Abstract: A rotary hammer includes a housing including a motor housing and a secondary housing. The rotary hammer includes an output device configured to provide a rotational output, an axial hammering output, or both the rotational output and the axial hammering output. The rotary hammer also includes a transmission mechanism situated within the secondary housing. The rotary hammer also includes a light holder with a plurality of light sources distributed around an output axis of the rotary hammer. The light holder includes a ring portion mounted to a front surface of the secondary housing. The light holder also includes an extending arm that extends downward and away from the ring portion in a channel of the secondary housing. The rotary hammer includes lighting power wires that are located within the channel and that are covered by the extending arm.

Abstract: A power tool assembly including a power tool and a dust extractor. The power tool includes an output chuck, a housing, a motor, and a fan. The output chuck is configured to receive a tool bit for performing a working operation and defines an output axis. The housing defines a suction inlet. The motor is disposed within the housing and defines a drive axis. The fan is rotationally driven by the motor and is configured to induce a flow of suctioning air through the suction inlet. The dust extractor is removably coupled to the power tool and includes a tool connection tube that interfaces with the suction inlet when the dust extractor is connected to the power tool. The flow of suctioning air induced by the fan flows from the dust extractor to the power tool in a direction extending parallel to the output axis.

Abstract: A rotary hammer includes a housing and a mode selection dial supported in the housing. The mode selection dial includes a cam. The housing supports a motor providing a rotational output. The housing supports a linkage moveable between a first position and a second position in response to engagement by the cam. A loss-of-control detection system measures acceleration of the housing and disables the motor upon the acceleration exceeding an acceleration threshold. The housing supports an operating mode detection system including a magnet and a Hall-effect sensor. The magnet is coupled to the linkage and moveable therewith between a third position corresponding to the first position of the linkage and a fourth position corresponding to the second position of the linkage. The Hall-effect sensor provides an output signal indictive of the position of the magnet. The loss-of-control detection system is selectively disabled based upon the output signal.
