Oh yeah. Any HSS drills will, but there is benefit in using some of the harder alloy drills if you have them. Slow speeds and lots of coolant regardless. Ti is similar to some of the marine-grade stainless steels when it comes to working it. A bit tougher and still less heat transfer, but similar overall. But drilling and pinning isn't on my list. There's a lot that could be done. I'm thinking material buildup, re-boring, groove cutting, and heat expansion for attachment. Brazing is also an option, but seems complex for Ti to Al. I've never done that, but I may try.
