KSEIBI 644030 Diamond Concrete Grinding Wheel 4 1/2 inch for Polishing and Cleaning Stone Concrete Surface, Cement, Marble, Rock, Granite, and Thinset Removing, Angle Grinder Wheels Cup

Works great. I used this to grind down thinset on a slab after chipping up ceramic tiles. I wet down the thinset to help reduce dust and this worked perfectly to remove the thinset.

Worked so great! Used to grind down my front porch. Can be used for several uses. Easy to attach, fast! GREAT alternative to the expensive ones at lowe's/home depot.

Great item, worked perfecctly.

Worked well! took down the high points in the breakage of concrete.

This wheel is awesome, I was grinding away at my cement to smooth it out for a repair. I had so much dust coming out of my garage that my neighbor came to check on me to make sure my house wasn’t on fire. It will definitely get the job done for you.

I'm using this wheel for lapidary purposes, so probably different than most other people. I use it on the angle grinder to shape larger rocks and it certainly does the trick. As far as fitting on the angel grinder - note this is not a threaded cup wheel - you'll need the nut that comes with your angle grinder to tighten it on. The quality is fantastic. Works great with my 4.5 inch Bauer that I bought from Harbor Freight. As with many tools like this, let the wheel do the work - you don't need to apply a ton of pressure. I'm really happy with it.

Great tool. I needed to grind some masonry and I tried a straight grinder but took forever. This blade ripped through it fast so use caution as you can easily remove too much.

We used this cutter to remove leftover thinset after hammering the bulk of the thinset off. While it was capable of the job, it removed thinset for about 6 sq ft before the wheel just polished the concrete. Because of the shallow cup to the wheel, I had to add shims to my universal dust shroud I added to my grinder.
