Aluminum Milling Coolant ( AGAIN!!! )

And I apologize for being so harsh over what seems like a minor issue, but spreading false information is obviously a pet peeve of mine.

I could also blame the late hour, but I refuse to blame alcohol for my own boorishness! ;-)

One more thing that flood coolant is good for, is at washing the milling area down for cleaning.

One of the machining magazines I get had a picture of a mill using the LN2 fed through the center of the tool with a special attachment something like what you use when you don't have through the spindle coolant option. I forget which one.

FWIW: "Tractor hydraulic fluid" is generally cheaper than ATF

Also, O'reilly's has this stuff for $ 29.99 ( but I suggest do double check the msds to make sure that it's primarily mineral oil base stock )

Pure Guard - Hydraulic Oil Part # N1032 Line: OIL

Additionally, a person could buy a gallon of heavy cutting oil and then mix with either straight hydraulic oil or with atf--purchase the darkest heaviest shit that you can find--but just be careful about chlorine and / or sulphur additives as staining can be an issue with non-ferrous.
