I wonder if it is a holder for a die that is being used as a thread chaser on long full thread rods for I can't imagine that anyone could successfully cut a good thread on plain bar/rod with an unequal pressure on the diestock /holder . Another thought I just had is that perhaps the die & stock holder are held rigidly in a clamp and the almost finely finished rod is turned through the die using a drill or lathe of some kind , that might result in a fairly good thread on certain metals.
Interesting that one side has been turned to a true circular boss , thinking cap back on ?
I also think that the fact that I found the holder with a male threading die in it doesn't necessarily mean that the part was intended that way....
Have a wonderful weekend all,
Carsten
