Abstract
A power tool having a tool portion, a chuck and a lock. The tool portion has a housing, a motor, and a spindle driven by the motor. The chuck has a body coupled to the spindle for rotation therewith, and a sleeve rotatably disposed about the body. The lock has a first lock structure pivotally coupled to the housing about a pivot axis, and a second lock structure. The first lock structure has a first locking feature. The second lock structure has a second locking feature and is coupled to the sleeve for rotation therewith. Pivoting the first lock structure into a first pivot position positions the first locking feature in a rotational path of the second locking feature. Engagement of the first and second locking features inhibits rotation of the sleeve so that rotation of the spindle will cause corresponding rotation of the body relative to the sleeve.
