Erduoduo 2 Pack 4 Inch Diamond Cup Grinding Wheel 12 Segs Heavy Duty Angle Grinder Wheels for Angle Grinder

I had to remove about 3/4 of concrete bonded to an older concrete foundation. The newer concrete added over the older concrete foundation was securely bonded. I could not chip it off. Grinding was the only method for removal. I had about 4 sqft of 3/4 material to remove. I ended up using both grinding wheels and each still has some amount of usefulness left. I kept them just in case I needed to remove anymore material. I was very impressed with how they performed.

Compared to the expensive disks these are a great value for cheap

Attempted to use to remove thinset from concrete. Hardly any diamonds on the cutting wheel, was barely removing product, job would have taken forever. Not worth the hassle. ended up buying a Norton wheel for $45, cut right through the thinset no problem.

Good purchase!

El articulo resulto muy pequeño no como se veia en la foto.

These grinding wheels wort great but they do wear down faster than the higher priced one. but they did the job at half the price.
