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.

Abstract: A power tool includes a motor housing, a motor, a handle coupled to the housing, and a vibration damping assembly. The motor is positioned in the motor housing and configured to rotatably drive an output shaft. The vibration damping assembly is positioned between the motor housing and the handle. The vibration damping assembly includes a first coupling portion defined by the motor housing, a second coupling portion defined by the handle, and an elastomeric damper captured between the first coupling portion and the second coupling portion. The first coupling portion includes a boss having a flange and a first groove. The second coupling portion defines an opening and includes first and second ribs extending into the opening and spaced apart along a longitudinal axis of the handle. The first and second ribs define a second groove therebetween. The damper occupies the first and second grooves.

Abstract: A bit retainer is configured to couple a tool bit to an output spindle of a power tool. The bit retainer includes a body coupled for co-rotation with the output spindle about a rotational axis, a collet including a plurality of jaws positioned at least partially within the body, the collet defining a bore between the plurality of jaws configured to receive the tool bit, a wedge surface engageable with the collet, and a sleeve surrounding the body. The sleeve is movable relative to the body to engage the wedge surface against the collet and compress the plurality of jaws around the tool bit.

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 power tool supportable by a lanyard. The power tool includes a motor housing, a motor arranged in the motor housing, a 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 configured to transfer torque from the motor to the output member. The power tool further includes a first fastener securing the front housing to the motor housing and a bracket to which the lanyard is attachable. The bracket is 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.
