Abstract:
A machining surface of a machining tool such as a drill is composed of a metal-rich section. A ceramics-rich section is formed centrally in the drill. Further, a gradient section is provided between the ceramics-rich section and the metal-rich section. In the gradient section, the composition ratio of metal is gradually increased from the ceramics-rich section to the metal-rich section. That is, the drill is composed of the gradient composite material in which the composition ratio of ceramics is increased and the composition ratio of metal is decreased inwardly from the machining surface.
