Collet identity Question
« on: May 10, 2022, 06:18:10 PM »
Hi All,
Yet another gifted items was this collet set, from 1/4in. to 5/8in. (missing 1/2in. one)
The draw bolt thread is 5/8in. UNF and overall length is about 2 3/16in.
Also included was this 5C collet
I do not have any use for these as my mill uses DA180 collets so they are available

I haven't the slightest idea, but in my bookmarks, I have this page; http://www.tools-n-gizmos.com/specs.html There are more than these out there of course, but short of going into Practical machinist, and asking there, it's a good starting point.

They look homemade.
Possibly 5C collets (without external thread) for a milling machine?
