Or do they?

I have never seen a astronaut use a drill in a low gravity environment. I have seen a lot of power tools to turn bolt and screws not no drills.
Drills has been used to getting grund samples from the moon but then you have high enough gravity for it not to be a problem.
Are you asking why the astronaut doesn’t spin around in a circle? If there’s significant resistance in whatever they’re drilling, they will have to brace against something to absorb the reaction force from the drill.
Pretty sure the astronauts just hold one to something. There is a bunch of cables outside of the iss for the astronauts to hang ontu
Gravity doesn’t really factor in. The rotational force of the drill is counteracted by the astronaut’s hand/wrist/arm just like a dude running an impact wrench in any mechanic’s shop on the ground. So since the astronaut’s hand is stationary, that rotational force is transferred to the nut/bolt/screw.
