It's hard to believe that someone could improve on ER collet holders but the Mach-1 system pullstud does just that. Great for holding odd sized shanks and drills. Simply place the holder into the tightening fixture for a faster more convenient set up.
Combined with the Mach-1 System, ER holders have never been faster!
