I won 10 x DK20 collets on an auction site and received these, can anyone identify them please, I would like to let the seller know what he has sent.

They are 60.5mm long and the major external daimeter is 35.00mm, a 1p coin is included to give some idea of the size.

Any help would be appreciated.

Thank you

Never heard of them before, but google has plenty of hits (not just ebay) they mighht be Hardinge or 'System Erickson'

I may be wrong but I use DA 180 collets which are cross referenced I think as DK 18. Try a search for DA 200. Mine are , as Neil suggested, Erickson collets.

Could be wrong but they look like Myford one size spindle collets, if so they are tightened with a knurled ring that screws onto the spindle thread.

Hi There

I think we used these in large milling holders.

A search in some of the industrial catalogues may help.

Thank you all for the replies, I looked under Erikson and I think they are TG100's.
