Help identifying collets for BT30 Meccanica Cortini L300 C3

Hi

Can you help for found what is this collet ? I have several off this for each size but only one tool holder

I have try BT30 er25, the tool holder is ok but the collet not compliant.

This is for old mill Meccanica Cortini L300 C3

Hi
you may not be lucky with the TRY
get you from the ebay a new set from Mashineshop returns
clamp and collet system are somehow for less then 30USD


the new system BT30 is a hell of a mess as every toolmaker only does use the cone but makes its own clamp system

in image it looks like a more SK40 collet to ER25 as of the length

probably DIN6388 (OZ16) but i'm not sure

Thanks you two for answear.

I think you are right this is possible to be OZ16 or EOC16 but found BT30 OZ16 seem to be not easy.

@bbsr_5a : Maybee you are right and the best option is order a full set BT30 ER25 or 32

Thanks a lot
