Review on 🔸 Pack of 2 Erduoduo 4 Inch Diamond Cup Grinding Wheels with 12 Segments for Heavy Duty Angle Grinders by Roel Lebron

I had to remove about 3/4 inch of concrete that was taped to an old concrete footing. The new concrete, which was applied to the old concrete foundation, was frictionally connected. I couldn't cancel it. Grinding was the only method of removal. 4 sq feet of 3/4 inch removable stock. I ended up using both grinding wheels and each had some use left. I saved them in case I need to remove additional footage. I was very impressed with their performance.
