摘要： PROBLEM TO BE SOLVED: To improve the toughness of the alloy while its sufficient deformation resistance and wear resistance are maintained by forming a binder of Co of a specified amt. contg. only Ni and Fe on impurity standards. SOLUTION: In the case of being circulated to ordinary finish turning and profile or finish milling or the like for steel including light discontinuous cutting, the content of Co in a binder is controlled to 9 to 12 mass %, preferably to 9 to 10.5 mass %. There is a need of sufficiently increasing the solid solution in the binder, and for this purpose, a hard layer is embodied by a method of dissolving W atoms into Co. In this alloy system, the binder is essentially composed of a Co-W solid solution. Ordinarily, the solid solution strengthening is directly measured as relative magnetic saturation. By reducing the content of carbon in the alloy, the solid solution strengthening increases, but it reaches the maximum at the relative magnetic saturation of about 0.75 and is no longer increased. The relative magnetic saturation shall most preferably be held to
