Abstract
The drill includes a motor, a spindle rotatable with a rotational force transmitted from the motor, a clutch assembly that disables transmission of the rotational force to the spindle in response to a rotational load on the spindle reaching a release value and including an elastic member that adjusts the release value, and a change ring switchable from a clutch mode in which the clutch assembly is operable to a nonclutch mode in which the clutch assembly is inoperable in response to the change ring operated in a forward rotation direction. In the clutch mode, the elastic member elastically deforms to reduce the release value in response to the change ring operated in the forward rotation direction, and to increase the release value in response to the change ring operated in a backward rotation direction.
