Hello,

Does anyone know what these collets fit? I picked them up in a tooling lot and I would like to resell them but I don't even know what they are.

My one clue is that the same lot included a set of Pratt & Whitney 5p collets, and there is an adapter to use them with the 5p draw bar. So I think they fit some kind of collet chuck that was used with a Pratt & Whitney lathe.

The sizes range from 1" to 1 5/8" in 1/8s.

Body diameter = 1.75"
Head diameter = 2.0"
Body length = 2.15"
Total Length = 3.4"
Stem (?) diameter = 1.22"
Thread = 1/2-13
