The greater the inertia of the projectile, the more energy you are
likely to lose at the point of impact (noise, heat, vibration,
deformation of the components etc), and the less forward velocity you
will impart on it. The more vibration etc, the more energy dissipated
into the operator which is both inefficient and fatiguing.


The reasoning is a bit cockeyed here. The reason you don't want a drill
chuck, is because the drill chuck mechanism cannot handle the high
impact loads without the jaws of the chuck slipping and the chuck
mechanism being damaged. The energy imparted to the tip of the drill bit
in a normal chuck, will to a first approximation, be the same. This is
why SDS drill chucks are specifically barred from impact usage.
