Hi Dan,
You can use a 1/2" shank or 5/8" shank tool. The 5/8" will have the edge on more rigidity, or at least a better vibration damping effect.
Parting off is one of these perennial things that comes up every now and then, and for good reason. It is one of the "hard to master" processes in lathe work. Not because it is difficult, because there are different views and opinions on the subject. All right, all work, but they won't all necessarily work for you (or me).
So it comes down to finding what will work for you - another learning process
My view is to use a carbide insert tool, an insert with a positive rake, (2mm) 0.080" thick.
It must always be sharp, trying to part off with a blunt tool in the home shop using a home shop lathe is a recipe for a breakage.
I think this is all I have to say at the moment, let some others give their opinions and then you can choose which you feel is best for you
