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

This tool grinds cement very quickly and levels concrete in minutes depending on the size of your project. and you have to make them move in all directions to make it nice and smooth and flat. After that you need to reseal your concrete. You will be really surprised at how much is created with the first use. That shouldn't be a problem, but it really seems to surprise you every time you use it. You can use it wet with plenty of water, or better yet, use a good vacuum with a vacuum attachment. I definitely recommend wearing a Tyvek suit and a respirator or a dust mask and a vacuum as the cement dust will clog your lungs and turn you into a ghost.
