ISO 15 Spindle and Air Tool lubricants. Spindles high speed rotating components create internal friction with-in the lubricant which can elevate temperatures causing the lubricant to break-down prematurely. These lighter viscosity oils have lesser coefficient of friction making them the best choice for these applications.
Because of their Low Viscosity and additive make-up, they are also the perfect choice to be used as an Air Tool Oil. These tools require a thin fluid to carry through the airstream and provide lubrication to all their moving parts.
