Here are some collets I'm trying to ID. 2 5/8" LOA, 15/16" wide around the machined area at the base. No threads. I have a whole board of these, in all different round and hex sizes, plus a few odd ones like rectangular holes.

Probably WW-II vintage collets for Logan's proprietary production closer, which was mounted ahead of the spindle and did not utilize a drawtube.
As long as someone else is asking about collets.....
I have about 150 that I haven't been able to I.D. either. They're about .565 dia x 1.25 long with no thread for a draw tube. profile is similar to what GTO posted except nose isn't tapered and they are smaller
Also in the same box, .75 O.D. x .1.5 long and many .375 O.D. x 1.25 long (these have a tapered nose)
Yea, it's a little hard without posting a pic but I was hoping someone might at least know what to look into so I could try and ID them myself.
Or...if you can use em, let me know. I'm kinda tired of tripping over them. I'll give better details and send a pic.

Brown and Sharp Dead Length collets. They go into a holder that clamps the collets without changing the length. This is an older type Ive only seen a couple times before.
YMMV

Hey Koz,
Hmmmmm.....without going out to the shop to measure, these might be the collets used on a drill sharpener. They would chuck into a holder collet on the machine, one collet for each size drill but. Mine has from 1/16 to 1/2 by 64ths, plus A to Z letter, plus 1 to 59 Number. They have the drill size stamped on the face of each.
Take care.

Now that makes sense..there are a ton of sizes that tend to be in the wire range. I'll have to look at the markings and see if there are any old letter or wire sizes stamped on em.
