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

best price for 2 works with angle grinder like a champ

Good item and good product

I bought these to level out some cracked concrete for a patch and they are quite effective.

I used this product to grind paint off of a smooth concrete block foundation. 1 wheel removed about 40 sq ft. of paint down to bare block.

The product worked like a champ eating through the concrete. No issues for mine.

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.

The description says 2. Why show 4?

I only received one grinding disc total. I did not get what I payed for.

Very aggressive. Took down granite and flag a stone quickly

I used four of these on an apox. 10 by 20ft. Sunroom to remove carpet glue from concrete floor. These will slightly eat into the concrete, so I plan on renting a concrete polisher to finish it before I start coating it with apoxy sealer. I strongly recommend a vacuum shroud to remove dust.
