Review on DEWALT Diamond Cup Grinding Wheel, 4-Inch (DW4772T): Ultimate Precision and Long-Lasting Performance by Mike Bucher

This thing really works! It is very aggressive and quickly abrades masonry. I tried to keep the angle grinder as level as possible so the wear on the pads was even, but they held up pretty well. This kicks up a lot of dust. So if you can get the area wet and keep it moist, the dust will be greatly reduced (and probably extend the life of the wheel). Just be careful with water near the power tool. The only thing I would like to change is that the pads don't go back as far because they would be difficult to use this far and a few more would have helped extend the life. For the price, however, it is unbeatable and performs significantly better than SiC grinding wheels. Made in China.
