just getting geared up for some large production run on CNC mill for 6061 Aluminium. With that, I would like to know what the general accepted best coolant for milling, drilling and tapping is?
Please respond with name, manufacturer and part # if you could please. I have used Milicron Cimcool and Fastenal Sharpcool synthetic BLUE. What else would you guys recommend?
Thanks, John
