Abstract: A reciprocating saw includes a blade assembly having a spindle and a blade clamp. The blade clamp includes a cover rotatably coupled to the spindle, and a detent movable in a radial direction to adjust the blade clamp between a locked configuration and an unlocked configuration. The cover is rotatable between a first rotational position relative to the spindle coinciding with the locked configuration, and a second rotational position relative to the spindle coinciding with the unlocked configuration. The reciprocating saw further includes a barrel surrounding at least a portion of the blade clamp. The barrel includes a plurality of projections extending from the barrel toward the blade clamp. At least one of the projections is engageable with the cover to rotate the cover from the second rotational position to the first rotational position, thereby adjusting the blade clamp from the unlocked configuration toward the locked configuration.

Abstract: A reciprocating saw includes a housing, a motor, a drive mechanism, and a support assembly. The drive mechanism includes a driven gear, a connecting rod, and a spindle. A first end of the connecting rod is moveably coupled to the spindle by a roller pin. Rotary motion of the motor is translated into linear reciprocating motion of the spindle by the driven gear and the connecting rod. The support assembly rotationally supports the roller pin and includes a housing which defines a slot. A first bearing is positioned within the slot at a first end of the roller pin, and a second bearing is positioned within the slot at a second end of the roller pin. At least one of the first end and the second end of the roller pin extends completely though the first bearing and the second bearing, respectively.

Abstract: A rotary hammer adapted to impart axial impacts to a tool bit. The rotary hammer includes a housing, a motor supported by the housing, a spindle coupled to the motor for receiving torque from the motor, causing the spindle to rotate, a reciprocation mechanism operable to create a variable pressure air spring within the spindle, an anvil received within the spindle for reciprocation in response to the pressure of the air spring, the anvil imparting axial impacts to the tool bit, a bit retention assembly for securing the tool bit to the spindle, and an electromagnetic clutch mechanism switchable between a first state, in which the reciprocation mechanism is enabled, such that the anvil imparts axial impacts to the tool bit, and a second state, in which the reciprocation mechanism is disabled, such that the anvil ceases to impart axial impacts to the tool bit.

Abstract: A powered fastener driver includes a driver blade movable from a top-dead-center (TDC) position to a bottom-dead-center (BDC) position for driving a fastener into a workpiece and a drive unit for providing torque to move the driver blade from the BDC position toward the TDC position. A kickout arrangement is at least partially defined by an outer surface on one of a torque output member and a torque input member and an aperture formed in the other of the torque output member and the torque input member in which the outer surface is received. The kickout arrangement configured to permit limited rotation of the torque output member relative to the torque input member between a first position and a second position.

Abstract: A rotary hammer includes a motor and a spindle coupled to the motor for receiving torque from the motor. The spindle has an adjustable rotation speed. A reciprocation mechanism is operable to create a variable pressure air spring within the spindle and includes a piston configured to reciprocate within the spindle in response to receiving torque from the motor. The piston has an adjustable reciprocation frequency. A striker is selectively reciprocable within the spindle in response to reciprocation of the piston. A first transmission is transfers torque from the motor to the spindle and a second transmission is transfers torque from the motor to the reciprocation mechanism. The reciprocation frequency of the piston is adjustable independent of the rotation speed of the spindle. The rotation speed of the spindle is adjustable independent of the reciprocation frequency of the piston. At least one of the transmissions is a multi-speed transmission.
