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

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.

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

Perfect

Longevidad!

These do the job but I have no idea how long they will last. One thing I noted immediately was any paint they come in contact with will clog the cutting surface and must be scrapped off to continue.

The embedded diamonds are spars and straite the concrete as you grind it. If youre just rough grinding, and dont need them to last very long, these work well enough.

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.

Work so well I am ordering more

I have a cheap angle grinder but with this wheel I was able to smooth over a concrete crack repair job cutting down both new and old concrete with ease. Job well done.

Good Product
