Rotary cutting tool

A rotary cutting tool with a longitudinal axis of rotation, having a cutting head formed with at least two chip evacuation flutes and at least two body portions, each body portion being formed between two adjacent chip evacuation flutes, said body portions carrying, at a front face of the cutting head, a plurality of cutting inserts, each cutting insert having an operative cutting edge and being mounted so that its operative cutting edge lies substantially in a plane perpendicular to said axis of rotation;

• a first body portion of said two body portions carrying a first outer cutting insert and a second body portion of said two body portions carrying a second outer cutting insert, the operative cutting edge of the second outer cutting insert being substantially shorter than the operative cutting edge of the first outer cutting insert, outermost ends of the operative cutting edges of the first and second outer cutting inserts being substantially equidistant from said axis of rotation and being spaced therefrom at a distance defining a cutting radius of the cutting tool,
• wherein the first and second outer cutting inserts are identical and have major and minor cutting edges, the first outer cutting insert being mounted so as to present its major cutting edge in an operative position and the second outer cutting insert being mounted so as to present its minor cutting edge in an operative position.
