<p>An end mill tool has two distinct sets of flutes, a low-helical angle set of two-or-more primary flutes (210) and a high-helical angle set of two-or-more secondary flutes (220, 222, 224, 226). At positions on the body of the tool where these two sets of flutes intersect, a plurality of discrete cutting edges (240, 242, 244, 246) are formed.</p> |
