Zusammenfassung:	A self-directing nozzle of a drill bit of a downhole tool and method are disclosed. The drill bit with the nozzle may be used to form a wellbore in a subterranean formation. The drill bit has a passage for fluid to pass through. The nozzle includes a case positionable in the passage of the drill bit and a movable body movably positionable in the case. The movable body has a channel for passage of the fluid therethrough. The channel has a non-linear shape with a channel axis extending therethrough. The channel axis is curved to define a spiral flow path therethrough whereby the fluid passing through the channel facilitates rotation of the movable body within the passage of the drill bit.
