Abstract
An American style press brake tool and tool holder having a safety key. The holder has a body with walls defining a downwardly open, tool receiving recess having a top, a downwardly facing force-delivering shoulder adjacent the bottom of said recess, and a shelf within said recess having an upwardly facing surface spaced upwardly from said force-delivering shoulder. The tool comprises a body having a lower work-engaging surface, an upwardly facing force-receiving shoulder engageable with the shoulder of the tool holder, and an upwardly extending tang receivable in said recess, the upper end of the tang being spaced from the top of the recess. A manually operable actuator is spaced below said force-receiving shoulder, and a safety key is coupled to the actuator for movement horizontally into and out of alignment with the shelf between locked and unlocked positions, respectively.
