|These collets came to me along with some Ames 1AM collets at the most recent Cabin Fever Auction in York, Pennsylvania.
I have no machine that these collets fit, but their threads and keyways look undamaged.
The table inserted below indicates the markings on the collets:
|In the table inserted above,
Hrdg3H means "Hardinge 3H;"
Hndy3 means Hendey No.3;" and
Hndy means "Hendey" without the "No.3."
I've arranged the sizes with the duplicates in tandem; that's why there are blanks on the table inserted above. The duplicates are the 1/2 inch, 9/16ths inch, and 11/16ths inch sizes.
As you can see from the markings, the collets were made either by Hardinge (No.3H size) or by/for Hendey (No.3 size). They all have the same thread and body size.
They are each priced at $5.00, except for the Hardinge 3H -1/2 inch collet, whose nose is worn, and the "No Size" collet, whose size has been obliterated; those are $3.00 each.
Shipping extra, at cost.
