Rotary cutting tool having a cutting edge made of multiple materials

A multi-material cutting tool having a body and a head with a height h and at least one continuous or substantially continuous cutting edge comprising at least two successive different materials, the tool comprising an elongate core about an axis and at least one lip or thread crowned with a continuous or substantially continuous cutting edge, the middle or inner radial portion of the core and the distal portion of the lip or thread being made of a first material enabling a low cutting speed (Vc<50 m/min) and the periphery or outer radial portion of the core of the tool and the proximal portion of the lip or of the thread crowned with the corresponding cutting edge being made of a second material enabling a high cutting speed (Vc<500 m/min), the continuous or substantially continuous cutting edge being overall radial to the axis of rotation of the tool and comprising the first material in the zone closest to the axis of rotation and the second material in the zone further away from the axis, characterized in that the body is made of the first material and in that the core is off-centered in relation to the axis of rotation of the tool.
