collet identification

[Norfolk BoyParticipant @norfolkboy]

Hi, I am having a sort out and seem to have these collets without a home. They don't appear to be Clarkson. I wonder if anyone recognises the type. They are imperial total length 1 3/4 inches.

Thanks Alan

They look very similar to the Osborn Titanic milling chuck collets, for threaded milling cutters.

Or Posilok…

They will likely fit any of the overseas Clarkson copies. As John Haine says, they are often referred to as Posilock.

See:

Also sold by RDG and under the Vertex brand.

Thank you, I did lots of searching and didn't come across them, needed that "posilock" and " Osborn Titanic milling chuck " guidance.

Fairly sure I haven't got a holder of that type so must have acquired them at some point as you do. Will go in the spares box in case…

Regards Alan
