The set consists of the following collets, with part numbers and sizes listed. 829041 (1/4 D), 829081 (1/8 D), 829161 (1/16 D), 829163 (3/16 D), 829165 (5/16 D), 829321 (1/32 D), 829323 (3/32 D), 829325 (5/32 D), 829327 (7/32 D) , 829329 (9/32 D) [paper tube], 829641 (1/64 D), 829643 (3/64 D), 829645 (5/64 D) [paper tube], 829647 (7/64 D), 829649 (9/64 D), 829651 (11/64 D), 829653 (13/64 D) [paper tube], 829655 (15/64 D), 829657 (17/64 D) [paper tube], 829659 (19/64 D).The collets that are in paper tubes are obviously unused as the paper is crimped over the clear window. For the plastic tubes, I have examined each collet - all collets are unused, with pristine black finish on the threads - see stereo microscope photo for an example - they have never been screwed into a draw bar. This set comes from the southwest US, and the lack of humidity and original protective oil have kept them in outstanding condition. It is extremely rare to see a complete set of these collets in new unused condition, although there are many listings for used collets that have been'polished' up a bit, improving their appearance but destroying their accuracy. In contrast, the new / unused set listed here is perfect for those who demand the highest precision from their machines.
