This 3” diameter ER-32 collet chuck mounts on the lathe spindle in place of the lathe chuck or can be used as a fixture on a milling table.

ER collet chucks range in size from 3/32" up to 13/16" so you can run 25/32" (the through hole on the lathe spindle is 0.800") stock through the headstock of your mini lathe.

The outside diameter of the lathe collet chuck is 80 mm. It has a 55 mm registration diameter and mounts with three M6 bolts on a 66 mm bolt circle. The concentricity of this chuck is 0.0002" (0.0051 mm).

*Collet must be assembled into a collet chuck nut before inserting into the collet chuck.

Chris' Tips

Chris' Tips
With all ER collet chucks, the collet must be snapped into the nut before placing it into the chuck. There is an eccentric ring inside the nut that engages the groove in the collet. That is what makes them self-ejecting. Tilt the collet again to remove it from the nut.

Here is a photo of the collet chuck mounted on a mini lathe.

Cut to the chase: We recommend the flange-mount ER collet chuck for maximum flexibility.
