New, NEVER USED Travers thread mill. Solid carbide by Micro-Tool.

1/4" dia, 4 flute with .100" x 1.000" neck x 2.5" OA length.

The neck would have to be lengthened for 3/8-10 or 11 shaft work but it can be used as-is for JPs, ferrule tenons, ferrules, joints & joint collars. Can also be used to live tool for brass inserts in shafts.

Price is SOLD.

I acquired one a while back with the neck already lengthened. I got another last week, any recommendations on lengthening a solid carbide thread mill shank?

The proper method is to have it ground with a diamond wheel. Any competent machine shop can do it in 15 minutes. Note: you only need it lengthened if you're using it to cut internal 3/8 shaft threads. Virtually every other application can be done with the std neck.

And, due to the .382 bore that locates a modified pin in the butt, even those 3/8-10 threads can be machined with a std neck, however, you need a 3" long thread mill to get 2 1/4" depth while still having something substantial to grip in your router (plus a little breathing room).

This video shows how to cut the bore, counter bore and threads in a ferrule using CNC. Much easier than live tooling in a lathe & infinitely more accurate than your typical vendor supplied ferrules.

IMO, live tooling is the best way to threads any of the linen-based phenolic or epoxy composites. The set of 3 shown below handle everything I need to thread on a cue.
