Talk about a finish change with a simple tool swap
I was running some 6061 parts on our Haas VF-2 last week and could not get the surface finish to look right no matter what feeds I tried. Swapped out my standard carbide end mill for a high-feed insert cutter on a whim, and the difference was night and day after just one pass. The chatter disappeared and the parts had that almost mirror look I usually only get with a separate finishing op. Has anyone else seen that big of a jump just from changing tooling geometry?

The 0.001" finish tolerance I saw on my last 6061 job just vanished when I threw in a 2-flute high helix end mill. I went from a 32 Ra that looked like a rough sandcast to a 16 Ra that was almost reflective. It was like flipping a switch, the harmonics just settled right down. Never had a tool swap make that much difference in my life.
