FEWELL4 1/2” Concrete Grinding Wheel, Double Row Diamond Cup Wheel with 7/8” Arbor for Polishing and Grinding Concrete Surface Brick Stone Marble Cement Granite

Worked great for grinding concrete, was very impressed on how well it worked.

Used it to grind a raised concrete driveway apron lip that was retaining rain water with a cordless angle grinder. Cordless, as I was using a hose to keep the concrete slightly wet and not have choking dust (so I had messy slurry instead). Ground quick and smooth, looks like no wear to the grinding wheel, too.

Can't beat the performance of this grinding wheel, and the price is great too!

Hubby ordered this to grind down a piece of our walkway that was raised due to a tree root (which caused my dad to trip and fall)It worked just as expected and he was able to grind down the section without any issues.I only posted 4 stars because I don't know much about tools. But I know my hubby was very happy with this tool/accessory.

Best concrete wheel I have ever used. An hour of use and shows no wear !! I had to remove the guard to git it to fit the Ryobi 18V grinder, no big deal.

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.

This wheel is harsh to use. The design of the teeth makes it jump around while spinning instead of digging into the concrete. It is terrible, I will only use the swirl designed teeth from now on.

The wheel ground down a high point in my concrete walk that was lifted by tree roots. Easy to use and seems to have held up well after 45 minutes of continuous use.
