 @67975218 diamond will cut anything. the only thing idk about is aluminum- it may gum up the wheel. you'd have to try it out.  diamond can cut steel though.

certain abrasives work best on different materials- AlO2 (the black ones) are good for steel. aluminum gums them up

 @67975218 what you're talking about is "climb" vs "conventional" cutting direction.  for hand held tools you generally want to use conventional cutting. meaning, you're pushing against the direction of force rather than with it.

reason being a "climb" cut has a tendency to get away from you by climbing onto the work
