    摘要： 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.

    摘要： Milling cutter (1), which can rotate about a cutter longitudinal axis (A), comprises a sleeve-shaped shaft (2) provided with an inner lying chip evacuation channel (11), which is arranged, in essence, symmetric to the cutter longitudinal axis (A), and with a suction opening (12). The milling cutter also comprises a milling head (3, 3a, 3b, 3c), which is held coaxial to the cutter longitudinal axis (A) and to the shaft (2) while being held on said shaft and which comprises, as cutting edges (7, 9), a face cutting edge (7) and a peripheral cutting edge (9). At least one cutting edge (7, 9) forms a positive rake angle (γa, γr) on the periphery of the milling head (3, 3a, 3b, 3c). The milling cutter (1) is particularly suited for machining light metals, especially for circular milling. The abstract of the disclosure is submitted herewith as required by 37 C.F.R. §1.72(b). As stated in 37 C.F.R. §1.72(b): A brief abstract of the technical disclosure in the specification must commence on a separate sheet, possibly following the claims, under the heading “Abstract of the Disclosure.” The purpose of the abstract is to enable the Patent and Trademark Office and the public generally to determine quickly from a cursory inspection the nature and gist of the technical disclosure. The abstract shall not be used for interpreting the scope of the claims. Therefore, any statements made relating to the abstract are not intended to limit the claims in any manner and should not be interpreted as limiting the claims in any manner.
