  • Rotary cutting tool having a predetermined number of left and right handed helical flutes and end face cutting teeth
    Patent number: 9174287
    Abstract: A rotary cutting tool, having a longitudinal axis, includes cutting and mounting portions. The cutting portion includes an end face surface and a peripheral surface extending therefrom. The peripheral surface includes respective pluralities of main and auxiliary flutes that extend helically with opposite hand about the longitudinal axis. The cutting portion includes a plurality of evenly circumferentially distributed end gashes and a plurality of end face cutting teeth. The number of main flutes and auxiliary flutes are different, each being wholly divisible by, and greater than, the number of end face cutting teeth. In each cross sectional view of the cutting portion an imaginary contour line defined by a peripheral contour of the peripheral surface of one of the end face cutting teeth is in rotationally aligned relationship, about the longitudinal axis, with the peripheral contour of the peripheral surfaces of all other end face cutting teeth.
