I have a Taig Micro Lathe and am attempting to make a few small nozzles for one of my projects out of 6mm 304 stainless threaded rod.
I need to put a 5/64 bit 1-3/4" deep concentrically but I have not even managed to create a single bloody chip! I have tried many speeds and feeds with both HSS and Titanium 135deg drill bits but not a single one will bite. I also tried a #3 center drill and that went in a tiny bit but then much have work hardened the rod.
I live in canada and only have the box stores nearby, I can order bits online but will need a place with reasonable shipping.
Does anybody know how the heck I can accomplish this? I need to make 10 of these things...
