Using a single-row thread mill, it is possible to thread mill the larger threads
in a tight machine. If the machine has very good accuracy and no backlash,
it can do it. generally, a CNC milling machine has the accuracy for this, but
a CNC router may not. I have milled threads on my CNC milling machine,
and it worked great. I use a Micro 100 brand thread mill that I got from
MSC, and their part # is 43381262164. You may need a different size
for the 13 TPI thread.

Die? So these are external threads? That's a different program, but it
can still do it.
