FIELD: machine building. SUBSTANCE: method provides for preliminary moulding a charge on tool case using one-time filling of diamond and metallic binding powders separated from one other, followed by sintering process in moulds of thermal insulating material under condition of temperature stabilization ensured at (1-3)·103 degrees of heating rate and proper magnitude of voltage. EFFECT: increased operating properties of the tool using ensured uniform heating up of diamond bearing layer through all the volume. 2 tbl
