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

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.

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

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

They ground down 2 spots for a railing installation

Description says 2 but I only got 1.

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

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.

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.

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.

Good value. Works as intended with a predictable life.
