Concrete grinding diamonds are available in a wide variety of shapes, sizes, and strengths. Size is classified by the mesh or grit number, although a large diamond has a small number (18/20), while a smaller diamond has a larger number (80/100 or 170/200, for example). While larger diamonds are used to expose the aggregate, smaller diamonds ...
