Abstract
A chuck includes a generally cylindrical body having a nose section and a tail section. A plurality of jaws are movably disposed with respect to the body to and away from the chuck's axial bore. Each jaw includes a tool engaging surface facing, and generally parallel to the axis of, the axial bore. Each jaw includes a back surface opposite the tool engaging surface and a pair of planar side surfaces extending from the tool engaging surface toward the back surface. The side surfaces are disposed on either side of a plane that includes the axis. The side surfaces define an angle through the jaw between the side surfaces that is greater than 120°.
