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

Good product for price! Better price than box stores and same quality

These are sad. You get what you pay for I guess. Each segment on the wheel had about 4 diamonds. The wore down quickly and didnt do much grinding. Spend more money and buy quality. Your job will be less frustrating.

Did a good job sanding my concrete countertops.

Worked great at grinding my garage and drive way concrete to even out the surface.

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

Good purchase!

To fix an area of concrete floor.

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.

These worked great on my front porch, dry iced that old paint and chips flew off like confetti. Very little scouring of the mortar. Only halfway done with one disc, and thats on thick paint. Dont know if its the dry ice or the disc, but the disc last awhile. Good buy for the buck.
