An aqueous machining fluid admixture comprises water, a sulfurized oil and a water soluble salt of a dimercaptothiadiazole wherein the weight ratio of the sulfurized oil to the water soluble salt of dimercaptothiadiazole is in the range of from about 15:1 to about 45:1. A method employs the fluid by applying the fluid at the interface between tool and workpiece in shaping or working operations of metallic and solid non-metallic workpieces. The fluid is particularly effective in grinding operations to produce improved grinding ratios.
