Need to get a thread mill for live tooling 5/8 and 3/4 joint and butt tennons using a PC router with a 1/4 shaft limit? MICRO100 lists a 3/8 cutter diameter with a 1/4 shank. Is this the way to go? Kind of pricy so I would like to get it right the first time. I have dies but I dont like the results. Thanks for any feedback.

Thread mills do a very good job if you know how to program the helix'.

Wrong thread mill.

He's referring to the 4-flute live threader.

Don't skimp on this one .
Micro 100's carbide is the best in the biz.
They'll last you years and years if you take care of them.
I have a custom one that's 4" long too for the A-joint. Worth every dollar.
Have the TM-250 with a longer neck too for shaft threads and pin install.
I got it ground at farr's carbide here.

Chris Hightower sells them as well - he has two - one he prefers for interior and one for exterior. His are 1/8" shaft so they fit in a Dremel tool.

I'd do some research on live threading before deciding on a thread mill.
It's not the diameter of the tenon that counts, its the TPI that you are trying to cut. Also clearances and relief. Then go real slow.
Spinning sharp carbide tools at router speeds and engaging threading gears on a lathe should not be taken lightly. Bad things can happen really fast.
 
Ah, I see, so you are mounting a router on the tool post then cutting the threads with the lead screw. Then pitch diameter is really the only concern if the router is mounted correctly.

That type of thread mill works extremely well on CNC machines, but again, you have to know how to program the helix.
