Thanks for the info Griff. How have the end mills held up? How about the coatings, are they durable? It’s hard to believe they are US made at those prices. Their Ebay account has 100% positive feedback though which says a lot.
Thanks @Griff. They look almost too good to be true. Nice prices (especially on the thread mills) and free shipping in the US.
Maybe you guys can answer this sort of related question:
I’m interested in getting a thread mill as well, but feel like I have much to learn on that topic. From what I know, if I wanted to use my SO3 to make 1/4-20 threaded holes, would I buy something like this mill from the Rogue Systems site. That gives me the 20 TPI required, but would that be too big for a 1/4" hole (which is really .257" to .266" diameter depending on your fit tolerance)? Fusion 360 has a thread milling toolpath, but I haven’t tried it.
Edit: Seems like it would work in theory at it is a 3/16" shank, with a .180 cutting diameter. Provided I can use the correct settings in Fusion…

I’ll be watching for your experience here. My setup is all apart (again ) so I can add an enclosure.
