본 발명은 초경 합금 기재를 포함하는 절삭 공구에 관한 것으로, 상기 초경 합금 기재는 WC, 감마상 및 바인더상을 포함하고, 상기 초경 합금 기재는 감마상이 공핍되는 바인더상 풍부 표면 구역을 구비하고, 상기 초경합금 기재의 미세조직에는 그래파이트 및 에타상이 존재하지 않고, 상기 바인더상은 높은 엔트로피 합금이다. The present disclosure relates to a cutting tool including a cemented carbide substrate having WC, gamma phase and a binder phase. The substrate is provided with a binder phase enriched surface zone, which is depleted of gamma phase, wherein no graphite and no ETA phase is present in the microstructure and wherein the binder phase is a high entropy alloy.
