Cutting Ti bolts
Anybody has experience in cutting Titanium bolts?
I've bought some M5 and M6 Ti bolts and will need to shorten some of them so will a hacksaw do it or it is angle grinder/dremel cut off disc
time?
Will a file or die be hard enough to reform the threads?

Use a sharp hacksaw blade and full strokes. The problem with working titanium is it work hardens so quickly, but with small bolts like that it should
be OK.

I've never done it but was under the impression it was too hard to hacksaw. Surely a small cut off wheel would be way quicker?!

hacksaws fairly easily with a fine blade, blades don't last that long though, teeth tend to fall off, and can be filed to clean threads up
afterwards

Yeah Liam, it's not as if you're 20 years of international engineering experience and studies will allow you to have any clue or offer any
helpful advice, you complete arrogant person. How dare you...

It will cut with a hacksaw no prob, and turns on a lathe with a really good finish.
Doesn't like grinding or cutting discs as these heat the edge and form Ti oxide.
This compound is hard, if fact some sanding discs are made from this.
Cheers,

p.s.
Ti swarf if coated with cutting oil or WD40 makes a spectacular display in a pub ash tray when ignited. 
p.p.s.
I probably shouldn't have said that.
p.p.p.s.
It's OK. No pub ash trays anymore.

Crap Steve dude how old do you think I am , as Paul pointed out though I clearly have very little experience working with Ti and should have kept
quiet perhaps.

I hope I haven't offended you Liam.
Very sorry if I have. Not my intention at all.
Cheers,

be careful if grinding cause even the sparks can set the filings on fire if you get a build up!

Interesting Factoid: Titanium can burn in Nitrogen.
