What's the trick to drilling a hole through 1/2" thick stainless
steel?
From my guardrail experience, I had bought titanium coated drill bits.
So I thought it would be easy to drill a hole in a stainless steel can
opener (for hanging on a loop outside by the BBQ cooler).
Nope!
I can't make a dent!

What's the trick to drilling through stainless steel?
Ding it with a punch to get started, else you'll just skip around on
that convex surface. Use the right cutting fluid and a slow-ish drill
speed.
And a carbide drill ! You can buy ones specifically ground for
stainless and other hard to machine materials.
