Abstract: A novel end mill is provided. The end mill may include wide double gashes at the tip having a three-tangent radii, as well as variable flute spacing, eccentric side relief or grind, dubbed radius or land, chip breakers, and/or honed cutting edges. These features may be included in various configurations, depending on the end use and desired capabilities. The tip geometry, including the double gashes with blended, three-tangent radii provides increased performance with respect to ramping or plunging operations. The gashes are used to evacuate extraneous chips during milling, and the wide double gashes increase the efficiency of chip removal.

Abstract: A rotary cutting tool that includes an elongated tool body, rotatable along a longitudinal axis of rotation is disclosed. It has a fluted cutting end on one end and a shank end on the opposite end of the tool body. The fluted cutting end includes a nose, a periphery and an end surface that extends from the nose to the periphery. A plurality of axial flutes extends from the end surface to the fluted cutting end and combines with a plurality of cutting edges. The cutting edges are unequally spaced along the circumference of the end surface lying in a plane perpendicular to the longitudinal axis of rotation. In addition, all cutting edges are of a different helix from one another and the cutting edge geometries vary from one another to create a different sound pattern. This reduces resonant harmonic vibrations.

Abstract: Disclosed herein is an end mill capable of preventing an increase in cutting resistance, chipping, or damage due to cutting chip clogging from being generated in each bottom cutting edge having a small pitch in a rotational direction side of the end mill even when the pitches between the bottom cutting edges in a circumferential direction of each thereof differ from one another. An end mill includes an end mill body which is rotated about an axis thereof; an odd number of five or more outer peripheral cutting edges formed around a front end portion of the end mill body; and bottom cutting edges which are formed at the front end of the end mill body so as to respectively extend from the tips of the outer peripheral cutting edges toward the axis, wherein the outer peripheral cutting edges have different helix angles with respect to the axis.
