A nozzle through which a liquid coolant is discharged is provided with an outer tube, a projecting member and an inner tube disposed inside the outer tube, and an elastic body disposed between the inner tube and a discharge port of the outer tube. If foreign matter accumulates on a nozzle opening of the inner tube, the elastic body is compressed by the inner tube under the pressure of the coolant, so that the inner tube moves toward the discharge port. Consequently, the projecting member penetrates the nozzle opening, thereby automatically removing the foreign matter accumulated on the nozzle opening.

An applicator for applying cutting fluid is mounted in a CNC machine for pre-programmed, computer controlled use as a tool.
