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.

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

Weak

I used one of these grinding wheels to level out some uneven concrete. They ground it down very well, taking off even more material in a shorter time than I would have expected. A good value also.Highly recommended.

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.

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.

To fix an area of concrete floor.

Did a good job sanding my concrete countertops.

Good purchase!

Doesnt fit. free return drop off only!. So now I have to spend money in gas to return....
