1. An impact tool comprising:
a motor comprising a stator and a rotor, at least a portion of which is disposed in the interior of the stator and which is rotatable about a rotational axis (AX);
a spindle disposed axially forward of the stator and configured to be rotated in response to rotation of the rotor;
an anvil, at least a portion of which is disposed axially forward of the spindle and in which a bit is mountable;
a hammer adapted to impact the anvil in a rotational direction; and
a housing having a motor-housing part that houses the motor;
wherein:
the impact tool has a maximum tightening torque of at least 140 N·m;
the impact tool has an overall length (La), which is a distance—in a front-rear direction parallel to the rotational axis—between a rear-end portion of the motor-housing part and a front-end portion of the anvil, of 100 mm or less; and
the hammer has a base portion, a front-side ring portion protruding forward from the base portion, and hammer projection portions protruding radially inward from the front ring portion.
