A chuck for use with a power driver having a rotatable drive spindle is provided. The chuck may comprise a plurality of jaws, a front body, a nut, a rear body, and a clutch. The clutch may be configured to move between a working position and a jaw actuating position. In the working position, the clutch teeth may be engaged with the rear body teeth such that rotation of the rear body by the drive spindle rotates the clutch, the front body, and the jaws. In the jaw actuating position, the clutch teeth may not or need not be engaged with the rear body teeth and the rear body may be configured to rotate the nut relative to the front body to move the jaws relative to the front body.

Chuck with mode control clutch

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.

Chuck with automatic jaw adjustment

A chuck for use with a power driver having a rotatable drive spindle is provided. The chuck may include a clamping assembly comprising a clamping member that operably couples the sleeve to a nut. The clamping assembly may be configured to transition the chuck between a rapid jaw adjustment mode and a clamping mode. In the rapid jaw adjustment mode, a sleeve may be configured to rotate the clamping member with the nut to cause rotational movement of the nut relative to jaws and a chuck body, which may cause translational movement of the jaws relative to the chuck body. In the clamping mode, the nut may be rotationally fixed with the jaws and the clamping member may rotate relative to the nut to cause the nut to move axially relative to a center axis of the chuck which causes the jaws to translate relative to the body and clamp onto a working bit.
