Slow speed as well.

Exactly.

If people had ever seen some charts comparing varying cutting tool speed and
feed pressure, and the resulting wear on the tool, they would be amazed.

In summary, you run your tools too fast, and they go up in smoke in a hurry.

If you ever have to guess, guess on the side of slower tool speed and more
pressure.

Of course, getting a real chart with the tool, material, and the correct
tool speed and feed speed or pressure it the "best" way to go at it. g

Of course misidentifying metals is always a gas. Storing hardened
tool steel in the same place as free machining stainless makes for some
rather interesting experiences. Not that I have ever done it or anything
