When I got my second hand mill it came with some strange tooling (see pictures).
2 of the holders are expanding arbors, I've seen these on lathes for turning but these are attached to SK40 holders. Are these for shell mills or something entirely different.
Another 2 holders that I am confused about are what seems like collet holders. But when I lookt at ER collets the nut has a groove which holds the collet in place but these nuts do not have this. Does anybody know what kind of collets go in here, I can't find anything that matches up.
(Extra info: These are all SK40 holders that came with a Swiss mill, opening of the taper on the collet holder is a hair tighter than 40mm)
