Contour milling cutter

A cutting tool, for machining printed circuit boards and the like, comprising:

• a cutting part having a longitudinal axis of rotation, an outer surface, and a plurality of staggered teeth formed on said outer surface, said cutting part having a first predetermined number of main cutting grooves formed in said outer surface which extend along said cutting part at a first lead angle and a second predetermined number of divider grooves intersecting said main cutting grooves, said divider grooves extending along said cutting part at a second lead angle, said main cutting grooves and said divider grooves defining said plurality of teeth, said first predetermined angle of said main cutting grooves being substantially equal to said second predetermined angle of said divider grooves, wherein said first predetermined number is a prime number and wherein said second predetermined number is greater than said first predetermined number by two, such that said teeth are staggered as viewed in a radial direction which is perpendicular to said longitudinal axis and such that each of said teeth partially overlaps in said radial direction at least another one of said teeth.
