Abstract: An expansion tool includes a housing, a motor supported within the housing, a mandrel, and a drive mechanism configured to convert a rotational input from the motor into translational movement of the mandrel. The drive mechanism includes a cam and a drive shaft coupled to the cam. The expansion tool further includes a frame including a hub and a neck extending from the hub and having an opening. A working element is coupled to the neck and has a plurality of jaws movable from a closed position toward an expanded position in response to movement of the mandrel from a retracted position toward an extended position. The mandrel extends through the opening to engage the jaws, and the drive shaft is rotatably supported by the hub.

Abstract: A reciprocating saw includes a housing defining a motor housing portion, and a motor positioned in the motor housing portion, the motor having a motor output shaft defining a rotational axis, and a motor activation switch within the motor housing portion and adjacent the motor. The reciprocating saw also includes a transmission is positioned downstream of the motor and has a sawbar connectable to a saw blade. The transmission converts a rotational input provided by the motor shaft to a reciprocating output of the sawbar along a reciprocating axis that is either coaxial or parallel with the rotational axis.

Abstract: A handheld punch tool includes a housing defining a first axis, a motor contained within the housing, the motor having a motor shaft defining a second axis, and a head coupled to the housing and rotatable relative to the housing about a third axis. The head includes a drive member reciprocable along the third axis in response to rotation of the motor shaft about the second axis and a punch coupled to the drive member and reciprocable along a fourth axis in response to reciprocation of the drive member along the third axis. The third axis is perpendicular to the first axis, and the fourth axis is parallel to the third axis such that rotation of the head about the third axis varies a position of the punch relative to the housing.

Abstract: A hand tool for driving a fastener is provided. The hand tool includes gearing that interconnects a splined socket to a rotatable or trigger actuator and increases a rotational speed of the splined socket relative to the actuator. The hand tool may include a power tool receiver or an independent motor to drive rotation of the splined socket to advance or retract a fastener from a threaded shaft. By increasing the speed and conserving rotational inertia, the hand tool reduces the time to secure a fastener on a threaded shaft. A rotatable nut is provided. The rotatable nut can slideably orient along a first axis and threadedly orient along a second axis to fasten to an adjacent surface.

Abstract: A power tool includes a housing and a motor disposed in the housing. The motor has an axial face and a motor shaft extending from the axial face. The power tool also includes a spindle driven by the motor about an output axis, a motor plate having a central opening defining an inner surface of the motor plate, and a tolerance ring coupled to the inner surface of the motor plate. The tolerance ring has deformable waves. The motor plate is coupled to the motor by engagement of the deformable waves with the motor to take up tolerances between the motor plate and the motor.
