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

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

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.

They are extremely less costly and they really smooth the concrete.

item as I needed Thank you

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

Works great! No complaints. If you have a one time job just buy 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

did just what I needed it to do. very good quality.

It went through three harbor freight angle grinders before I was done and it still has a lot of life left. Im glad the store is so close and they take returns.

The center ring was off when i received it
