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

I needed something to smooth out the rough spaces I had by my decking and the wheels were perfect for the job. I was surprised on how long they lasted before i had to change the wheel out. For the price you cant go wrong.

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.

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.

For this price, great deal! Used to prepare glossy tile floor for new tile overlay, looks hardly used after 50’ sq. of removed surface.

Do not buy, bought these bc I had purchased from another seller on Amazon that had great ones. These ones are horrible. Lasted about 10 minutes, if that. Do not buy. Amazon is awesome though they gave my money back!

I had been using flat discs but was working hard to create a flat surface on the bottom of concrete products my wife makes. With a 4 or 4 1/2 flat wheel there is just over an inch of wheel surface to use flat, then its up on edge trying to eyeball the surface. With these and a consistent circular motion of the grinding a large flat surface can be obtained.

Works great, wore down faster than expected but for the money, it did the job nicely

Good product

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
