Abstract
A rotary power tool incorporates a remotely actuated chuck device. An engagement surface, such as a threaded or helical surface, is defined on an outer circumference of the chuck device over an axial length thereof. An actuator member is disposed concentric and rotatable relative to the engagement surface. In an actuation mode, the actuation member is brought into engagement with the engagement surface so that rotation of the actuator member drives the chuck device axially between gripping and release positions.
