Cutting shower rod

n0c7

I just purchased two new Moen metal curved hotel style shower rods designed to fit in a 59"-60" opening. Both of the areas where I want to mount these are tiled, and both are slightly smaller than the required width due to the grout and width of the tiles.

I need to trim both of the rods on the same existing angle. I have a decent miter saw but I'm not sure which blade to use on this type of metal. Will a 80-100 teeth dent blade work? Also, any tips for clamping down such an awkward piece while I cut it?

These are probably steel rods. Use a hacksaw and file it smooth.
