I tried straight antifreeze in my Keller hacksaw last winter. It didn't
freeze, but I DID get rust. Now I'm using a water soluble oil. I need to
add that antifreeze, now that it's getting cold...

One small reason it might not work is that coolant is also a lubricant, which 
anti freez is not. It's also hard not to get coolant all over your hands and 
occasionally in your face and on your clothes. Anti-freeze is toxic, where 
most synthetic coolants are not. If your going to leave the coolant in the 
mill base for long periods of time, my advice would be to go with a synthetic 
as it won't rot like soluble oil. I use Swisslube blaser 2000 or Wynns 941. 
They're good down to -90f, I hope your shop doesn't get colder than that.
The only drawback is that it's pricey. A five gallon pale is about $90, which 
will make 100 gallons of coolant. This might be a life time supply for some 
people but it's well worth the investment.

You dilute it with water. Their data sheet says it resists cold to -90f, but 
doesn't really make it clear whether that's for the concentrate or the mix. I 
buy it at the local industrial supply stores, they all carry one brand or the 
other. The number for Swisslube is 914-294-3200, I'm sure they can tell you 
their closest distributor and answer your freezing question.
