sansheng 4 Pieces Concrete Grinding Wheel 4 inch,Diamond Cup Wheel Angle Grinder Wheels Grinding of Concrete, Granite

Good quality

ground down a couple of “kickers” at sidewalk joints with a cheap grinder...easy to use, works quickly and seems to have plenty of life left...I strongly suggest wearing ear and ear protection

This grinding wheel worked great! I used it to grind down a ledge on my sidewalk. It was a decent ledge and this thing ate it up. I would 100% reccomend it.

The center ring was off when i received it

Excellent product. I removed the paint from my concrete patio in short (but extremely dusty) order with little or no wear to the blades.

Amazing product. Long lasting. Great results. Redone my 20 years old garage floor with a lot of cracks and issues. More expensive products didnt last as long.

We used these to remove about 6 sq ft of thinset from our basement floor. The thinset was almost a 1/4 inch thick in some areas. These discs got through it with not issues at all. We did go through 3 of the discs, but that was expected with as much material we were removing.

I received my order today and when I saw the discs, they are extremely thin. Im going to try them out, however I dont expect them to perform as good as they say. Ill follow up afterwards.

The grinding wheel is well made, durable and produces a very nice finish. Im very pleased with the purchase.

This concrete grinder was awesome. Before I burned out a cheap harbor freight grinder this thing was grinding the concrete away with no issues. When I had finished this grinder attachment looked like it had hardly broken a sweet and was ready for more.
