    I'm not following any of this logic. The tool is following a path that is instantaneously tangent to the intended workpiece interface point, and the vector relationship between the tool centerline and the cutting edges is fixed by diameter and RPM, not by the toolpath. If anything I would think the observations of less chatter when slowing the tool centerline velocity (IPM) down would be better explained by inertia and backlash?

    The reduced shank tools work because there is no simultaneous contact on the upper flutes.
    Depth you can get away with depends on flute helix angle as this changes the way this works.
    Very simplified and not quite correct, too many cutting edges in contact and you get chatter.

    So did mine. They did not do well in corners and even trying to push one on a slight turn to the trailer would result in the tires "winding up" and it would spring back at ya.
    A u-turn under power and the entire body would lift and twist lifting close to foot in a crazy fashion until one tire broke free and slipped.
    Most people don't have a spool and 14 inch wide slicks so they expect the car to turn.
    You can't road race with a spool. Go fast, go straight.

    Worked great for me.
