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

The grinding wheel is well made, durable and produces a very nice finish. Im very pleased with the purchase.

used for sanding my concrete pool, worked perfect good quality.

Good price great item fast shipping

works great

I was skeptical about this grinding wheel because of the low price, but it works great! I ground a 1 lip off a 3ft wide concrete walkway in less than 15 minutes using a $15 Harbor Freight angle grinder. (Use those 20% off coupons :-) Wheel doesnt even look worn at all.

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

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!

Cant beat it for this price

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.

Did not expect to complete the work in a short time.
