Might be a tube extractor?

[bgarrett]

I should  have mentioned size.  Overall about 4.5" with a 1/4" shaft.  What kind of tube are you thinking?

sorta looks like a pulley tap?

[bgarrett]

I had to google pulley taps but No, They are not taps.  The thread is incredibly fine.   It took a while to figure out if it was a thread or merely concentric circles

[oldtools]

Maybe tapered reamers?, for wooden tapered plugs or tuning keys for Ukuleles, just uses friction to hold keys that tune the strings..

[bgarrett]

I've been wondering if these are used like a corkscrew but havent figured out which material they could screw into.

I have seen the NOT GUAR on some Mac & Snap-on tools, non-warranty items, did not come up with a match.
