A chuck includes a body, a plurality of jaws slidably positioned in the body, a nut coupled to the jaws so that rotational movement of the nut with respect to the body causes the jaws to move toward or away from an axial bore formed in the body, and a sleeve having a generally cylindrical inner core having an outer circumferential surface. The inner core is formed from a rigid polymer. An outer skin is adhered to the inner core outer circumferential surface. The inner core is mounted about the body in operative engagement with the nut so that rotation of the inner core with respect to the body causes the jaws to reciprocate relative to the body.
