End mill with independent rake surfaces

A cutting tool comprising:

• a body of generally cylindrical shape extending along a longitudinal axis between a leading end and an opposite trailing end, the body having a clamping region disposed at or about the trailing end of the body and a cutting region extending toward the clamping region from the leading end of the body;
• a plurality of flutes defined in the body, each of the flutes extending in the cutting region from the leading end of the body toward the coupling portion;
• a plurality of end cutting edges disposed at the leading end of the body, each end cutting edge extending from at or near the longitudinal axis outward along a respective flute of the plurality of flutes to a respective corner cutting edge located at an outer periphery of the leading end;
• and
• a plurality of peripheral cutting edges, each peripheral cutting edge extending from the respective cutting corner rearward toward the coupling portion along the respective flute of the plurality of flutes,
• wherein a first end cutting edge of the plurality of end cutting edges is defined, inpart, by a plurality of rake faces, each rake face extending from a portion of the first end cutting edge into the respective flute,
• wherein the plurality of rake faces comprises a first rake face disposed at a first axial rake angle and a second rake face disposed at a second axial rake angle different than the first axial rake angle,
• wherein a portion of the first end cutting edge corresponding to the first rake face is disposed at a first radial angle;
• and wherein a portion of the first end cutting edge corresponding to the second rake face is disposed at a second radial angle different than the first radial angle, and
• wherein the first end cutting edge extends from a first end at or about the longitudinal axis to an opposite second end, wherein the portion of the first end cutting edge corresponding to the first rake face is disposed at the first end of the first end cutting edge, and wherein the first radial angle is positive.
