That is definitely some work holding. And I agree on the Z. I have only broken tools before due to Z screw-ups. Although my speeds and feeds might not be getting me the best life span... I am a little conservative. Too conservative. Any new tools I run through my speed/feed calculator to see what it says. That way I make sure I start off in the right ballpark.

edit: if i ran toolpaths as aggressive as you, work holding would probably be a larger concern for me. My feeds are so weak I could probably double side tape the part to the table.
