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!

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.
