Description

This collet chuck for ER-40 collets mounts on the lathe spindle in place of the lathe chuck or can be used as a fixture on a milling table.

ER-40 collet chucks range in size from 1/8" up to 1" so you can run 1" stock through the headstock of your lathe. (The through hole on the lathe spindle may be smaller.)

The outside diameter of the small collet chuck is 100 mm. It has a 72 mm registration diameter and mounts with three M8 bolts on a 84 mm bolt circle.

Chris' Tips

Chris 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.
