Glad it worked,
You might also invest in the purple cobalt drills from McMaster Carr they are made especially for drilling stainless. They are not inexpensive but I keep them on board when all else fails. I also use the dam technique when drilling stainless and fill it with drilling oil for stainless also from McMaster.

Another success for your dam technique! Thanks for the suggestion.
I had a 5mm machine screw that I had almost given up on getting out in one piece. Not only was it a stainless screw corroded into aluminum, but it had also been sheared, and was bent, jamming the threads for that extra measure of difficulty. And it’s not big enough to really lean on without breaking. Oil, heat, pressure, over and over, and not so much as a wiggle.
I didn’t have any “duct seal” so I improvised by making a stiff dough of flour and water for the dam. It wasn’t perfect, but it worked. After twenty-four hours of soaking in a puddle of PB Blaster, the screw backed out easily. I can see using this often in my future.
