Abstract: A tool member includes a tungsten carbide based cemented carbide substrate and a diamond coating deposited on the substrate. The substrate has two diffraction peaks K.alpha..sub.1 and K.alpha..sub.2 indexed by index of pane (211) for tungsten carbide in X-ray diffraction. The peaks satisfy the relationship of 1.sub.1 /1.sub.2 .ltoreq.35, where 1.sub.1 and 1.sub.2 are heights of the peaks K.alpha..sub.1 and K.alpha..sub.2 measured from a base of a trough between the two diffraction peaks. For manufacturing the tool member, a green compact is first sintered to provide a tungsten carbide based cemented carbide substrate. Subsequently the substrate is ground and subsequently heat-treated at a temperature between 1000.degree. C. and 1600.degree. C. in a vacuum or in a non-oxidizing atmosphere. Thereafter, a diamond coating is formed on the substrate by vapor-deposition method.

Abstract: There is disclosed a surface-coated tool member of tungsten carbide based cemented carbide which has a tungsten carbide based cemented carbide substrate and a hard coating formed on the substrate. The hard coating may have one or more layers each of which is made of one material selected from the group consisting of carbide, nitride and oxide of metals in groups IV.sub.A, V.sub.A and VI.sub.A of the Periodic Table; solid solution of said carbide, nitride and oxide; and aluminum oxide. The cobalt content of the substrate in a surface portion at a depth of about 2 .mu.m from a surface thereof is less than that in an interior portion at a depth of about 100 .mu.m from said surface by at least 10%.
