Not sure if you have an IKEA store near you but they sell a sink knockout
kit for $20.00, includes a Greenlee style punch and a mini tubing cutter.

Punched 4 extra knock outs in the sink in 1/2 hour.

Actually, it's _tougher_ than mild steel or cast-iron. Less machinable.

Not a big deal, if you take steps to slow the hole-saw, and keep it
cool. Water-soluble cutting oil works great for this. It helps to have
decent-quality hole-saw, of course- bi-metal cutters. Slow it, cool it,
and put some force behind it.

What you're talking with series of drill bits sounds more like
self-torture. If you insist on making this a big-deal, you might
try to locate someone with a portable plasma-cutter.

Hi,
Ever heard of hole punch?

Local weld shop could have done it with a plasma cutter.
