My experience with stainless sinks are that they are pretty cheap
stainless. I drilled mine with a hole saw- no problem. They cut a
little rough but most sink holes have- jeez I'm getting old, I forgot
the word- rings around the things that go in the holes that cover the
edges of the hole. A mind is such a terrible thing to lose. Will you
visit me in the old folks home?

Greenlee makes punch sets that you operate with a wrench - that should
work much better than a large diameter drill bit. You might DAGS to
find a distributer...

Known as a Chassis Punch. WW Grainger has them per an old catalog,
probably about $40.
Good for 10 ga max.
Just go slow, that's what my brother-out-law says (he's a plumber). If your
tool goes too fast and it heats up, the s/s will harden.
Using this advice I've used both my tungsten steel holesaw and the jigsaw
successfully as well as drills.

Hole saw, use lubrication like a penetrating oil..Blaster, WD-40.. Go slow.
Keep the tool as perpendicular as possible to the work surface. When it
starts to break through it will tend to grab when cutting thin metal.
Light feed pressure will reduce the occurence of finger and wrist repair
due to the sudden spin/acceleration of the drill motor in the opposite
You've probably got this done by now, but in my experience hole saws
to metal don't work too well. I think it comes down to what the
finished hole will look like. With a hole saw I have always had the
issue that the final hole has some scrape marks around it where the
teeth touched the metal. I'm not saying it's impossible to get a nice
hole like the other posters. But if I were doing what you are and want
a nice clean hole I'd use a punch. Those tapered bits that were
mentioned are another option I've never personally used one, but have
worked side by side with some that have and the holes those leave also
aren't bad. Keep in mind any hole you cut in metal should be filed and
will not come out as clean as something that was water jetted or cut
with other industrial processes.
And for the WD-40 replies. This is directly from the manufacturers
website: "With literally thousands of uses, WD-40 is the #1
multi-purpose problem solver. It cleans, protects, penetrates,
lubricates and displaces moisture like no other product on earth."
