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.
