Abstract
A chuck assembly for a rotary power tool includes a chuck body rotatable about a central axis. The chuck body has a plurality of slots, each oriented at an oblique angle relative to the central axis. The chuck assembly also includes a plurality of jaws, each movable along a respective one of the slots. The chuck assembly also includes a collar coupled to the plurality of jaws. The collar is selectively engageable with the chuck body such that, when engaged, the plurality of jaws are movable along the plurality of slots in response to rotation of the collar.

A chuck assembly for a rotary power tool, the chuck assembly comprising:
- a chuck body rotatable about a central axis, the chuck body including a plurality of slots, each of the slots oriented at an oblique angle relative to the central axis;
- a plurality of jaws, each of the jaws movable along a respective one of the slots;
- and
- a collar coupled to the plurality of jaws,
- wherein the collar is selectively engageable with the chuck body such that, when engaged, the plurality of jaws is movable along the plurality of slots in response to rotation of the collar,
- wherein the collar is movable relative to the chuck body along the central axis, without rotating the collar, when the collar is disengaged from the chuck body, and
- wherein the collar includes an external surface configured to be grasped to rotate the collar.
A chuck assembly for a rotary power tool, the chuck assembly comprising:
- a chuck body rotatable about a central axis, the chuck body including a plurality of slots, each of the slots oriented at an oblique angle relative to the central axis;
- a plurality of jaws, each of the jaws movable along a respective one of the slots;
- and
- a collar coupled to the plurality of jaws,
- wherein the collar is selectively engageable with the chuck body such that, when engaged, the plurality of jaws is movable along the plurality of slots in response to rotation of the collar,

- wherein the collar includes an external surface configured to be grasped to rotate the collar.
A chuck assembly for coupling a bit shank to a rotary power tool, the chuck assembly comprising:
- a chuck body rotatable about a central axis, the chuck body including a plurality of slots;
- a plurality of jaws, each of the jaws movable along a respective one of the slots to secure a bit shank between the jaws;
- a collar at least partially surrounding the chuck body and the jaws;
- a first plurality of threads formed on the chuck body or the plurality of jaws;
- and
- a second plurality of threads formed on the collar,
- wherein the collar is rotatable about the central axis to a first orientation to engage the second plurality of threads with the first plurality of threads and to a second orientation to disengage the second plurality of threads from the first plurality of threads, and
- wherein the collar is axially movable along the chuck body without rotating the collar when the collar is in the second orientation.
