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

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.

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!

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.

I needed something that would chew through large roots that are higher than ground level. A YouTube video led me to this design. Oh wow! This is an amazing find. These puppies are sharp and do a great job! Would fully recommend for a job like mine.

The product worked like a champ eating through the concrete. No issues for mine.

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.

Perfect

Does not grind concrete, it only makes scrapes !
