I have a nice set of small collets that I cannot match up on any of the
collet charts. Looks like a miniature R8.

Here's the specs

3.00" OA Length
.500"bearing/shaft diameter
.675 max diameter at face.
5/16-16 internal thread.
sizes 1/6 - 3/8


B3. Used on the Bridgeport "C" head, and some of the "M" heads.

The chart I have shows the back bearing to be .650" on the B3.
Mine are .500". Thread size is also different.




Another example of my typing after looking but before reading. They are
a mystery to me. Any clues from where you got them?
