Mineral Cutting Oils

Water Soluble Coolants -WS50’s main function is to remove heat from the cutting tool, chip and work piece. The cutting oils are manufactured from highly refined Group 2 base oils that are low in Sulphur content. Group II base oils are defined as being more than 90 percent saturates, less than 0.03 percent sulfur and with a viscosity index of 80 to 120. They are often manufactured by hydrocracking, which is a more complex process than what is used for Group I base oils.
