Abstract: A gas spring-powered 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 driven or bottom-dead-center (BDC) position. The driver blade includes a body and a plurality of teeth extending therefrom. The driver blade defines a driving axis. The gas spring-powered fastener driver further includes a lifter operable to move the driver blade from the BDC position toward the TDC position. Each one of the plurality of teeth includes a contact surface engageable with the lifter. The contact surface of each tooth defines an included angle with the driving axis that is greater than 90 degrees.

Abstract: A gas spring-powered fastener driver includes a cylinder, a moveable piston, a driver blade attached to the piston, the driver blade movable with the piston, a lifter including a rotary component operably coupled to the driver blade to move the driver blade from a driven position to a ready position, and a multi-stage planetary transmission. The transmission includes an output shaft operatively coupled to the lifter to provide torque thereto, a first bearing supporting a first portion of the output shaft for rotation, a second bearing supporting a second portion of the output shaft for rotation. The fastener driver also includes a housing having a cylinder support portion in which the cylinder is received and a transmission housing portion in which the first and second bearings are received to rotatably support the output shaft. The cylinder support portion and the transmission housing portion are integrally formed as a single piece.

Abstract: A powered fastener driver includes a magazine in which fasteners of a first length or fasteners of a second length greater than the first length are receivable. The magazine includes a shear block located at a first end of the magazine, a loading portion located at a second end of the magazine, and a feed channel extending lengthwise through the magazine between. The loading portion of the magazine includes first and second slots configured to receive fasteners of the corresponding first and second lengths for entry into the feed channel, and a feed channel access gate configured to prevent fasteners of the first length from being loaded into the second slot. The feed channel access gate is configured as a pivot member pivotable about an axis between a first, blocking position, and a second, bypass position. A spring biases the feed channel access gate toward the blocking position.

Abstract: A gas spring-powered fastener driver includes a cylinder, a moveable piston positioned within the cylinder, a driver blade attached to the piston and movable therewith between a ready position and a driven position, a lifter to move the driver blade from the driven position to the ready position, and a transmission including an output shaft operatively coupled to the lifter to provide torque to the lifter. The fastener driver also includes an input to provide torque to the transmission and a clutch positioned downstream of the input and operably coupled to the output shaft to limit an amount of torque transferred to the output shaft and the lifter. In response to an application of a reaction torque to the output shaft above a predetermined threshold, torque from the input is diverted from the output shaft via the clutch.

Abstract: A power tool includes a housing having a base configured to support the power tool relative to a workpiece. The power tool includes a handle coupled to the housing. The handle defines a longitudinal axis and includes a first portion positioned between the longitudinal axis and the base and a second portion opposite the first portion along the longitudinal axis. The power tool includes an activation switch coupled to a side surface of the housing. The activation switch is slidable in a direction parallel with a switch axis that intersects the longitudinal axis from a deactivated state, in which the drive system is non-operable, to an activated state, in which the drive system is operable. The activation switch is slidable toward the second portion of the handle from an intersection point between the switch axis and the longitudinal axis.

Abstract: A rotary hammer includes a motor, a spindle coupled to the motor for receiving torque from the motor, a piston at least partially received within the spindle for reciprocation therein, a striker received within the spindle for reciprocation in response to reciprocation of the piston, and an anvil received within the spindle and positioned between the striker and a tool bit. The anvil imparts axial impacts to the tool bit in response to reciprocation of the striker. The rotary hammer also includes a synchronizing assembly operable in a first configuration in which the motor is drivably coupled to the piston for reciprocating the piston, and a second configuration in which the piston is decoupled from the motor. The rotary hammer further includes an actuator operable for switching the synchronizing assembly from the second configuration to the first configuration in response to depressing the tool bit against a workpiece.

Abstract: A rotary power tool includes a housing, a spindle defining a working axis, and a motor supported by the housing. The motor is operable to drive the spindle. The rotary power tool also includes a handle movably coupled to the housing and a vibration isolating assembly disposed between the housing and the handle. The vibration isolating assembly attenuates vibration transmitted from the housing to the handle. A battery pack is removably coupled directly to the handle and configured to provide power to the motor.
