A press of the trigger activates the electric motor, which in turn spins the drill or screwdriver bit. Increased power results in increased torque, also known as rotational force, on the drill and screwdriver. It is recommended that your drill comes with a rechargeable battery, a plug-in charger, and, of course, the actual drill itself. Drills are most frequently used to drill holes and to drive screws and other tiny fasteners into the ground or into solid surfaces. A power drill will be your best option for completing the majority of tasks, from hanging a mirror to constructing a bench. Drills can also be used to cut wood with a router bit if the chuck is not sharp enough.
