    Abstract: A trigger assembly, for use with a power tool having an electric motor, includes a trigger, a spring configured to bias the trigger towards a first position, a conductor coupled for movement with the trigger, and a printed circuit board. The printed circuit board has an inductive sensor thereon responsive to relative movement between the conductor and the inductive sensor caused by movement of the trigger. An output of the inductive sensor is used to activate the electric motor.

    Abstract: An impact tool includes a housing, a motor supported within the housing, an anvil extending from the housing, the anvil including a body rotatable about a longitudinal axis, a drive end portion configured to receive a tool element over a distal end thereof, and a blind bore extending partially through the drive end portion of the anvil in a direction transverse to the longitudinal axis. The impact tool also includes a retainer configured to at least partially surround the tool element, the retainer having a post configured to extend through the tool element and into the blind bore to inhibit removal of the tool element from the distal end of the anvil, and a drive assembly configured to convert a continuous rotational input from the motor to intermittent applications of torque to the anvil.

    Abstract: A transducer assembly for use in a power tool including a housing, a motor, an output shaft that drives a workpiece about a central axis, and a transmission. The transducer assembly includes a transducer positioned between the motor and the transmission. The transducer including an inner hub being rotationally affixed to the housing, an outer rim affixed to a rotatable component of the transmission, a plurality of webs extending radially outward from the inner hub to the outer rim, and a sensor affixed to each of the webs for detecting strain of each of the webs in response to a reaction torque applied to the transmission from the output shaft. A width of each of the webs gradually tapers from at least one of the outer rim or the inner hub toward a midpoint of each of the webs in a direction perpendicular to the central axis.

    Abstract: An impact tool includes a housing including a front housing coupled to a motor housing portion, a motor supported within the motor housing portion, a battery pack supported by the housing for providing power to the motor, the battery pack having a nominal capacity of five Amp-hours and a nominal output voltage of at least 18-Volts, and a drive assembly supported within the housing and configured to convert continuous torque from the motor to consecutive rotational impacts upon a workpiece capable of developing at least 1,700 ft-lbs of fastening torque. The drive assembly includes a camshaft driven by the motor for rotation about an axis, an anvil extending from the front housing, and a hammer configured to reciprocate along a travel portion of the camshaft between a rearmost position and a forwardmost position to deliver rotational impacts to the anvil in response to rotation of the camshaft.

    Abstract: A rotary impact tool includes 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 comprises a printed circuit board assembly including a sensor that is configured to detect rotation of the anvil. The printed circuit board assembly is spaced from the anvil to define an axial gap therebetween.

    Abstract: An impact tool includes a housing, a motor supported within the housing and having a motor shaft, a drive assembly configured to convert a continuous rotational input from the motor shaft to consecutive rotational impacts upon a workpiece, the drive assembly including a camshaft having a front portion and a rear portion defining a carrier, the rear portion being closer to the motor than the front portion, a thrust bearing engageable with the rear portion of the camshaft, and a gear assembly coupled between the motor shaft and the drive assembly. The gear assembly includes a ring gear and a plurality of planet gears meshed with the ring gear. Each of the plurality of planet gears is coupled to the carrier of the camshaft, and the ring gear rotationally and radially supports the rear portion of the camshaft via the plurality of planet gears.
