EP-Additives

I use coolant additives to improve cutting performance and extend coolant life in deep hole drilling operations. The right additive makes a noticeable difference in tool life, surface finish, and coolant system reliability. Over the years I have tested various additive combinations and developed guidelines for what works in different applications. Types of Coolant Additives and Their Applications Coolant additives serve specific purposes and are not interchangeable. I use four main categories of additives, each with a specific function and application window. ...

I have spent a lot of years watching machinists blame the tool, the feed rate, or the material when the real culprit is sitting right in the coolant tank. Coolant for deep hole drilling is a chemical cocktail, and each additive serves a specific purpose. Understanding what each one does and how they interact is the difference between a process that runs all shift and one that burns through drills before lunch. Here is what I have learned, the hard way. ...
