Jig worked great for the project I purchased it fop. The bit felt cheap when I opened the box and sure enough, it broke its first time out.

This is my second time purchasing this tool because I misplaced the first one. I used this to cut out round speaker holes for both HDF boards and ceiling boards. Of course HDF board take longer time to cut and after a couple of wholes (6" diameter) the cutting drill bit became somewhat dull. Cutting the ceiling boards is like cutting butter with a sharp knife, very easy and accurate cuts. It takes a little practice to figure out how to setup the position of the drill bit to a precise cut, but once you figured it out, it's pretty easy to setup. I recommend this tool.

Using this circle cutter with straight edge guide is a great way to turn your dremel into an even more valuable power tool. The circle cutter has worked flawlessly cutting very clean and quick circles/holes. The alternative is to purchase very expensive hole saws that require a major drill for the larger and deeper holes. The dremel and spiral saw bit will allow you to cut very large holes quickly. Set up is a snap and the center point adjustment is super easy to set without any special tools. The hole sizing gauge is a bit general, but if you need a precisely sized hole, I use a tape measure to set the radius by measuring from the far side of the spiral bit to the center of the pivot point. The straight edge guide turns your dremel into a small router that you can use to do all sorts of helpful cuts. Often, whenever I am away from my router table, this is my go to tool for cutting a small and simple dado or rabbit, or cleaning up an edge. I love this attachment!

I am so thankful I finally found one of these Dremel accessory attachments circle cutters I have been needing something like this for so long I did not want to spend an arm and a leg to buy a router and in my artwork I am constantly needing to cut circles either out of the center of a piece of wood or cutting an outer circle into a piece of wood I have three different dremels and I thought surely this thing will fit on one of them I was a little concerned about the sturdiness of the wood cutting bit that came with it because I was cutting through an half inch piece of plywood however after I set it up and started my pilot holes and started cutting into the circle of wood it went smoothly the bit held up great and I cut a perfect circle out of the center of my wood I even turned around and tried it on a plastic decorative plate and it worked great on there so I would highly highly recommend this accessory if you are needing to cut circles and you don't want to spend an arm and a leg on a humongous expensive router this definitely worked I even bought a couple of extra wood cutting drill bits for my Dremel which is always good to have on hand because you never know when you'll break one but overall this was a great great buy for an excellent price

I used this to cut holes into 1/8" MDF board as a template and two 6061 aluminum 1/4" sheets. You really have to make sure all the screws are securely tightened otherwise you will get a lot of wiggling. Don't use this if you actually need to use the circles. The actual hole is cut more accurately than the leftover material. You are more likely to ruin the circles than the holes. Take it slow and hold the tool tightly otherwise the Dremel bit can get caught on the material and ruin your cut. The bit that comes with the tool eats through wood very easily but if you are working with metal you have to be patient and take it extra slow otherwise you can break the bit.The description says you can cut as small as 3/4" in diameter but the smallest I was able to cut with this was a little over 2" in Diameter. The screws on the tool retainer get in the way of the center pin making the tool really wobbly and unstable if I go smaller than 2".The plastic holder that you screw your tool into is very thin and will easily split if you accidentally over tighten your tool. Also the mechanism used to adjust the height of the tool is kind of flimsy and doesn't feel very secure. I got a lot of vibration in the tool if I set the height too high but that could also be because I was primarily working with 6061 Aluminum.Overall its decent if you need something quick and cheap but for anything that needs serious work just get a drill press or better yet a router. It will save you a lot of time and will produce better quality work.
