I found a box of what I now know to be threaded bits in my hangar (that were left for me by the PO). I wondered at the time what tool they would go into and found right-angle drives at Spruce, but they take 1/4-28 threaded bits.
The bits I have are 7/16-20 (or at least I think they are--see photo), but I cannot find any at that size shank anywhere let alone the tool that they would screw into.
Perplexed.
