Wood Turbo Carving Disc (Curve) 90mm in 6 Teeth by KOWOOD

I was pleasantly surprised how well this works. There is a learning curve of just to get The correct angle and your speed correct. Absolutely were safety gear. This thing throws Little wood chips out with some velocity.. let the weight of your tool and your grinder do the work just get a good firm grip on it. I found it best to work in short one foot sections. It took me maybe 20 minutes to do these four post. And that was just me experimenting and trying to get used to the tool. With each post I got faster.

I installed the carving disk on my least expensive angle grinder as a test. For my application I had to use a worn out cutting disk as a shim or washer on the grinder shaft first so the carving disk was tight. This thing cuts like crazy. I showed it no mercy and it still works. When it eventually wears out I will buy another one. I intend to always have one of these disks on my beater grinder for tough projects.The disk quickly ground off roots that were playing havoc with my mower. It is also being used along with other tools to get a large River Birch stump below grade so I can mow over it. Unlike a chainsaw this tool keeps on cutting where there is a little dirt. Impressive !!!Please use the guard on your grinder and appropriate safety equipment for your protection. This is not a toy and it could hurt you badly if not used properly.Update: The cutter found a piece of gravel in the stump wood. It made a terrible sound, but after prying out the stone out, it just kept on cutting as before. Next will be the pine roots in the back yard. I have gotten more than my money's worth out of this disk already, and it keeps on cutting. What a great tool.

Primarily my fault I guess, but after watching the videos I thought the one I purchased was for at least a 4" grinder but apparently the page defaulted to the 90mm smaller one and so it does not fit on the spindle of my 4 1/2" bosch grinder... maybe the video reviews are the 103mm version? Is the diameter of the center hole big enough for a standard 4 1/2" grinder, maybe... oh well, just a minor complaint, I haven't used it so I can't attest to quality but don't get the 90mm one if you have a regular 4 1/2 grinder. Thing is inky dinky.

I use this for grinding down roots from the trees in my yard, so they don't hit my lawnmower's blade. Works great for that!!! Solidly built. You'd never know I even used it and I've put this thing through hell and there's hardly a mark on it. The blades aren't showing any wear at all and I'm hitting dirt and rocks here and there with no nicks or dents or chips to show for it at all!!! Cuts right through wood like butter unless the wood is super wet (maple) then it's a little bit harder, but will still do the job, it just takes more time and passes.

I had some wicked tree roots bulging up from my grass that were starting to catch the edge of my mower deck.This wheel ground them away like butter! I was very surprised how smooth and fast it went. From the look of it I was expecting a lot of vibration and bucking, but there was none of that. Just make sure to use both hands on the tool and be aware of where your body is in relation to the tool in case it does buck.This fit my Makita 9564CV 4-1/2" angle grinder with no problem. Did not need a special nut. Also fit my old POS harbor-freight grinder no problem.I used the medium setting on the Makita, about 6500rpm.

did not fit right.

Very solid , very handy blade for grinder. As others have stated, did not fit on grinder out of the box. I worked pretty hard to find a "work around". Mandrel that comes with grinder is too big. Be willing to jump those hoops, and Its worth it. Soo..... you decide.

The 103mm wheel fits perfectly on my Milwaukee 4.5” grinder with the original arbor nuts. No special adapter needed. Cuts through wood quite well. It’s not as hard to control as I thought based on other reviews. It’s not meant to provide a finished surface, it’s meant to hog out wood. I’m right handed but I found holding the grinder with my left hand and the handle with my right hand was a bit easier to control. All in all a good tool and well worth the price.
