Using a hole saw to cut holes through metal can be difficult and dangerous if you do not know how to use the drill’s safety features. This video shows how to cut a 1 ¾” hole in some 1/4 inch mild steel. It's important to use a coolant/lubricant when doing this to prevent the holesaw from over heating.
