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

Works great for leveling out high spots on concrete patios.

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!

it is okay and gt the job done it you need it for a small job and wont need it for one or two small jobs. Otherwise it wont last and it becomes much expensive than a quality product. it comes with a shim which was useless for me. There are variety of angle grinders out there which requires different shimming. It would be nice to provide a few shimming option along the wheel. Since only one shimming washer included in, it is on you to go find something fit in your tool and this wheel if you can which is frustrating. Reputable brands fits much better without guess work. At the end to me this grinding wheel is waste of money. I whish I spend a little more and get a better 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.

POORLY QUALITY AND INFERIOR FINISH - WEARS OFF COMPLETELY INLY AFTER 3-4 MNUTES OF USE. DOES NOT FIT PROPERLY ANY OF THE NAME BRAND ANGLE GRINDERS. POOR QUALITY.
