Abstract
Various chucks for use with a power driver having a rotatable drive spindle are provided. One chuck includes a plurality of jaws disposed at a forward end of the chuck, a body, a push plate, a jaw spring, and a nut. The plurality of jaws may be disposed in the body and configured to rotate with the body about a center axis of the chuck. The push plate may be operably coupled to each of the jaws. The jaws may be configured to translate forward to close the jaw opening in response to the push plate translating axially forward. The jaw spring may be configured to apply a forward directed force to urge the push plate forward. The nut may have nut teeth that cause the jaws to translate forward and clamp onto the working bit in response to the nut being rotated in a tightening direction.
