Circle Cutting Jig for Routers/Trimmers Electric Hand Circle Groove （No Pre-drilled Holes）

This is a well made kit that lacks instructions. So here is what you need to know:1. The included drill bit is for the pilot hole in the center of the circle. If you want to make a table or another item without a hole going through it, then use the included metal collar with set screw to limit the depth to the length of the pin (pivot point) on the metal bar.2. The included bit will not fit your router, it is only for the pilot hole. You will need a straight router bit, preferably carbide.3. The two short rods with threads and a hex socket are not for cutting circles, they are for centering holes/mortises in wood boards.4. Unless your router fits in the existing holes on the jig, you will need to drill holes (drill press recommended) as needed for your router. The metal pin (used as a temporary router bit) and white plastic disk are used to center the router in the jig, then holes are drilled as needed. Screws are included, use a drill bit just slightly smaller than the thread diameter and they will self-tap with a screw driver and hold the router on the jig.5. Once the router is mounted on the jig, insert your router bit and attach the metal bar with the pin on it (make sure the pin is on tight) to the grove on the bottom side of the jig (pin facing down) so that the length from the center of the pin to the inner edge (outside cuts) or outer edge (inside cuts) is as desired. Use the plastic knob to lock the bar at the desired position. Tighten firmly, if it slips, the circle with be distorted. I used pliers, but be careful not to break the knob.6. Set the depth of cut for the router to about a quarter inch or less and make the first cut, rotating the router around the pivot point clockwise. Clear the sawdust. Readjust the bit depth in increments and continue cutting. On the last pass make sure the work can't move if you are making inside cuts or rings. Otherwise the bit may cut into your work.That's it! Good luck.

Update: raised the review to 5 stars. I have used this for a year and it is great every time I need it. It came with everything but the router and router bit.Setting up takes a little work and precision as I had to drill holes for the little Bosch router I use. It was easy enough once I got the right size bit. Do yourself a favor and take your time and get the screw holes right. There is no trick, just try out some drill bits to make sure the hole is as close as possible and maybe a tiny bit smaller but not bigger.Good deal on this, happy to have it in the box of router jigs.2019 I was attracted to the $30 price point and am impressed with the fit and finish. The device it flat and the parts that come with it are all present. There is another review here on how to use it, I’ll study that one, give it a whirl, and report back here. If you are on the fence you may want to give this one a try.

I matched this to a DeWalt trim router and cut my first hole in minutes. I had to mark, drill and countersink holes in the plate but that was very straight forward. You could obviously make your own circle cutting jig but this one is well designed and works as expected. The bolts that came with the plate even fit the DeWalt router base, something I didn't expect.

I used this circle cutting jig to cut a circular recess in some plywood, it worked great once you set it up. I was using it with my compact router and followed the directions to trace my baseplate onto their base. It is made of Bakelite and so I was able to easily drill through holes and a recessed hole with a Forster bit for the mounting screw. This particular jig allows you to crest really small circles and that is why I decided on this one. I would recommend this product for anyone who is handy and can drill perpendicular holes which is key.

Great jig to have. Once you get your router on the tool its super easy to cut circles. In reviews it said it worked with Milwaukee compact router perfectly but that's not the case, one hole does and you real gotta mess with it to get the router lined up right and then drill the holes. Once it's on though it's an awesome tool to have.

Great little jig, works flawlessly, just know when you buy this... it is universal and drilling will be required to mount your small rotor as there are no holes for mounting at all. But, if your buying a rotor jig and do the type of work that requires a rotor... I am sure setting up plate and drilling mounting hold is easy work. "This is not for the novice" as mounting needs to be perfect so there is no offset vibrations as that can cause serious injuries!

It is ok had to make modification to fit my router and to make it work without moving while cutting circles. But with patience it does ok

I think this circle cutter has potential to be a good tool. However there were NO instructions on how to use it or even attach a router to it. Very little information on-line, just a few youtube videos by others who have purchased it.Additionally, you must drill your own mounting holes in the base and somehow figure out how to adapt your router to it. It would be 100% better if it came with a universal adapter to mount routers. The bottom line is that by the time you figure out how to adapt it and then get a router mounted, you could have made your own simple circle cutter.
