Saf-T-Cool 451

Saf-T-Cool 451 is a high performance universal bio-stable coolant. It utilizes state of the art ingredients to provide long sump life without the use of tank side additives. Foul odors and the typical “Monday Morning” (rotten egg) odors are eliminated. Saf-T-Cool 451 has extraordinary hard water emulsion stability and rejects tramp oil for proper removal. Its natural low foam characteristics make this acceptable in high pressure systems, along with low mist characteristics creating a safe working environment. Saf-T-Cool 451 uses advanced generation additive technology for superior surface finishes plus increased tool life. The product is designed for cutting and grinding a wide range of ferrous and non-ferrous alloys. It constantly rinses the machine as it runs eliminating any sticky residues and leaving a very light oily film on the machine surfaces. SF WAY LUBES are recommended as the machine lubricant to help maintain proper system health.
Universal Emulsion


Saf-T-Cool 451 forms a premium quality micro-emulsion for machining and grinding. Starting dilutions for machining operations should be between 5 – 10%. For grinding operations, the suggested starting dilutions should be between 4 – 6%. Make-up fluid is typically added at half the target concentration. For proper mixing it is recommended that Saf-T-Cool 451 concentrate be added to water with agitation
