Abstract
An end mill is designed to reduce an amount of cutting fluids to prevent the environmental pollution. Because the end mill includes openings which open along spiral grooves, and the openings communicate with an aperture on the rear end surface of a shank via an intake path, chips generated through the cutting process are aspirated forcibly from the openings when air intake is performed via the intake path, and the aspirated chips can be discharged from the aperture on the rear end surface of the shank. As a result, because the usage of the cutting fluids for discharging the chips can be reduced or minimized in comparison with the conventional technologies, environmental pollution can be prevented.
