Let me toss another tid bit of info which I found out the hard way .Don't use cutting oil in place of some type of coolant when cutting hard steel .The danged oil shields the part and drives the heat in  .Tool steel will get so hard the only way to cut it is with ceramic tooling which I have but most people don't .In addition the harder it gets the less machinabilty it has .

If nothing else give it a shot of water from a mist bottle .I myself can get water soluable coolant by the bucket full if I need  to for nothing .I just get a few ounces and mix it up as I need it which isn't that often .

Now you could use something like "tap Magic " which cools by evaporation but then you are breathing the fumes which I don't think is especially healthy . On occasion I have used WD -40 but I had a fan going at the time .
