Is there some reason why a rotary tool spins so that dust/shavings

Or maybe I'm using it wrong? Seems that either I need to use the
cutting tool with my left hand or to put the project on the right
side of my right hand.

Thank you.
I think it's because the Dremel uses tools originally developed for
stationary machines. And the reason the chips fly at you is because
you are using the wrong side of the cutter. What you should do is hold
the part in your left hand, but have it inverted so that the cutting
action takes place on the bottom of the part and the chips fly away
from you.
