An impact tool () includes: a motor (); a spindle (), which is disposed forward of the motor and is rotated by the motor; a hammer (), which is supported by the spindle; an anvil (), which is impacted in a rotational direction by the hammer, a motor housing (), which houses the motor; a grip housing (), which extends downward from the motor housing; and a battery-holding housing (), which is disposed at a lower-end portion of the grip housing and holds a battery pack () having a rated voltage of 18 V. The distance (Da) between a rearward-most edge of the motor housing and a frontward-most edge of the anvil is 97 mm or less.

Impact tool

An impact tool includes: a brushless motor; a spindle, which is rotated by the brushless motor; a hammer, which is held on the spindle; an anvil, which is impacted in a rotational direction by the hammer, a polymer housing, which houses the brushless motor; a hammer case, which is connected to the polymer housing and houses the hammer and the spindle; and a light unit, which is held on the hammer case and comprises a plurality of light-emitting devices. The maximum tightening torque of the anvil is 1,000 N·m or more and 2,500 N·m or less.
