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

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.

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 had to make some spacers to get them on a very old makita side grinder and remove the safety guard but they worked great. Safety shield and heavy gloves an absolute must!

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

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

Had to grind some filed stone around our front door way. Grinding wheel fit right into the angle grinder and worked very well and quickly to remove the stone needed for the clearance we desired. Appreciate the quick shipment and quality of grinding wheels. Lots of material left for future projects!

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.
