This is way off topic, but as a toolmaker in the metal cutting business
for 30+ years and counting, I have to disagree with your statement.
There are many commercial cutting fluids on the market which are far
superior to water and will actually enhance the cutting speed while
protecting the tool edge and producing a better finish. Straight water
is a very bad choice if you value your investment in machine tools!
