What is the best way to shorten a ti bolt by 2-3mm?

Does it work well with grinder or sander? I would think Ti is a little softer than steel sonit should go quickly

I've always used a dremel for that. works perfectly. make sure to clamp the bolts in some wood in a vice. they get hot!

Bench grinder. Dip in water frequently to cool.

I'd agree with bench grinder. If you happen to have an old nut that matches the threads, put it on before hand. When you're done grinding, unscrew the nut off the end and that will help correct the cut threads at the end of the bolt.

I never remember to put a nut on first, so I usually grind the corners off the threads at roughly a 45 degree angle. That gets most of the burrs and deformed threads.

Well ideally a lathe and thread file or die. That would get you a perfect result... But dremels work too

I use a combination of spacers / washers with a nut on the end to get the desired length of thread.
I then use a dremel with cutoff disk to shorten the bolt and then file down any sharp threads left on the end.
