So, I've run into issues having to wait a day or two to get tooling for some job shop work that comes through (I 99% support my in house product line, but also do some other stuff on the side) or other dumb projects. I've only been machining for a few years now so my tool crib is pretty sparse other than the specific tools for my products. I'm considering getting a few common thread mill sizes so I can tackle wide ranges of thread sizes and pitches (including metric, hopefully) in random materials, as it looks to be more economical than stocking a cabinet full of taps for one-offs and really short runs in multiple styles.
1) Are ISO and UN thread forms the same, or functionally close enough for use when there is no specification ("must accept 1/4x24 cap screw," for instance) called, or when I'm making in-house tooling or fixtures?
2) If I get a small variety of single point thread mills, can I cover myself for a wide range of ISO and UN threads?
3) What am I not considering?
