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

Worked great at grinding my garage and drive way concrete to even out the surface.

This removed the high side from a crack in my garage floor, about 6 feet long with a high side of 1/4-inch in less that 15 minutes.

Bought this two pack to remove tile morter from underlayment. Used a 4 1/2 inch angle grinder fitted with a dust shield and shop vac. Removed 200 square feet of morter using one wheel! Wheel still has some life left. Very satisfied.

Works great to remove concrete and glue from subfloor. Hard to mount on angle grinder, may never get it off.

Very aggressive. Took down granite and flag a stone quickly

when i orderd the grinding wheels i forgot to measure the shaft on my makita grinder, so the holes in the grinder disc are a bit large. am trying to find a way to make the disc work with my grinder which has a shaft of .615 diameter and the holes in the grinding disc measure .80 diameter.

Dont buy these they dont work on a 4 1/2 grinder the cup is to small for the nut and they dont have much diamond in the blade didnt grind at all

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

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.

After modifying the grinder vacuum head and the right size spacers I started grinding on my rough basement wall and it worked excellent. Took down high spots, nubs and concrete blobs on the wall pretty fast and easy. I didnt have to put much pressure at all, it just ground it down nice and smooth. Im happy with them, got the two pack at a good price and they work great.
