If you're using a concrete floor grinder on a coarse surface, you want a diamond with a coarser grit (30 to 40 should do the trick). If you want to polish your surface, you'll need a tool with higher grit. Anything above a 40 grit will give you a smoother surface. Keep in mind that higher grit grinding cup wheels take longer to use.
