Abstract
A rotary power tool is provided having a remotely actuated chuck device. The chuck is mounted onto the end of a drive spindle that extends from the casing of the power tool. The chuck includes an outer sleeve member that is axially movable relative to the drive spindle between a gripping and release position. A chuck actuating device is provided having a first member engaged with the outer sleeve member and which extends generally radially outward from the drive spindle or chuck. The first member is movable in a direction so as to move the outer sleeve member between the gripping position and release position. A solenoid and a biasing mechanism engage the first member so that the chuck device is movable between the gripping and release positions.
