Milling aluminum??

[BADVELLE]

Another home remedy for lubrication while machining, sawing or drilling aluminum is to use a bar of hand soap. Ivory works well, I have a bar out in the shop for a stand by.

WD 40 works very well and is an easy clean up. The Tap Magic, for me anyway, stinks and if you get it on you, you will smell it all day long.

I have always used bees wax on tools like my files when working on aluminum.
