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

Really awesome attachment to have if you're into woodworking. One of the hardest shapes to freehand when cutting wood is a circle or perfectly curved corners/ sides. So this attachment is a must have if you are going to attempt any cuts like that because it makes it super easy and really precise. The set up is simple and as long as you lock everything in correctly, you really can't go wrong with it at all. The sizing of the tool is great so it allows for you to cut a variety of different size circle cuts giving you great flexibility for your different needs. The material of the product also feels pretty solid so it'll give you precise cuts since it isn't shaky and doesn't move much when you lock it into place. If you're looking for a super versatile tool that will help you get perfect circle cuts, then this is the tool to get.

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.

I have some square at home, but it is not accurate enough for me to install the cabinets door handles and hinges. This is the perfect solution for me that doesn't cost more than $50. It fits well with my router and easy to use. The quality doesn't feel cheap like some plastic tool out there. I was able to install my 4 cabinet doors without issue. Pretty stable for a product at this price range.

I use a small router jig for strait cuts all the time, so when I saw this 17" jig from Sigerio I was very interested and bought one. Unfortunately, it’s just awful. To start, it doesn’t fit my DeWalt router even though the description reads: “This router jig is designed for DeWalt compact routers. No adapters or drilling needed.” The only way I could mount it was by switching the thumb screw and using three washers to add enough height, which is ridiculous. After all that it barely works. The base is too small and if the guide rail is set past 6 inches there isn’t enough support. Even if you grip it as tightly as possible it’s difficult to control and moves around leaving uneven cuts. Overall, I think this product is poorly designed and will be returning it.

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?

Really nice easy to use, and priced nicely. I just used today to cot a circle and how easy it was to do it. I did not want to pay the higher price ones of triple the cost. Sturdy construction is another vslue

This router circle cutting jig is sturdy and well made for DIY woodworking projects. The adjustable design makes cutting accurate circles, arcs, and grooves much easier. I really like the 5.5" to 30" cutting range for different project sizes. The aluminum construction feels durable and keeps the jig stable during use. Setup is fairly simple once you match the mounting holes to your router. It works especially well for signs, round tabletops, and decorative woodworking. Overall, a very useful jig for the price and a great addition to a router toolkit.

The circle-cutting feature is defective and not fit for its advertised purpose. The supplied pivot nail fits loosely in the slider and allows several millimeters of movement unless hammered fully flush, which then makes it difficult to remove. This creates an unstable pivot, inaccurate circles, and an unnecessarily awkward setup. The product functions as an edge guide but not usable for a circle-cutting jig.

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
