ABSTRACT:
A rotary bending tool holder, particularly useful in a press brake type press, which embodies a two piece holder, namely a main body and clamp; usually attached to the moveable ram of the press brake. A rotary bending tool used with the holder is provided with elongated rectangular keyway slots along opposite sides which are aligned to received opposing tabs or keys engageable with such slots. One key is formed on the clamp of the holder while the other key is formed on the main body of the holder. Once positioned in the holder, the clamp is tightened to engage its associated key in one of the slots of the bending tool. This action causes the other key on the holder body to engage the other slot of the bending tool. At the same time opposing surfaces on the holder body and bending tool, located at the same distance from the center line of the tool holder engage to precisely align the center of the rotary head on the center line of the holder and press head.
