V-Mar 3J Collet Stop Extensions

Screw these into the back of your 3J collets, then screw your collet stop into the back of the extension. This allows you to setup a positive work stop for longer parts.

The collet and collet stop shown in the photo are NOT included. The photo with the collet is just to demonstrate how the extensions are used. We sell the collet stop separately, check it out here.

The extensions come in 3", 6" or 12" lengths but you can screw them together to get even more length.

Made in the USA from 6061 aluminum.

We recommend using spindle sleeves to support the extensions for the 12" and longer (stacking them together for more length) especially if you are turning at a higher spindle RPM. Just like you would for long bar stock.

The OD of the extensions is 1.910", the ID measures 1.610"
