Single Taper Collets		• Ideal for chucking on O.D. or I.D. of part • Allows for chucking on narrower chucking lands • Does not accommodate tapered chucking surfaces • Split from one end or split from both ends • Part does not have to be inside entire chucking land • Can be threaded on one end to attach to piston or draw bar

Double Taper Collets		• Ideal for chucking O.D. or I.D. of part in two places • Allows for chucking on tapered parts or where the bore is not perfectly straight • Split from each end allowing for opposite sides to be independent of each other • Extra rigidity by chucking on two locations of a part

Features		• Holds internal diameters of part when outside diameter cannot be held • Used to hold outer diameters as needed • Part stops designed for repeatability: Air Sensing available to determine if part is loaded correctly • Repeatability < .0002 • Collets Preloaded: Anti-rotate incorporated so collet does not spin
