The "Thatlazymachinist" on YouTube had a video that explained that the
purpose of cutting oil was to enhance the flow of the chip on the face
of the cutting tool. I posted this comment question, but I'm getting
impatient & I expect that someone here has the answer.

Quote:

If cutting oil helps the chip flow along the face of the tool, it needs to be ON the face of the tool. But if it is applied to the stock ahead of the cut, how does it get from the surface of the stock to the face of the tool? This seems especially unlikely given that the chip is in constant contact with the face (how would oil get between them?)?

Thanks,
Bob

It flows on. It only takes a thou or two to float a chip
