Half the world uses GTN 2 Clones About £50 for a box of 10.
Chronos do them of course for the Glanze parting tools, or I use Zenit GTN2 Z7. Thats a 2 mm wide one, but they come in several widths, and straight or left or right hand cutting.I get mine from DHS tools, but I can’t believe that Buck and Hickman or JML etc don’t also do them. RDG have started advertising a parting tool, and that looks very like a GTN tip in it.
I’ve seen Israeli Carbide (ISCAR) advertising them on e bay as well, selling direct.
