Milling Fail, and my Nuub mistake… Help with - Speeds, feeds and how this VN12 should sound?

As always Cal, great info. My guess is it's a combination of all of these areas. The cutter is out for regrinding ( only slab cutter I have) and I will most definitely practice on softer material. Knock on wood, don't think I broke anything and I'm further up that steep learning curve. Still smiling!

I did a hardness test on a Chinese AXA tool holder, it came out at 30 Rc, 100 sfm would be too fast, I'd start at about 40 sfm and about .003 feed per tooth.
