I thought that new tool coating was just hype until I ran a test part

We got a sample end mill with this fancy new coating, AlTiN-X, about three months ago. The sales guy said it would run 30% faster in steel, which sounded like total nonsense to me (you know how they are). I was sure it would just burn up. So I set up a test on a 4140 part we run all the time, running the coated tool at the speeds they suggested and a regular one at our normal rates. The regular tool was done after 45 parts. The coated one? I ran it for 120 parts before I stopped the test, and it was still cutting fine. The finish was better too, with less built-up edge. I had to eat my words. Has anyone else tried a tool coating that actually lived up to the big talk?

Man, I've been that skeptical guy too many times. I swore a new coolant was snake oil until it doubled my tool life on aluminum. Sometimes the new stuff actually works, what's the wildest claim you've seen turn out to be true?

My old boss swore by that ceramic coating for cars.
