摘要： An arbor including a radially expandable and contractable collet carried by a pair of axially adjustable pressure applying members. The collet is formed with spaced, inclined end surfaces, each of which is formed with a series of scallops, or undulations having smoothly curved outwardly projecting lobes joined by smoothly curved, inwardly projecting troughs or recesses. Each of the pressure applying members has a pressure applying surface engaged with one of the end surfaces of the collet, and each of the pressure applying surfaces is complementally inclined with respect to the associated end surface of the collet, and is also formed with a series of complemental scallops, whereby movement of the pressure applying members toward each other applies radial pressure to the collet and secures the collet against rotation with respect to the pressure applying members.
