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

These grinding wheels wort great but they do wear down faster than the higher priced one. but they did the job at half the price.

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

Did my garage with 1 but purchased 3

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.

Very aggressive. Took down granite and flag a stone quickly

The embedded diamonds are spars and straite the concrete as you grind it. If youre just rough grinding, and dont need them to last very long, these work well enough.

Description says 2 but I only got 1.

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 purchased these grinding cups to remove about 100 sq ft of tile mortar from my concrete basement floor. I use these cups on a 4 1/2 inch black and decker corded angle grinder with a cheap dust shroud. The quality for the value on these is great. Each cup took off approximately 50 ft.² of mortar.

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