Abstract: A power tool includes a housing, a motor disposed in the housing, an output spindle extending outward from the housing and configured to be rotationally driven by the motor, a keyed chuck coupled to the output spindle for rotation with the output spindle, and a chuck key holder configured to releasably retain a chuck key with a first shaft with a key disposed thereon for operating the chuck, and a second shaft coupled to the first end portion of the first shaft generally perpendicular to the first shaft, the second shaft including a lever portion. The chuck key holder includes a first recess configured to receive the first shaft and a second recess with a sheath configured to receive the second shaft with the lever portion exposed from the sheath.

Abstract: A spindle lock assembly (410, 710) for a power tool (10) includes a first rotatable part (904, 704) fixedly connected to an output member (404) of a power tool transmission (16), and a second rotatable part (426, 726) fixedly connected to the power tool output spindle (430) and operatively engaging the first rotatable part. A lock ring (908, 708) surrounds the first and second rotatable parts. The lock ring being is retained in the housing in a substantially stationary manner with a dampener (954, 754) disposed between the lock ring and the power tool housing (772) and to dampen movements of the lock ring relative to the housing in a rotational direction. The spindle lock assembly transmits rotary motion from the transmission output member to the output spindle when the rotary output member is being driven by the motor and inhibits transmittal of rotary motion from the output spindle to the transmission output member when the output spindle is driven by an external force.
