it's impossible to come to any kind of assumption as to what the problem is without any information as to what you are trying to make the tool do .
one thing i will point out is , unless the solid holder is of poor quality i would rule out that being the problem ,#1 reason for that being is they are far more rigid than any collet holder , i work with a lot of nasty stuff at high speeds or at heavy loads when chatter become a problem the tool gets mounted in a solid holder period ,and the shorter the better . but if it's piss poor quality then forget it , same thing goes for cheap collet holders.
you need to tell us the depth of cut ,engagement , tool stickout , what the part is being fixtured in (how solid), what is the wall thickness if pocketing etc in order to get a truely educated guess as to what the problem may be .
there are so many factors that will contribute to tool chatter
a simple trick of mine with chattering endmills is to ever so slightly run a stone along the sharp edge of the endmill ,just enough to lighten the edge some ,works like a charm , sharp isn t necessarily always a good thing
