In the US, we use WD-40. Besides Water Displacement, it's the only other thing it's good for! (Note: it is NOT a general purpose lubricant!)Tim
Almost anything that cools the cutting edge and provides some kind of lubrication will work. You can use WD40, vegetable oil, engine oil, Vaseline, KY jelly, etc. One thing that does not do very well is plain water.

That's the first time I've seen KY jelly advocated as a coolant!
These handy little reference books below are a must have for anyone involved in the art of swarf creation in my view.
What's the correct feeds and speeds for human flesh?
I now use Kool Mist mixed with water, but before I bought the spray nozzle I used a squirt bottle filled with denatured ethanol. The squirt action knocked off the swarf, and the alcohol evaporating cooled down the work. The trouble was the headache from the ethanol fumes.
Reminds me of another thought...What's the correct feeds and speeds for human flesh? Do you think all those lucky* machinists with a missing finger might know?
