    Thanks for the comments guys! I really do appreciate them. As I said, it was just another challenge for me and it worked! It was set up in a steady and actually the first time using a steady rest, so it was a two time learning experience...

    Thought you might like to see some threads cut by a professional cnc shop for comparison. :)

    I needed 50 parts for work and nobody, including me, wanted me to spend my time making them on manual machines so my boss contracted them out. This is what we got.

    Hey...for our purposes they will work so despite the appearance, we're using them. Especially since we had them made and our customer cancelled the order (we said no, we're not eating these). Ah the joys of business these days...

    Those look thread-milled.

    Maybe so, is that typical appearance for milled threads?
    Reminds me of needle thrust bearings.

    If you have not tried threading in reverse away from the chuck you are missing out. You can actually use the threading tool to cut the relief and thread out from there. It is less stress and you can use higher spindle speed (300 rpm works well).

    Here ia what I ended up with. It is a LH tool mounted upside down.

    ^^^ just be sure you do not do this if you have a threaded spindle. Otherwise its a good method

    I milled threads on thousands of parts. Those don't look milled to me.

    Thanks guys! I took my time today and hit all the numbers perfect. Can't say enough about the AR Warner hss threading tool! Cuts were clean and sharp with no ragged edge. Game changer!

    Those AR Warner threading tools are a little spendy (around $100). The Shars threading tool I use costs just $32.00 plus $9.30 for the insert. I have always been satisfied with Shars tools.

    I use the AR threading bar, but use carbide inserts with top rake on them. I use them simply for longevity. The HSS looses the edge a bit too quick for the $$$

    For some reason I’ve never been happy with Warner inserts. Never could get a nice finish or a nice thread. My hand ground tools worked better for me. But Carmex laydown inserts have been great.

    Lol! I don’t think I have enough years left to learn how to do that!
