As smooth as butter!
it did cut through concrete and red brick without any cracking. Used with wet, results look great. Dust level is max without water but that's to be expected.

Good value finer grind.
I got this as it was a much better price than some other diamond wheels I use and we use a lot of them. It's the finer grit of the ones available which is what I wanted. It is not too aggressive but removed material well without being too aggressive. Works well on my Milwaulkee & Hilti Grinders. I'd recommend for finish grinding not aggressive removal grinding.

Highly Recommend
works well on uneven concrete but be careful this will eat it away quickly. I let the weight of the grinder do the work and it gets the job done. The shape keeps it in the work area as needed and definitely recommend. Being concrete my job was a 20' long crack I wanted to level out and fill in. It went through 1/2 the thickness of the plates but worked well.

It worked great for my application
I was laying rubber mats on a cement pad that had been finished with a broom and there were ridges that prevented the mats from meeting flush. I was just knocking those down and this made quick work of them. A free warning tip, its very dusty. I can't speak to the longevity but it handled my job in minutes.

Works great
I bought this for some pavers I laid. I had to grind off the edges of about 600 pavers. Plus I had to level part of a sidewalk. Still going string and impressed for the price.

Terrific Concrete Grinding Disc
I bought this grinding disc to grind down the ugly fake flagstone that was previously layered on top of the original concrete steps. I had started with a small 4" grinding wheel that was good but this one is far superior in getting it done smoother and quicker. Although I haven't completed the job yet, I am really pleased with how this one is working. Just don't leave it in one spot, keep the grinder moving. I will still have to use the 4" for the riser part but the rest of the job I will use this 7" one. I paired this up with a 15 amp Bosch angle grinder that has loads of power to spin this disc. I bought a dust shroud to use with this disc but it couldn't contain the dust. The photo is my front steps showing the partial completion.
