A non-toxic coolant/lubricant is provided which is specifically designed for use in extremely high-load, high-stress machine operations, such as broaching. The composition of this coolant/lubricant includes about 8 to 15 wt % of molybdenum disulfide (MoS2) powder; about 2 to 6.6 wt % of soap flakes; about 6 to 12 wt % of a liquid polytetrafluoroethylene suspension; and about 66.4 to 84 wt % water. The liquid polytetrafluoroethylene component, which is a water-based suspension of polytetrafluoroethylene, serves as a replacement for toxic CCl4, which has been used to increase lubricity in coolant/lubricants comprising molybdenum disulfide. The replacement of CCl4 with liquid polytetrafluoroethylene in the present composition results in a non-toxic but still highly effective coolant/lubricant.
