A powered fastener driver includes a driver blade and a drive unit having an output shaft for providing torque to move the driver blade from the bottom-dead-center position toward the top-dead-center position. A rotary lifter is engageable with the driver blade and configured to receive torque from the output shaft of the drive unit in a first rotational direction for returning the driver blade from the bottom-dead-center position toward the top-dead-center position. A kickout arrangement is defined between the lifter and the output shaft and configured to permit limited movement of the lifter relative to the output shaft between a first position and a second position. The kickout arrangement having a curvilinear slot defined in the rotary lifter in which a portion of the output shaft is received.

A fastener driver includes a cylinder, a moveable piston positioned within the cylinder, and a driver blade attached to the piston and movable therewith between a top-dead-center (TDC) position and a bottom-dead-center (BDC) position. The driver blade including a body and a plurality of teeth extending therefrom. A lifter is operable to move the driver blade from the BDC position toward the TDC position. The lifter including a plurality of lugs engageable with the teeth of the driver blade when moving the driver blade from the BDC position toward the TDC position. The body of the driver blade has a first thickness and at least a first of the teeth has a second thickness that is greater than the first thickness and the first tooth has a stepped configuration relative to the body.

An oscillating power tool includes an outer housing, and an inner housing positioned within the outer housing. A motor and a drive mechanism are supported by the inner housing. The drive mechanism includes an output shaft that is rotational in an oscillating manner and that defines an output axis. A damping element is positioned between the inner housing and the outer housing through which the inner housing is mounted to the outer housing, thereby attenuating vibration transmitted to the outer housing from the inner housing.
