Phillips 66® Koolkut® Spectrum is a general-purpose, active cutting oil developed for medium- to heavy-duty machining of cast iron, stainless steel, high-speed steel, and other alloys. It is specially formulated with high-quality base oils and fortified with sulfur-containing extreme-pressure additives that provide good anti-weld properties and reduced friction at the chip-tool interface, resulting in extended tool life and good surface finishes on the machined parts.
