A good grinder hand can do good work with just about any wheel on steel. There are a lot of different variables from wheel speed to longitudinal speed, cross feed step over, depth of cut, coolant or not or which one, and each of them can make a noticable difference. It is truly an art. Something that is often said is hard wheels for soft metal, soft wheels for hard metal. A good grinder hand can get about as good of a finish with a coarse wheel as with a fine wheel. Amazingly, much of it is in the fine details of how and when the wheel is dressed. I sure wish I could learn all that knowledge gathered in a long career by watching a couple YouTube videos...
