Abstract
The present invention is a tool holder for receiving an endmill or similar tool. The tool holder includes a shank portion adapted to fit into the spindle of a machine, and a closed end collet integrally formed with the shank portion. The collet includes an axial bore for receiving the tool and a plurality of resilient collet segments for gripping the tool. The collet segments are separated by a plurality of axially extending slots which terminate inwardly from the forward end of a collet. A continuous tie ring extends around the forward end of a collet and joins the plurality of collet segments together. The continuous tie ring provides for increased radial stiffness at the forward end of the collet which improves accuracy and repeatability of tool location. A lock nut threads onto the collet to collapse the collet segments radially inwardly to grip the tool.
