General Purpose Soluble Metalworking Fluid
  • Versatile, multi-metal compatible
  • Low scumming performance in hard water environments, providing cleaner working conditions
  • Low foam performance in soft water conditions, eliminating the use of antifoams
  • Effective biocide system, to prevent bacterial degradation, and extend coolant life
  • Boron free and reduced residue characteristics
  • Chlorine, phenol, and nitrite-free


Callington Calcool S1 oil is a chlorine and boron free, general-purpose soluble metalworking fluid.

Its high mineral-oil content and the unique additive package provides excellent lubrication properties, forming a milky type emulsion, providing consistent performance in a wide range of water types.


Callington Calcool S1 is suitable for use in small to medium general machine shops, where general machining operations, on a range of materials, require a stable product, offering versatility at a reasonable cost.
