I just acquired a large lot of machine tooling... there is a set of Harding 3 piece collets with it. They are marked S20... I have 1/2, 5/8, 7/8, 1, 1 1/8, 1 1/4, 1 3/8, 1 1/2, 1 5/8, 1 3/4, 1 7/8, and one for 1 inch hex.

Looking for info on these collets... what type of chuck would they be used in? Are they worth anything?

I doubt I would ever use them for anything, so they will probably end up for sale eventually.

Thanks- Bear
