Trying to ID some old collets
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. http://members.aol.com/gto69ra4/photos/collets.jpg Anyone? GTO(John) |

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.

Those look like screw machine collets, not much use in a home shop lathe. I
had some that were similier and ended up dumping them, no ebay buyers. I had worked at Amphenol in the past and one of the old machine operators said they used collets like that 40 years ago, most were made in house. "GTO69RA4" wrote in message ...

In article ,

You may be able to ID them from one of the docs he http://www.hardingeworkholding.com/w1collets.html I just quickly scanned the Hardinge workholding catalog and the first match I see is for a Hardinge no. MP1287 which fits a Pratt & Whitney #2 turret lathe. Ned Simmons |

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. Brian Lawson, Bothwell, Ontario.

I'll have to look at the markings and see if there are any old letter or wire sizes stamped on em.
