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

I used four of these on an apox. 10 by 20ft. Sunroom to remove carpet glue from concrete floor. These will slightly eat into the concrete, so I plan on renting a concrete polisher to finish it before I start coating it with apoxy sealer. I strongly recommend a vacuum shroud to remove dust.

Cut the granite like hot butter

Sent it back wobble , unbalanced

Did a good job sanding my concrete countertops.

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.

Work so well I am ordering more
