Abstract
A press brake tool and tool holder. The tool has a body terminating downwardly in a workpiece-engaging surface and a tang extending upwardly from the body and adapted for reception in a tool holder, the tang having a first wall defining a vertical surface and a second wall on the opposite side of the tang having a recess formed therein having a contact surface. The tool holder has an opening therein for reception of the tool tang, a vertical surface engagable with the vertical surface of the tang, and a clamping pin movable transversely of the opening for clamping the tool in the holder. The pin has a camming surface configured to engage the contact surface of the tang in line contact to exert a force on the tang having vertical and horizontal components, the ratio of the vertical component to the horizontal component desirably changing as the clamping pin clamps against the contact surface of the tang.
