Patent ID: 7021116

Claim:
A press brake tool that is adapted for being mounted in a tool holder by moving the tool vertically into a channel defined by the tool holder, wherein the tool is adapted for being dismounted from the tool holder by moving the tool horizontally out of the channel, and wherein the tool is not adapted for being dismounted from the tool holder by moving the tool vertically out of the channel, the tool having a shank that is provided with a safety key, wherein the safety key is biased toward an extended position when the shank is moved to an operative position in the channel of the tool holder, and wherein the tool has no externally accessible actuator for retracting the safety key such that once the tool's shank is moved into its operative position in the channel of the tool holder a press brake operator is prevented from retracting the safety key and removing the tool vertically from the tool holder, wherein the tool has a leading body portion that terminates at a tip, the leading body portion being that portion of the tool that is not concealed by the tool holder when the shank is in its operative position in the channel of the tool holder, wherein the leading body portion of the tool is defined entirely by solid wall having no openings, wherein the tool includes a spring member that biases the safety key toward said extended position, wherein the safety key defines a flat that is adapted to slide along a planar surface of the tool holder when the tool is dismounted from the tool holder by moving the tool horizontally out of the channel, wherein the flat reduces gouging of said planar surface resulting from such sliding.
