Disclosed is a machining fluid admixture for cooling and lubricating a workpiece/tool interface, wherein the admixture comprises a major amount of n-propyl bromide and a minor amount of a lubricant. In other embodiments, the machining fluid consists essentially of about 30.0 to about 99.99 weight percent n-propyl bromide; from about 0.01 to about 30.0 weight percent of a lubricant; and optionally from 0.0 to about 70.0 weight percent of a fluorinated chemical. In still further embodiments, the machining fluid consists essentially of about 45.0 to about 50.0 weight percent n-propyl bromide; from about 0.01 to about 2.0 weight percent of a lubricant; and from 45.0 to about 50.0 weight percent of a fluorinated chemical. In other aspects, the present invention is directed to methods for cooling and lubricating a tool/workpiece interface. The methods comprise the steps of applying an effective amount of the n-propyl bromide-based machining formulations as disclosed herein to a part during a machining operation so as to cool and lubricate the tool/workpiece interface.
