Abstract
PURPOSE: To enhance exhaust capacity of splash in cutting in a deep hole and to have an accurate boring of small to lage diameter with high feeding rate and high efficiency, by sending a hgh-pressure coolant positively not only to the head part but the tail part of a tool shank.
CONSTITUTION: A high-pressure coolant 10a is pressed forward in such a way as flowing along the outside surface of the central part of a hollow tool shank 1 equipped with a boring head 3 at its tip and also into the opening part 4 of boring head and separately an ejector nozzle 14 is arranged incommunication with the exhaust pipe 13 and oriented towared the opening at the tail end of the abovementioned tool shank 1 and into this ejector nozzle 14 another high-pressure coolant 10b is put in by pressure to press forward the high-pressure coolant positively from the head and tail parts of the tool shank 1 to the splash 17 exhaust pipe 13.
