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