[2021 Upgraded] 2 Pack Diamond Cup Grinding Wheel Set - Double Row Concrete Grinding Wheel for Angle Grinder - Heavy Duty 4-1/2 Inch & 4 Inch Wheels - Perfect for Polishing (Gold) Review

This product is great for removing cement in my garage before painting the floor with cement stain. Thank you Patrick D!

I bought these to clean out a hole I cut in a concrete block wall. Using it with a 4 1/2" angle grinder made the job a breeze. Dust is everywhere, but a satisfying job is done quickly.

This product cut 5 square feet of tile adhesive coated concrete, that's it, stopped cutting, bought Dewalt for $59 and finished the rest of the bathroom. and there is still a lot of life in it.

Will buy again, 5 inch 2 row slicer works very well. You're still cutting concrete, but these cutters work to remove a lot of material in a short amount of time. Wear eye and dust protection and have fun.

The material on these wheels feels solid. Unfortunately the 4-1/2" won't fit my Ryobi angle grinder with the guard installed. I will not compromise safety by grinding without a guard. Returned.

The previous owner of my home painted the floor of my two car garage. I used them to grind it down to clean concrete and didn't even burn any of them when I was done. Considering that a mug costs three times as much in the local store, I am very happy with the purchase.
