FEWELL 4 1/2” Concrete Grinding Wheel, Double Row Diamond Cup Wheel with 7/8” Arbor for Polishing and Grinding Concrete Surface Brick Stone Marble...

Fewell 4 1/2 Concrete Grinding Wheel; I have some uneven edged of concrete patio slabs that I thought this might be just the thing to use to deal with them; so, I decided to try it. The safety sheet is in English and German; and this line jumped out at me; "Make sure the speed does NOT exceed maximum operating speed marked on the wheel" I had to go to the ZeeBooth listing to see what was printed on mine. Very hard to read. This disk's max speed is 13300; well above the 11000 of my Bosh X-Lock angle grinder. And, It fits my Dreyoo Grinder X-Lock to 5/8''-11 - 7/8 inch adapter perfectly. We ordered a metal sculpture for the front yard; and I planed to secure it with a concrete pier block. We also planned to light it using a well light. When I dry fitted everything in place; the wire to the light was pinched between the metal, and the concrete block. I saw I could fix that by cutting a groove for the wire; and realized this wheel might be my best tool. It did a great job very quickly with a nice smooth edge on the side that I guided it away from me. I discovered you must not pull it back when I did the other side; so not so pretty. I did make a few passes to fix my mistake. The whole time was less than 10 minutes; and the wheel still looked brant new when I washed the grit off. I'll update this when I do the patio slabs; but I think it is a great DIY tool to have on hand.

Had to grind concrete. Put this wheel on my cordless side grinder and put it through the paces! It ground the concrete almost like butter. It shorten my grinding time. Very pleased with this product!

I used this to remove tile Thinset. It worked great! Fast and effective. Low cost! Similar item at Harbor Freight cost $40-$59. It worked on a Dewalt angle grinder (perfect fit). I was done removing Thinset in bathroom and toilet area quickly. If you are not a professional but need this tool, don't hesitate to purchase. I don't know how long it last or durable it is but it is perfect for small to medium size job.

I haven't tried it on brick or stone, but if you need to grind some surface off a piece of concrete, this will work just fine. I put it on my 4 1/2" portable grinder and needed to level off a few high edges on my sidewalk. Worked like a charm. Took it off pretty easily. Better wear a mask because it'll generate a lot of dust. Can't speak for the longterm durability, but it worked pretty well on my sidewalk.

Diamond cup wheels are one of those things at the store that when you see the price, you wonder if it's actually made of of diamonds. Even at Harbor Freight where the equivalent of this wheel is $50. For less than a 1/3 of that price, I was expecting a wheel without much material on it. I was wrong, there's actually MORE material on this disc which means MORE life. This was a nice surprise. The only real difference is that this wheel isn't threaded. Material removal is as expected-you can be aggressive or with some finesse get a nice, flat concrete finish. With as much material as this wheel has, I expect to get quite a bit of use out of it. This was a great find. I hate grinding concrete so hopefully its a long time until I need another one.
