Yes, I have fine cut tips for the X45 hand and machine torch. They are rated at 15 to 30 amps with an orifice hole of 0.8mm/.030". These cutting tips use a different CNC shield as they are shorter then the 45/50 amp tips and testing has shown that a .050" torch height works well, but may vary from setup to setup. At this time I am also working on a un-shielded fine cit setup that may work very well on thin metal.
Consumables for the X45 torch are listed here.
