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.

Abstract: A handheld power tool including a housing, a tool receptacle disposed on a first end of the housing and configured to receive a tool accessory, and a motor positioned within the housing and operatively coupled to the tool receptacle to drive the tool accessory. A dust container is selectively coupled to the housing. A dust tube is coupled to the first end of the housing and in fluid communication with the dust container, wherein the dust tube is movable between an extended position and a retracted position. A fan is positioned within the housing and is operable to generate a suction air flow path through the dust tube and into the dust container, wherein the fan rotatably driven by the motor.

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.

Abstract: The present invention provides, in one aspect, a router including a motor unit and a base configured to selectively receive the motor unit to support the router on a work piece surface. The motor unit includes a motor and a spindle configured to output a torque supplied by the motor. The base includes an input shaft configured to selectively couple to the spindle, an output shaft laterally offset from the input shaft, and a belt. The input shaft includes a first pulley and the output shaft includes a second pulley and a tool holder. The belt wraps around the first and second pulleys to rotationally couple the input shaft to the output shaft. When the motor unit is received into the base, the spindle couples to the input shaft.

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, a first motor supported by the housing and defining a first motor axis, a second motor supported by the housing and defining a second motor axis that is coaxial with the first motor axis, and a spindle coupled to the first motor for receiving torque from the first motor, causing the spindle to rotate. The rotary hammer further includes a reciprocation mechanism operable to create a variable pressure air spring within the spindle. The reciprocation mechanism includes a piston configured to reciprocate within the spindle in response to receiving torque from the second motor, a striker that is selectively reciprocable within the spindle in response to reciprocation of the piston, and an anvil that is impacted by the striker when the striker reciprocates towards the tool bit. The anvil imparts axial impacts to the tool bit.

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.
