Abstract
A tool holder having a holder body, a collet, an intermediate rod, a clamp bolt and a pull stud. The collet and the intermediate rod are integrally connected by screwing. The collet is retracted into the holder body via the intermediate rod by rotating the clamp bolt in the first direction, and presses and holds a cutting tool. In this event, a head of the clamp bolt comes in pressure-contact with a stepped surface of the holder body by surface friction and rotates. On the other hand, in order to release the cutting tool, the clamp bolt is rotated in the second direction opposite to the first direction. In this event, the clamp bolt is rotated by rolling friction via steel balls inserted between the head and a center hole of the holder body, and the collet is pressed out forward.
