Needed to cut some circles for a project. Was very pleased of the accuracy.I already owned a circle cutter from one of the large woodworking companies, but it is so long that I had to clear off my entire workbench surface to cut a hole - big or small. I needed to cut a perfect 6" hole - within 1/16" inch accuracy. The small hole cutting jig worked perfectly. Easy to set up and easy to replicate results. Very good value for the price.I watched the set up video and was using it within 20 minutesMilescraft makes a lot of very good router accessories, and this is probably their best one. It has two circle cutting attachments, depending on the diameter you are trying to cut. As well, it includes an extra offset router base which can be very handy in some situation. It is a quality piece of equipment in all respects!simple to use and very accurate.Works great but the second smaller attachment doesn’t have the guides. Kinda worthless. The kit from lowes comes with guides.Worked well once setup. The plastic base screws did not fit my Bosch router so I reused the screws from the Bosch base with washers, otherwise the heads would be too small. The centering pin wobbles and is not straight but it’s good enough for setting up the template. I used a 1/2” bit instead of the provided 1/4” bit and had to compensate on the measurement bar. Just cut biased to the side of material you don’t need then sneak up on the final size of the tolerance requirement is tight. The drill bit for the center bushing screw on the part wobbled but has a nice sharp point like a spade but to avoid walking when starting the hole. I used low speed on my drill because of the wobble and it worked fine. That bit was actually nicer than a standard S or split point drill bit.Excelente productoNo accuracy ruin two projectsThe Circle Guide Kit worked exactly as advertised. Perfect circles with only a small amount of setup and little effort to cut.I was in the market for a plunge router (requires plunge router) so I actually bought the guide first, then bought a plunge router based on their comparability sheet. I bought the DW618PK for use with this but the guide covers a large number of routers including some of the lower-end plunge routers. With a quality router the fit was perfect and the cuts were exact.This cut also comes with a bit too so don’t worry about having to find a 1/4” bit for the job.Follow the directions, 1/4” max cut per pass. You could probably go deeper with a larger bit but with the supplies bit, stay with the max cut. (3 passes took about a minute for the circle pictures).Highly recommend.This tool does what it says it will do in a great way. It's easy to use and fast setup and to work with. The base plate is easy to install and provides a bushing and small tool to align it correctly to your router. At first, I didn't understand why it was needed but once you try to install the base plate that comes with it, you understand - if the bit and base plate are not centered correctly, the scale will be inaccurate. The base plate is universal and because of the way the holes are made (they're made to fit just about any router out there), they won't centre on your router like the factory base plate that comes with your router hence the tool to centre it correctly. Takes only a few minutes to setup.The router bit that comes with it is good and could possibly be replaced once it is no longer sharp. (I'm not sure if I would try to get it sharpened but we'll see later...)The drill bit to make the centre hole is also perfect for the provided pivot and the screw that comes with it. You don't get the feel that the hole is too big or too small, it fits perfectly. If you don't want the hole to show through, make sure you drill from underneath your piece of wood (ie: if your piece has a side you would prefer be on top for example) and stop before you punch through.All in all, a good tool at a great price. Highly recommend you get this to make perfect circles. I used to do them by hand and then sand them down but this is way better. The results are excellent and require little or no sanding.Very happy I got this.Hello i purchase this item yesterday when i received i open te box and first is not fitting in mi dewalt router DCW600B Cordless Compact Router and second is missing Mounting Hardware, Drill Bit & Centering Pin. i was able to install the plate with just two screws but isn't centered some one knows how can i contact the seller.
