390 Cutting Oil

Chesterton 390 Cutting Oil is a heavy-duty, oil-based cutting fluid designed to improve tool life and deliver cleaner, more precise cuts in tough machining applications. Its thick, high-viscosity formula clings to tools and surfaces, even in vertical or overhead positions, reducing friction and helping prevent galling, welding, and tool wear. The result is smoother finishes, better surface quality, and added rust protection, all without harsh fumes or strong odors.

Formulated with extreme-pressure additives, 390 Cutting Oil works effectively on a wide range of metals, including carbon steel, stainless steel, and high-performance alloys. It is NSF registered for industrial use and ideal for drilling, tapping, boring, and similar operations where dependable lubrication and cooling are critical.
