Thread milling, can anyone help

[CAMmando]

I do it in MasterCAM so I would not really have interest in a stand alone program for that specific task.

Onecnc and Bobcad also have a helix function, perhaps most CADCAMS already do this, plus quite a few tool companies provide little (free) applications to generate cycles for their thread mills. I tell you this just so you could decide if you thought it was worth your while to create another

Any place to mail order these at a reasonable price. The local guy is quoting me $160 for the SCT cutters. That seems outrageous.

That price is not bad, not sure why they are so expensive but they are.
Try page 334 & 335 of the MSC catalog:

Hmm...

Has anyone tired creating a threadmill?

I was thinking that something that held lathe tools, like a fly-cutter, but at 90 degrees . Wouldn't be able to bottom out, but a heck of a lot cheaper.

I think I would cry if I broke a $160 cutter that I paid for myself.
