I bought two of these "things" at a market a while ago, not knowing what they were, and I still don't know.
I am very curious.

Each is threaded 1/2 inch 20 TPI male and female at each end, as in photo.
The units come apart and are held together with a ball retainer.
There is a magnet inside each end to retain something.
No other markings than as in photo.
Very well made.
Unused.

I thought that they may be some kind of quick change drill chuck attachment, seeing as the threads are 1/2 x 20.

Free to anyone in Brisbane who wants them and can pickup, and who has posted more than 10 times in this forum.
I will wait ten days to see who is "in the hat" and then select the lucky new owner.
