What do you call the thing that allows the thing that holds the drill to rotate? I understand that the motor powers the drill, but I would like to know what allows it to rotate in the first place. I am thinking this thing is a generic object that exists in other tools and machines.

The thing that holds the drill is called the chuck.

    @Sayaman, as Jack answered on your other question, the drill contains bearings that hold the chuck in place vertically while allowing it to rotate about its axis. – randomhead May 5 at 3:52
