Drilling SS is not trying to use a screwdriver with it, they are totally different things. Grade dependent you will round off or snap an SS fixing very easily, you’ll have real trouble drilling it especially if the drill slips a little and/or is the slightest bit blunt.
It work hardens in a second, a bit of slip on a drill bit to make it blue and that’s it, you might as well be trying to drill a piece of granite with a carrot.
