    Abstract: In at least one illustrative embodiment, a rotary impact tool comprises a motor including a rotor and an input shaft coupled to the rotor for rotation therewith about an input axis, an anvil configured to be rotated about an output axis and including an output shaft, a carrier driven by the input shaft and having a passage extending through a distal end thereof, and a hammer supported and driven by the carrier and configured to impact the anvil to cause the anvil to rotate about the output axis. The anvil may comprise a blade coupled to the output shaft and configured to direct a lubricating fluid through the passage when the anvil or carrier rotates about the output axis.

    Abstract: Illustrative embodiments of tool extensions and methods of using such tool extensions are disclosed. In at least one illustrative embodiment, a tool extension may comprise a drive core configured to transfer rotational torque from a first end to a second end opposite the first end, where the first end is configured to be removably coupled to a tool to receive rotational torque from the tool, the second end is configured to be removably coupled to a fastener to supply rotational torque to the fastener, and the drive core is bendable between the first and second ends. The tool extension may further comprise a shell surrounding the drive core and containing an electro-rheological (ER) fluid configured to transition between a flexible state in which the shell permits bending of the drive core and a rigid state in which the shell resists bending of the drive core.

    Abstract: A power tool includes a button useful to select a direction of rotation of the power tool. The button can be used to select between forward, reverse, and neutral. The power tool includes a housing which is coupled with an abutment structure which engages with the button. A sawtooth engagement is formed between the abutment structure and the button. The sawtooth engagement can be asymmetric in shape to provide different force vectors depending on whether the button is pushed in a first or a second direction. The sum of the resistive forces can be the same whether the button is pushed in the first or second direction, owing to the asymmetric forces caused by the sawtooth engagement which make up for differences in other internal resistive forces.
