Severe Machining Without Sulfur Or Chlorine No Stink, No Rust
Circle Cut #729 was designed to lubricate without using conventional additives such as sulfur and chlorine. This required some new test methods to be designed, and in the end a uniquely powerful cutting oil was created.
Traditional sulfurized additives show a definite perfromance plateau. This plateau can be extended by blending different types of sulfur, or using sulfur in conjunction with fat or phosphorous.
Circle Cut #729, using a phosphorous complex, shows a performance plateau, but it is dramatically higher than any sulfur technology tested (and we tested them all).
Chlorinated additives do not show a performance plateau. This is what makes them so popular. Need a better oil? Add more chlorine. However, chlorine does present several issues. Health, safety, environmental and disposal issues are the top four, but in process rust is a big problem. From a blender's viewpoint, there is also a practical limit as how much chlorine can be used due to the viscosity and solubility of the additive.
Circle Cut #729 will outperform any chlorinated cutting oil up to 15% by weight of chlorine. And making a cutting oil with 15% by weight of chlorine will cost more than Circle Cut #729 and you still have the health, safety, environmental, disposal and rust problems.
Bottom line? Circle Cut #729 beats ANY sulfurized cutting oil and any practical amount of chlorine.
Using Circle Cut #729
Circle Cut #729 is a neat oil, intended to be used as supplied.
Certain other additive technologies will prevent Circle Cut #729 from working, so it cannot be added to other cutting oils and nothing should be added to it. It cannot be improved.
Due to this sensitivity issue, the tank needs to be drained, and ideally flushed. The results will make the effort worthwhile.
