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

I received my order today and when I saw the discs, they are extremely thin. Im going to try them out, however I dont expect them to perform as good as they say. Ill follow up afterwards.

Good price great item fast shipping

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

I started grinding masonry paint off the exterior of my house foundation with a $45 brand name grinding wheel. I ground the teeth off the wheel in about 24 square feet. These wheels cost under $5 each and last for about 15 square feet. Thats $2 per sq. ft. vs. 33 cents per sq. ft., so I save a lot by having to swap these grinding wheels a little more frequently. I have noticed these wheels last longer if you dont grind constantly. They seem to wear faster when you get them really hot.

I form rocks for tumbling this works so well it is unbelievable

Good product

Cant beat this price and these things grind like beasts even when youre scraping down to the metal. Should have bought more

Cant beat it for this price

I cant recommend this for a large project, but its good enough for a small project, like taking the edge off of uneven concrete walkway. It takes some repeated back-and-forth, but it does the job.

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