Soluble Oil

Emulsifiable Metalworking Fluid
Phillips 66®Soluble Oil is a chlorine-free, water miscible metalworking fluid designed to emulsify easily and form a long-lasting, stable emulsion when mixed with water. It provides excellent cooling and lubricity for light- to medium-duty cutting and grinding of ferrous and non-ferrous metals, resulting in extended tool life and good surface finishes on the machined parts. It has been specially formulated to provide enhanced rust protection and greater emulsion stability when used with water qualities of varying hardness.
