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

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.

Longevidad!

The description says 2. Why show 4?

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.

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

So much better then the $35 each ones I’ve purchased in the past. Great value.

These are sad. You get what you pay for I guess. Each segment on the wheel had about 4 diamonds. The wore down quickly and didnt do much grinding. Spend more money and buy quality. Your job will be less frustrating.

best price for 2 works with angle grinder like a champ

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.

Might take a few of these to do what you want to do as they seem to wear faster than I thought they would, but they do work well while they last.. One wore out in about 15 mins of smoothing old concrete edges
