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

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.

best price for 2 works with angle grinder like a champ
