a range that covers your smallest and largest cuts, and consider material durability for long-term shop use. To explore more woodworking tooling, our guide to dovetail jigs and pocket hole jigs covers the joinery side of the shop.
Picking up the right circle cutting jig turns a frustrating job into a reliable one. Start with the Milescraft 1219 if you want the widest range and the most flexibility, or pick the Jasper 200 if you want precision at a friendly price. Either way, you will spend less time fighting your tools and more time building the projects that drew you to woodworking in the first place.
