Review on DEWALT DW4524 4.5-Inch x 0.25-Inch x 0.875-Inch Concrete/Masonry Grinding Wheel by Julio Black

I bought this wheel to sand down sidewalks that have been damaged/raised by a tree root. It works well. You have to keep it moving or it could dig into the concrete. A lot of dust is generated when grinding concrete. I could hold the mill so the dust would move away from me. Every breeze brings it back because it's very fine dust. I was prepared with goggles and a dust mask. But I had to go back to the garage for earplugs, it's noisy. You need to give it some power to really take the concrete off. I tried to take my time and do a good job. I could sand some more and put some patching material in the crack. The secret for me was to keep moving it back and forth over the area I was trying to remove and it came out really smooth. No one will trip over this crack. Best $4 I've spent in a long time.
