You can drill it with the so-called cobalt bits. It drills like a hard
stainless steel (316 alloy is similar). I've only ever tried on a drill
press though, I would suspect it would be quite difficult to work with if
you only have a hand held drill.

Probably what I get for not looking up the potentials :-) Titanium is
pretty corrosion resistant on it's own in "normal" (structure/hardware/etc)
applications so I didn't think to check on it.
