ABSTRACT:
A rotary cutting end mill is provided. The end mill includes a shank section and a fluted section. The fluted section has a first end integrally attached to the shank section, a second end, and an outer surface. One or more helical teeth are disposed along the outer surface of the fluted section. Each helical tooth has a cutting surface and a relief wall that intersect to form an angle defining a helical cutting edge. The helical cutting edge defines an outer circumferential cutting path. The cutting surface includes first, second, and third sections, and first and second take-off peaks. The first take-off peak is disposed between the first section and second section. The second take-off peak is disposed between the second section and the third section.
