I have been thinking in moving up to air tool for cutting... but was surprised by the fact that an oiler is needed, but the worst part is that the oil is evacuated in open air... by the tool, near your face... I checked various sites and indeed the comments do not bring an ounce of safety...
What is your enlightened opinion?
it is an old post, but a good beginning:

As I posted under the lubrication for South Bend Lathe topic, There are paraffins in motor oils.
In refrigeration machinery, air tools and firearms where temperatures can be depressed by expansion of gasses or in the case of firearms, by taking them out in the cold, the paraffins will go to a waxy solid and gum up the works.
desergison's synthetic is paraffin-free and the light hydraulic oils are pretty much so. The Marvel Mystery oil has such a strong solvent in it that it will free up anything.
Home shop and light industrial users can get away with more than construction users. The heavy duty rock drills can get the exit air stream so cold that it throws ice chunks.
That brings up another point. Air tool oil not only has to stay oily at low temperatures, but it can't go to snot when mixed with carryover water in the air. I, sadly, have had to de snot several pneumatic systems and it 'snot fun.
End of preview
Electric and cordless seem like a better idea!
