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

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

The outside diameter of the collet chuck is 100 mm. It has a 72 mm registration diameter and mounts with three M8 bolts on a 84 mm bolt circle. The concentricity of this chuck is 0.0008" (0.02 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.
