Think firearm components. Carbon is a no-go.

I'll preface this with I don't cut 8AL-1MO-1V Titanium (yet) lol.
Titanium Alloy 8-1-1 / 8Al-1Mo-1V - Aircraft Materials
Normally used on fan blades etc. for aircraft engine components.
Normally with something more like Ti-6Al-4v it's all about keeping the surface of the cut well below 550 degrees Celsius as that's where that material starts to play havoc with Carbide.
Normally the biggest consideration (as I'm sure you know (teaching proverbial grand mothers to such something) ) is to remove as much heat as possible from the cut.
ONLY really practical method is (for most) is high pressure TSC, like 1000 psi, and loads and loads and loads of flood coolant / overhead/ nozzle etc. [for aerospace one has to be "mindful" of introducing chlorides etc. as that can cause future surface cracking etc.].
I think the problem with your 8AL-1MO-1V Titanium is lower transition temperatures at about 450 degrees Celsius.
The makino webinar entitled
" What’s Hot and What’s Not in Titanium" (Thursday, September 22, 2011) has some useful advice on tool life and technique. [Can't link to it directly as PM "robot" doesn't like the string / url for some reason].

Most of the useful info on prioritizing stuff is about 15 mins in. Of course they want to flog a T2 machine at the same time lol. But good stuff to pull focus on though.
This webinar is kinda useful in the sense for pulling focus on priorities of things like radial engagement, chip load, axial depth of cut, surface speed etc. for GREATLY extending tool life between three and six times (from course metal removal to light roughing ) … but honestly mainly through ridiculous amounts of coolant / heat removal... even in the case of alloys like 5553 that seems to be the way.
I know that's a bit of an extrapolation on an extrapolation but I used to be professional materials scientist and seems lower heat transition temperatures and phases with 8AL-1MO-1V might cause more problems (need to verify that / phase diagrams Alpha alloy versus Beta … blah blah blah).
I can dig around... 'Cuz some of these alloys at certain tipping points compositionally can get really screwy !(sometimes do the exact opposite of what you might normally suppose) Little shaky/flakey until I/we can find better "data" and experience on that alloy.
HOVEWER seems that the peeps that make large 5 axis aerospace parts are going to be your "goto" guys on this as that alloy as I say is principally used for big jet engine fan blades and the like.

@CPM Dumb, question are you doing all milling or are these gun like components mill -turn etc. ?
I do pick up on your point about the strength of the material causing problems also.
Maybe later figure out the real difference in the alloy as lower temperature transition temperature coupled with higher strength of material may make it
worse to machine than Ti-6Al-4v (??? Like what Tomb is saying about sticking to tools etc. )… work hardening and annealing issues through heat build up + re-cutting chips. Seems TSC is pretty damn important for that.
