Cutter device

A cutter device for use in end milling or profile cutting or combined end milling and profile cutting operations, said device comprising:

• an elongated tool body having an elongated flute section having an exposed end;
• a first plurality of cutting flutes which are spiral shaped and which are integral with and extend outwardly from the surface of the section, the flutes in the first plurality being equidistantly spaced apart to define a first uniform outer diameter, the first plurality of flutes extending along said surface from a point intermediate the ends of the body to a first end position on said exposed end, said first plurality of flutes in said first end position defining a first set of cutting blades lying in a first plane of cut for end milling;
• and
• a second plurality of cutting flutes which are spiral shaped and which are integral with and extend outwardly from said surface beyond the first plurality of flutes, the flutes in said second plurality being equidistantly spaced apart to define a second uniform outer diameter which is larger than said first diameter, the flutes in all of said pluralities being interleaved, the second plurality of flutes being usable for profile cutting and extending along said surface from said intermediate point to a second end position on said exposed end, said second plurality of flutes in said second end position defining a second set of cutting blades lying in a second plane of cut for end milling, said first plane of cut lying below said second plane of cut when the body is disposed vertically with the exposed end pointing downward.
