Sigerio Router Circle Cutting Jig for DeWalt/Bosch/Milwaukee Compact Routers – 4 in 1 Adjustable Router Jig, Aluminum Alloy Circle Cutting Guide for Trim Routers, 5.5–30" for Circles, Arcs & Grooves

As a 67-year-old DIYer who has spent years with a handsaw and a prayer, I finally decided to modernize my workshop with the 4 in 1 Router Milling Groove Bracket. Using a circle jig for the first time felt daunting, but this tool paired with my Bauer 1/4" collet palm router turned out to be a game-changer for my latest cabinet project. 1. The Experience: First-Time Success I’ll admit, I was skeptical about how "multifunctional" a bracket could really be. However, the setup was intuitive even for a novice. I mounted my Bauer palm router—which fit perfectly onto the base—and was cutting clean, circular speaker holes within 15 minutes. The movement is remarkably smooth; I didn't experience the "chatter" or jumping I feared when transitioning from straight lines to arcs. 2. Precision & Build Quality The thickened aluminum alloy construction feels industrial-grade. It has a weight to it that screams "professional," which helps dampen the vibrations of the corded motor. The "Rose Red" Finish: It’s not just for show—the vibrant color makes the laser-etched imperial and metric scales incredibly easy to read under shop lights. Hole Cutting: The accuracy is spot on. I was able to dial in a 10-inch radius, and the resulting cut was a perfect circle with zero wander, something I could never achieve with a jigsaw. 3. Gap-Filling Details: Bauer Compatibility While the manual is a bit brief, here is what you need to know for a palm router setup: The Base: The detachable base plate has a versatile hole pattern. If you're using the Bauer 6.5 Amp model, the alignment is steady, though I recommend using a bit of Loctite on the mounting screws if you’re doing high-volume cuts to prevent vibration loosening. Range: It handles a radius from roughly 3 to 15 inches easily, which covers almost any home cabinetry need. 4. Balanced Objectivity Pros: Stable Control: The secondary handle provides excellent leverage, keeping the router flat against the workpiece. Versatility: It’s a 4-in-1 tool, so I’ve already used it as a straight-edge guide for dados as well. Cons: Pivot Pin: The center pivot pin is a bit small. I found that pre-drilling a tiny pilot hole for the pin makes for a much more secure "swing." 5. Who is it for? This is perfect for the retiree woodworker who wants professional-looking results without the steep learning curve of a CNC machine. It makes the Bauer palm router feel like a much more expensive plunge setup. In other words, it is a big impact item for DIY enthusiasts and it's functionality is spot on.

This 4-in-1 router milling groove bracket is an excellent woodworking tool! The aluminum alloy construction feels strong and durable, while the rose red finish gives it a unique, stylish look. It’s easy to set up and adjust, and I love how smoothly it guides the router for accurate cuts. The adjustable design makes it extremely versatile — cutting circles from 10” to 58” is effortless and precise. I’ve used it for several projects already, and the results are clean and professional-looking. It’s a huge time saver compared to trying to measure and cut freehand. What really stands out is the stability it provides. Once set, it holds steady, which gives me confidence in every pass. For anyone serious about woodworking or looking to expand their tool collection, this router guide is a fantastic investment.

This jig is GAME changer for my router! I was looking for a perfect milling groove bracket so that I could use my router to cut out circles and this is the one I landed on. It is very accurate, and made of great quality. The best part is it is super compact so it packs up so nicely. In a world of having so many tools - I need tools that pack up with ease. This is great quality jig, and a great value for your money.

Seems well made, high quality materials. Assembly instructions could be more clear. However, this bracket does not fit Bosch Colt 1.25hp palm router. There was no way to align the minimum two holes between the router and bracket plate.

Excellent router bracket. Super easy to use, fits router perfectly, comes with all parts needed and instructions, excellent accuracy and functionality. Very happy with this product.

I want to give this 5 stars and I think it could be worthy. I bought this for my Metabo (Hitachi) router. Its not listed as fitting but it does fit. The issue is that the blade of the jig that comes from the circle lines up directly under one of the handles. That stinks but not a deal breaker. Still works. Setup is quick though. Pull plastic plate off router, line up jig, attach, and go! The next issue is probably the bigger issue. There is no pivot pin of any sort. Not sure if other manufacturers come with a pin but this does not. It does come with some nails that you have to nail into your project but now you have holes in you project. The nails are are also smaller than the hole you need to pivot. Like way smaller! So there is some slop when making the cuts. Id say about a 1/16" to an 1/8" if not paying attention. So get the exact size nail to fit hole if you can... Mines also did not come with a smaller knob like in the picture. I steady came with large butterfly knobs. That goes back to the comment of the blade lining up under the handle. Have to put the piece together prior to attaching handle. Perhaps that's how its supposed to be(?). But I think it's finely crafted. Sturdy solid construction. Way cheaper than the plastic ones at Lowe's & HD. Just use caution when setting up. But seriously, no pivot pin?

Standard size might fit a lilliputian router. It certainly doesn't fit the ubiquitous Bosch Colt. the plate is too small and the holes don't align. I considered for a short second drilling holes to fit the Bosch since it is Aluminum and then came to me senses. Why should I? In fairness there is a warning about the SMALL size but the picture they have is of the Bosh Colt - so go figure. it's going back - very disappointing it seems well made so unless you have a miniature or some brand that fits the specified dimension - Avoid!

Fit my (small) router perfectly. Easy to use. Allows for accurate cuts. Functions as intended. Great value.

Muy buena herramienta para cortar círculos para efectos de buen material de aluminio le quedó perfecto y bien aliniado con los orificios de la base a mi rauter crasfman y lo mejor vas carsto que uteas marcas

Sehr gute Qualität bin sehr zufrieden.

Ho comprato questo strumento per fare tagli rotondi nel legno, è tutto in alluminio, semplice ma ben fatto. Secondo me è uno strumento utile. Come segnalato da un altro utente, bisogna fare attenzione alla compatibilità con la propria minifresa. Io ho una Ehinell a batteria e i fori delle viti non erano in posizione compatibile. Ho risolto il problema sostituendo il supporto fresa originale con uno di altra marca. Metto la foto del tipo che ho preso che è facilmente riconoscibile e venduto anche qui su Amazon sotto diversi venditori e marchi.

Doesn’t work with a Ryobi router….. as advertised
