In a fluid for electrical discharge machining, a low viscosity mineral or synthetic oil is used as the base oil, to which is added ultrahigh-viscosity oil, the low viscosity oil raising the efficiency of chip removal from the workpiece-to-electrode gap adequately cooling said gap, while the addition of ultrahigh viscosity oil enables the voltage across the discharge electrodes to be increased, allowing an even larger amount of electrical discharge energy to be applied to the workpiece-to-electrode gap, providing a fluid for electrical discharge machining which enables discharge efficiency to be greatly raised and discharge machining speed to be increased.
