The best parting tool is a bandsaw, followed by a heavily constructed lathe. Third choice is a hack saw, saw the part long & face off to length in the lathe.
A parting tool will work OK in a small lathe & the GTN is what I've used since forever. Narrower is better (say that a dozen or so times) so stay with a GTN2 (2mm or .087" wide). Specialty inserts (Iscar Do Grip, etc.) are expensive & not necessary IMHO.
Setup is critical:

Setup is critical:
- tool must be 90° to work
- tool tip must be .010" to .015" below center (.25mm to .38mm)
- Speed at least 100 sfpm
- Feed to produce a continuous chip
- Coolant helps, even oil or TapMagic
