    Abstract: An anvil is for use with an impact tool. The anvil includes an impact receiving portion having a lug configured to be impacted to rotate the anvil about an axis, a drive portion opposite the impact receiving portion, and a shank extending between the impact receiving portion and the drive portion. The drive portion is configured for coupling to a tool bit. The shank includes a necked portion having a reduced diameter. The necked portion is located adjacent the drive portion and between the impact receiving portion and the drive portion.

    Abstract: Position sensing related to a component within a power tool. The component within the power tool is, for example, a hammer of an impact mechanism and can include one or more sensible features that allow a controller of the power tool to precisely determine the position, speed, and acceleration of the component. One or more sensors can be used to determine the rotational position of the hammer and the axial position of the hammer. The rotational position of the hammer can then be used to calculate, for example, rotational speed and acceleration of the hammer. With precise determinations of the rotational and axial position of the hammer, the controller of the power tool is able to precisely time the impact between the hammer and the anvil to optimize the impact between the hammer and the anvil (e.g., to maximize energy transfer between the hammer and the anvil).

    Abstract: An anvil for an impact tool includes a body rotatable about a longitudinal axis, a driving end portion configured to receive a tool element over a distal end thereof, the driving end portion including a bore extending through the driving end portion of the anvil in a direction transverse to the longitudinal axis, and a groove located between the bore and the distal end. A friction ring is disposed within groove and includes a curved section extending toward the distal end.

    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. 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 second performance ratio of the rotary impact tool, defined as (ηa x RPMno-load/Inertiahammer) x (1/216,000,000) is greater than 2.

    Abstract: A powered fastener driver includes a driver blade movable from a top-dead-center (TDC) position to a driven or bottom-dead-center (BDC) position for driving a fastener into a workpiece and a drive unit for providing torque to move the driver blade from the BDC position toward the TDC position. The drive unit includes an output shaft. The powered fastener driver also includes a rotary lifter engageable with the driver blade. The lifter is configured to receive torque from the drive unit in a first rotational direction for returning the driver blade from the BDC position toward the TDC position. The powered fastener driver further includes a kickout arrangement located between the lifter and the output shaft. The kickout arrangement is configured to permit limited rotation of the lifter relative to the output shaft between a first position and a second position.

    Abstract: An impact tool includes a housing extending along a longitudinal axis, the housing including a motor housing portion and a front housing coupled to the motor housing portion, a motor supported within the motor housing portion, and a drive assembly supported within the housing. 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. An axial distance between the forwardmost position and the rearmost position of the hammer is at least 20.75 millimeters, and the travel portion of the camshaft has a diameter of at least 25 millimeters.
