    Abstract: A chuck assembly includes a chuck body rotatable about an axis, a plurality of jaws each received within a slot of the chuck body for co-rotation with the chuck body about the axis, a wedge engageable with an outer surface of each jaw, a pusher coupled to the plurality of jaws to bias the plurality of jaws in a forward direction into engagement with the wedge, and a tightening sleeve threadably coupled to the chuck body for relative rotation with the chuck body. The tightening sleeve includes a clamping surface engageable with the wedge for inwardly displacing the plurality of jaws in a radial direction, causing the plurality of jaws to secure a tool bit received within the chuck assembly, in response to rotation of the tightening sleeve relative to the chuck body in a tightening direction.
