Absolutely sounds like chatter, and that seems to have been confirmed.
Chatter is a resonance phenomenon. Changing your speeds and feeds may allow you to move outside the resonance. For that reason, always try going faster as well as slower. You just need to get out of the resonant zone.
Changing rigidity of the machine or setup will move the point of resonance too.
You can't really get rid of the resonance. It's only a question of whether it coincides with the speeds and feeds you need to use, at which point it is a problem.
