Review on 🏼 High Performance 4 Inch Turbo Diamond Grinding Cup Wheel with 12 Segments for Heavy Duty Angle Grinder - Ideal for Concrete Grinding by Simon Connelly

Works well. Used it with a cheap Harbor Freight angle grinder. Even if it doesn't last very long. I used it to grind a quarter to a half inch of concrete in an area of about 5 square feet. At this point it was worn down to a flat base. But for the price it worked great. As others have said, LOTS of dust. I had someone hold the vacuum next to me while I sanded, that helped a bit but still a lot of dust because it was spewing dust around almost 360 degrees. If I had to do it again, I would also buy one of the universal dust covers that you can connect a workshop vacuum cleaner to.
