A chuck () includes a jaw guide (), interleaving jaws (), and an inclined engagement surface (). The jaw guide defines a longitudinal axis () and includes jaw channels () circumferentially distributed about the axis. The jaws are slidably disposed in the jaw channels Each jaw has a clamping surface () facing the axis and a driving surface () substantially opposite the clamping surface and a protrusion () on a first lateral side and a cavity () on a second lateral side. The protrusion of each jaw is disposed at least in part in the cavity of an adjacent jaw. The engagement surface is on one of an inner surface of the jaw guide and an engagement sleeve (), and is substantially centered about the axis and substantially parallel to the driving surface. Displacement of the jaws relative to the engagement surface in a clamping direction displaces the clamping surfaces toward the axis.
