Abstract: A power tool includes a housing, a motor supported by the housing, and an output spindle rotatably supported relative to the housing about an axis. The motor is operable to drive the output spindle about the axis. The power tool includes a spindle lock assembly between the motor and the output spindle. The spindle lock assembly is adjustable between an unlocked state in which the output spindle is rotatable relative to the housing about the axis and a locked state in which the output spindle is rotationally fixed relative to the housing. The spindle lock assembly includes a first resilient member, positioned between the housing and the output spindle. The first resilient member is configured to at least partially absorb a torque impulse from the output spindle when rotating in a first direction and when the spindle lock assembly transitions from the unlocked state to the locked state.

Abstract: A power tool is supportable by a lanyard. The power tool includes a motor housing, a motor arranged in the motor housing, front housing, an output member extending from the front housing, a gear case, and a gear train arranged in the gear case. The gear train is configured to transfer torque from the motor to the output member. The power tool also includes a first fastener securing the front housing to the motor housing, and a bracket fastened to one of the front housing, the motor housing, or the gear case by a second fastener that does not secure the front housing to the motor housing. The power tool also includes a support member secured to the one of the front housing, the motor housing, or the gear case by the bracket. The support member is attachable to the lanyard.

Abstract: A power tool may include a compartment in its housing and a first printed circuit board (PCB) located in the housing and electrically coupled to a first connector. An insertable wireless communication device may include a second electronic processor and an antenna that are each mounted to a second PCB. The insertable wireless communication device may be configured to be received in the compartment and may include a second connector configured to electrically and physically couple to the first connector. The insertable wireless communication device may be configured to wirelessly communicate with an external device. When the insertable wireless communication device is inserted into the compartment, a first conductive layer of the first PCB may be configured to be electrically coupled to the antenna via the first connector and the second connector such that the first conductive layer of the first PCB serves as a ground plane of the antenna.

Abstract: A rotary impact tool includes a housing, an electric motor, and a drive assembly for converting a continuous torque input from the motor to consecutive rotational impacts upon a workpiece of at least 900 ft-lbs of fastening torque. An anvil has a bore defining a hexagonal cross-sectional shape and having a nominal width of 7/16 inches. A hammer is rotationally and axially movable relative to the anvil for imparting the consecutive rotational impacts upon the anvil. A spring biases the hammer in an axial direction toward the anvil. A battery pack has a nominal voltage of at least 18 Volts and a nominal capacity of at least 5 Ah. The rotary impact tool has an overall weight including the battery pack that is less than or equal to 7.5 pounds. A ratio of the fastening torque to the overall weight is greater than or equal to 120 ft-lbs per pound.

Abstract: A power tool including a housing, an input, a gear train, a motor at least partially supported by the housing and coupled to the gear train, and a controller including a processor and a memory. The controller is coupled to the input and the motor and is configured to receive an input signal from the input, determine an operating direction and an operating speed based on the input signal, cause the motor to rotate the gear train in a direction opposite the operating direction for a predetermined amount of rotation, and cause the motor to rotate in the operating direction at the operating speed.
