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

Works well, almost no wear after 30 minutes use on mortar, concrete, stone,

Worked great. Grinder an entire garage floor with one blade and it hardly shows any wear.

used for sanding my concrete pool, worked perfect good quality.

I used these blades with a dust shroud to remove stubborn thinset. The listed dimension of back to blade is not 0.92. Its closer to to 3/4. My dust shroud is about 1 to bristles so I was having to push to get the blade to cut. I used 3 on an 80qft job because the blade rounded as I couldnt cut flat.

Great for the price, also work very well. Talking of around the house, not professional to judge..

I used it to grind down about 150 sf of my concrete porch that had uneven and damaged concrete, prior to resurfacing it. This disk made the job so easy. Make sure to wear a mask and eye protection because you’ll make a lot of dust and things will be flying all over. Beat part is, after all this grinding I still have about 90% life left on the disk!!

Cant beat it for this price

The center ring was off when i received it

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

It worked and was easy to install to my grinder. I grind paint off from cement in my sunroom.
