Abstract: A battery pack that is connectable to and supportable by a power tool (e.g., a hand-held power tool). The battery pack includes a top housing having a support member. The support member of the battery pack top housing is configured or operable to reinforce a support portion of the battery pack that is used to connect the battery pack to the power tool. By reinforcing the support portion of the battery pack, an interface between the battery pack and the power tool is able to withstand greater forces (e.g., from vibrations caused by the power tool).

Abstract: The present disclosure is directed to a power tool adapted to impart axial impacts to a tool bit. The power tool includes a housing, an electric motor, and a barrel. The power tool also includes a reciprocation drive assembly coupled to the electric motor and configured to convert torque from the electric motor to reciprocating motion of a piston that is received within the barrel for reciprocation therein. The power tool further includes a striker received within the barrel for reciprocation in response to reciprocation of the piston, and an anvil received within the barrel between the striker and the tool bit. The anvil is configured to communicate axial impacts to the tool bit in response to reciprocation of the striker. The anvil defines an opening and an inner bore that communicates with the opening, and the inner bore at least partially receives a shank of the tool bit.

Abstract: A powered fastener driver includes a driver blade movable from a top-dead-center position to a bottom-dead-center position for driving a fastener into a workpiece, a drive unit for providing torque to move the driver blade toward the top-dead-center position, and a rotary lifter engageable with the driver blade. The lifter having a body and a drive pin coupled to the body. A roller is positioned on the drive pin and engages with a tooth of the driver blade when moving the driver blade from the bottom-dead-center position toward the top-dead-center position. The roller includes a first engagement section that receives an end portion of the tooth and a second engagement section. An engagement member engages the second engagement section for aligning the first engagement section of the roller with the end portion of the tooth to facilitate meshing between the end portion of the tooth and the roller.

Abstract: A power tool includes a housing, a motor positioned substantially within the housing, a drive mechanism supported by the housing and coupled to the motor, a battery pack electrically coupled to the motor, and an isolation system. The isolation system includes an interface member positioned substantially within the housing. The interface member receives a portion of the battery pack to electrically couple the battery pack to the motor. The isolation system also includes a plurality of isolators coupled between the housing and the interface member to isolate the battery pack from the housing during operation of the power tool.

Abstract: A fastener driver includes a housing having a handle portion. A motor is positioned within the housing. The fastener driver further includes an air compressor including a compressor cylinder and a compressor piston movable within the compressor cylinder in a reciprocating manner to compress air within the compressor cylinder. The fastener driver further includes a drive train converting torque from the motor to a linear force applied to the compressor piston, causing the compressor piston to move in the reciprocating manner. At least a portion of the drive train extends through the handle portion of the housing.

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.
