The back side of the nut tool

The magic of this tool is the two metal plates that ride in the track that establishes the pitch for the treads.  There is a scraper blade that sticks out of the tool that you advance, inching it up as you cut the internal threads deeper.  To make an internal set of threads takes roughly 50 or so passes of the cutter.  Goes faster at the start, but once you get most of the thread profile you need to go slower because you can only remove so much material in a pass or it will clog up.

Update: After a number of nuts I finally broke my cutter; it was a metal lathe “cut off blade” shaped with a grinder to the thread profile.  It will be a simple matter to make another one.
