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.

I used this product to grind paint off of a smooth concrete block foundation. 1 wheel removed about 40 sq ft. of paint down to bare block.

I needed something that would chew through large roots that are higher than ground level. A YouTube video led me to this design. Oh wow! This is an amazing find. These puppies are sharp and do a great job! Would fully recommend for a job like mine.

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

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.

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.

Does not grind concrete, it only makes scrapes !

Did a great job removing paint from cement porch.

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

works well on rocks
