CONSTITUTION: An automatic cut-off nozzle for supplying cutting oil for processing materials comprises a nozzle(A), an angle regulating part(B), and a body part(D). The nozzle has a screw groove(102) formed on the outer side of a feed part(101) and one or more suction holes(103) formed on the opposite side of the feed part. The angle regulating part comprises a fixing bracket(110), a free rotating unit(20) which is coupled to an inner fixing groove(201) of the fixing bracket, and a ball plunger(210). The body part comprises a joint socket(60), a ball(50) which is inserted in the joint socket and engaged with a contact surface of the joint socket, an elastic spring(40) which is fixed to a spring fixing groove(602) so that the ball is always in contact with the contact surface, and a rubber packing which presses the ball plunger to one side of the joint socket formed on the outer side of an oil inlet hole.
