I have several of this type of small collet and have often wondered what they fit. Does anyone have any idea?>>

Overall length is 5/8" and the two diameters at the nose end are 17/32" and 27/64". The diameter at the back end is 11/32".>>

The box they came in contained - amongst other bits - a half finished brass clock face but of course that could be a red herring!>>

They look a bit like the collets we used in right angled windy drills - Desouter ??

I think they are made for the Taig lathe (can't remember what the brand is called over here. I bought a headstock for a dividing head project years ago (based I think on a Tony Jeffree design) with a set - they aren't very well finished are they!

Afternoon Martin, nice to chat albeit briefly. John, I have checked and it looks like you are right in suggesting TAIG. Having looked at their collets I seem to have the full set of seven.

I agree, the one pictured does look a bit rough but my camera is very good at enhancing imperfections. Its not as bad as the picture shows. Good work chap and thank you!

Clare collets were specifically for Clare milling cutters. They were unthreaded in the area where Clarkson cutters are, but they had a special tongue instead. The idea was that you inserted the cutter into an appropriately-sized collet, twisted it a few degrees to engage the tongue with the collet and then tightened the closing nut.

You can sometimes get Clare collets second-hand, but otherwise the collets are pretty well useless. They'll probably grip a Clarkson or plain cutter reasonably well, but the grip won't guarantee it being pulled out.

We used them back in the 1970s in the apprentice school!
