I have aa set of collets made by Crawford that have the number 5245 stamped on them. I checked the Crawford website, google searched the number but have come up with nothing on them. They look almost like a
4C collet but are different. I'm cleaning up the shop and found them in a box on the shelf. I have no idea where they came from.tia

That will be my next step if no one here knows what they are.

Maybe this will help?

Thanks for the info.
I just looked at the thread more closely. It is a buttress thread and it looks like its 15 tpi. with a major diameter of 25 mm I think the
5245 number is the DIN number of the collet but I can't find it listed anywhere. I believe it is a metric collet for a European manufactured machine.John
Did you consider mailing Crawfords and asking?
