The drill doesn't pull you down. The equilibrium is achieved by (roughly speaking) (the force that the drill bit pushes the ground) = (the force that the ground pushes the drill up) = (the force that you push the drill down) = (the force that the drill pushes you up) = (the force that the Earth pulls you down). The Earth's gravity on your body enables all this force; without it you need to invent some other way of pushing down the drill.
