Abstract: An impact tool is less likely to have a shorter service life. An impact tool includes a motor, a spindle, a hammer, an anvil, and a lid. The spindle is rotatable by the motor. The spindle has an opening in a rear end face of the spindle, an internal space extending frontward from the opening and including a first space containing a lubricant oil and a second space connecting to a rear end of the first space, and a first feed port in an outer circumferential surface of the spindle. The hammer surrounds the spindle. The anvil is strikable by the hammer in a rotation direction. The lid is placeable through the opening into the second space. The first feed port allows supply of the lubricant oil from the first space to between the spindle and the hammer.
