Abstract
A multiple collet work-piece holder having a block with a plurality of openings and a collet retainer disposed within the openings. The retainer has pistons which are subjected to hydraulic pressure for moving the collet to a clamping position. The opposite ends of the collet are completely free from any obstructions, so the work-piece can be inserted from either end, and the collet is securely held against rotation so that the work-piece can be machined as desired. Also, an automatic release of the collet is provided, so that the work-piece can be released when fluid pressure is relieved.
