Double Start Taps and Dies in M10 and M12

[Curly]

I bought steel die holders along the same lines as the Delrin holder from Victor. They are cheap enough to have one for each die you use for a pen. To use one I put a transfer punch in the tailstock that fits the hollow shank of the die and offer it to the part you want to thread. Plastics can easily be threaded by hand, metals would need a mechanical advantage applied.

Great Information. I will have to do some calclating. Curly I do like that idea with individual holders. But I think I am just looking to make 2 different sizes for now.

Thanks for the responce.
