Abstract
A clamping device used for securing a toolholder for metal working operations includes a lock rod reciprocating along a lock rod longitudinal axis to radially activate locking balls to engage perforations within the shank of a toolholder, wherein the toolholder is oriented along a toolholder axis non parallel to the locking rod longitudinal axis. Additionally, the lock rod includes a ramp which engages a bump-off pin in a direction lateral to the motion of the lock rod to provide a mechanism for ejecting the toolholder from the clamping device.
