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

This was perfect size for the concrete edges and rough spots on my house base I wanted to cover.

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.

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

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!
