Abstract: A chainsaw includes a housing including a handle housing portion, a motor housing portion, and a drive housing portion. The handle housing portion has a cavity extending along a longitudinal axis defining a first axis. A motor includes an output shaft having a longitudinal axis that defines a second axis. The chainsaw also includes a driven gear coupled to the output shaft, a sprocket coupled to the driven gear such that rotation of the driven gear rotates the sprocket, and a guide bar extending from the drive housing portion and having a longitudinal axis that defines a third axis of the chainsaw. The first and second axes define an included angle less than 75 degrees, the second and third axes define a second included angle between 110 degrees and 130 degrees, and the first and third axes define an external angle between 150 degrees and 170 degrees.

Abstract: A chainsaw configured to be powered by a battery pack. The chainsaw includes a housing, a guide bar, and a power and drive assembly. The housing includes a battery interface for receiving the battery pack. The guide bar guides a cutting chain and is removably coupled to the housing. The power and drive assembly includes a motor and a gear train. The motor is disposed within the housing and is configured to be powered by the battery pack. The gear train is driven by the motor and configured to drive the cutting chain. The housing, the guide bar, and the power and drive assembly each contribute to a total weight of the chainsaw. A power output by the power and drive assembly compared to the total weight defines a power-to-weight ratio of above 150 Watts per Pound.

Abstract: A tool is provided with a connector that can be configured to removably receive a corresponding connector of an extender having an antenna to electrically connect the extender to the tool. With the connector of the tool electrically connected to the connector of the extender, the controller can be configured to utilize the antenna.

Abstract: A tool system is provided that can include a tool body, a controller, and an actuator that is configured to implement a functionality. The tool system can include an extender in communication with the controller and a remote device in communication with the extender. The remote device can transmit a first signal to the extender. The extender can, in response to the first signal, transmit a second signal to the controller to cause the actuator to implement the functionality.

Abstract: A pipe threader comprises a housing and a drive assembly including a motor and an output gear having a first plurality of teeth. A die holder defines a rotational axis and includes a gear member including an outer circumference with a second plurality of teeth engaged with the output gear. The gear member includes an inner circumference with a key recess. A lock ring is rotatable relative to the gear member and including a contact surface. A key is arranged in the key recess and a biasing member in the key recess and biasing the key toward the rotational axis. The lock ring is movable between a locked position, in which the contact surface inhibits the key from moving away from the rotational axis, and an unlocked position, in which the key is movable away from the rotational axis in response to insertion of a die into the die holder.
