Abstract
A tool for chip-forming machining is made by passing first and second compounds through first and second coaxial dies, respectively, whereby the first material forms a center core of the tool, and the second material forms an outer rod of the material. The material of the core is tougher and less wear-resistant than the material of the outer rod. The coaxial first and second compounds are passed through a shaping die and then through a flute-forming structure which forms chip flutes in the outer rod.
