    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.

    Abstract: A rotary impact tool including a motor housing, an electric motor supported in the motor housing, and a drive assembly for converting a continuous torque input from the motor to consecutive rotational impacts upon a workpiece. The drive assembly includes an anvil including an anvil lug, and a hammer that is both rotationally and axially movable relative to the anvil. The hammer includes a hammer lug for imparting the consecutive rotational impacts upon the anvil lug. The rotary impact tool further includes a first printed circuit board assembly including an anvil sensor, a first carrier supporting the first printed circuit board assembly, a second printed circuit board assembly including a hammer sensor, and a second carrier supporting the second printed circuit board assembly.

    Abstract: An impact tool includes a housing with a first and second housing portions and a first handle extending from the first housing portion, a motor supported in the housing, a battery receptacle is located at a bottom end of the first handle, and a battery pack removably coupled to the battery receptacle to provide power to the motor. The impact tool also includes a trigger located on the first handle to selectively energize the motor, a gear assembly, and a drive assembly for converting a continuous torque input from the motor to consecutive rotational impacts upon a workpiece such that the drive assembly is capable of developing at least 1,700 ft-lbs of fastening torque. A gear support is coupled to the first housing portion and the second housing portion and defines a gear case with the second housing portion to enclose the gear assembly and the drive assembly.

    Abstract: A rotary impact tool including a motor having a motor shaft that produces a rotational output to drive a gear assembly and a drive assembly driven by the gear assembly. The drive assembly including a hammer coupled to the motor shaft and an anvil configured to receive an impact from the hammer. The rotary impact tool includes a torque stick coupled to the anvil and configured to limit the amount of deliverable torque to a workpiece in accordance with a torsional stiffness of the torque stick, a position sensor to detect angular displacement of the anvil, and a controller in electrical communication with the position sensor. The controller calculates torque delivered to the workpiece from the impact by multiplying the torsional stiffness of the torque stick and the signal from the position sensor, and control the motor based on the torque delivered to the workpiece.

    Abstract: A bolt tensioning tool includes a housing, an electric motor positioned within the housing, a tensioning assembly connectable to a bolt for applying tension thereto, and a bolt tension monitoring system. The bolt has a threaded portion and a surface. The bolt tension monitoring system includes a transmitter, a receiver, a sensor housing, and a controller. The sensor housing has an inner wall defining a recess that receives the surface of the bolt. The controller determines a dimension of the bold during a tensioning operation and determines the tension in the bolt based on the dimension. The bolt tension monitoring system monitors the tension of the bolt during a tensioning operation. The tension assembly applies tension to the bolt during the tensioning operation.

    Abstract: An impact tool includes a housing, a motor supported within the housing, an anvil extending from the housing, and a drive assembly configured to convert a continuous rotational input from the motor to intermittent applications of torque to the anvil. The anvil includes a body rotatable about a longitudinal axis, a driving end portion configured to receive a tool element over a distal end thereof, and a bore extending through the driving end portion of the anvil in a direction transverse to the longitudinal axis. The driving end portion includes a groove located between the bore and the distal end. The groove includes a curved portion converging toward the distal end and is configured to receive a friction ring such that the friction ring follows a contour of the groove.
