    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: The present disclosure provides a side handle assembly for a power tool. The side handle assembly includes a clamp configured to secure the side handle assembly to the power tool, the clamp coaxially aligned with a working axis of the power tool, and a handle coupled to the clamp. The handle includes a base coupled to the clamp, a first grip portion coupled to the base, a second grip portion coupled to the base and movable relative to the first grip portion in a direction parallel to the working axis, and a damping element located between the first grip portion and the second grip portion to attenuate vibration from the power tool along the working axis.
