The ONLY Customizable Machinable  Expanding Mandrel How To Buy
6000 Series - expanding mandrel New Speed-Stix

Introducing the newest member of the

Xpandrel Product Family


Affordable quick solution for your standard precision parts.

 

This expanding mandrel has only 1 actuation point, not as dimensionally stable as having 2 of more expanding locations, however suitable for most short parts.
