Looking forward to the rest of this series! Triform is totally new to me, for one thing.

Using a relatively full-form threadmill and you can thread a hole faster than a tap, especially at bigger sizes. Though one of the downsides at that scale is the expense. I got a threadmill to do 1/2-13 holes in steel and it will do them in a couple seconds each, vs having to peck tap or go slowly with a bigger tap like that, and the biggest downside is that it's a $130 tool.

I agree with most everything you said about the advantages of thread milling. Great info, but given in such a generic format you left out some of the other disadvantages. Like the absolute need for a tread gage if thread milling (yes you could use a bolt, but how do you know if the bolt you fit it to is at high or low limit for the bolt tolerance). Thread milling super deep holes is also a huge PITA compared to tapping. Taps cost about 75% less than a thread mill in a 1 to 1 comparison as well, assuming your not buying the cheapest crap available.

If you are making a lot of holes a Go-No go gage is the way to go. They are costly but help quickly identify the quality of the dimensions. Great comments. Appreciate you and thanks for watching.
