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

I needed something to smooth out the rough spaces I had by my decking and the wheels were perfect for the job. I was surprised on how long they lasted before i had to change the wheel out. For the price you cant go wrong.

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.

I used these blades with a dust shroud to remove stubborn thinset. The listed dimension of back to blade is not 0.92. Its closer to to 3/4. My dust shroud is about 1 to bristles so I was having to push to get the blade to cut. I used 3 on an 80qft job because the blade rounded as I couldnt cut flat.

Worked great. One disc lasted for about 1500 square feet on 50+ year old concrete. Cut nicely and smoothly. Use in conjunction with a dust shroud and vacuum.

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

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.

Very good price. Fast shipping.

Works so well!!!! Much faster than other discs.

Good price great item fast shipping
