<human>: What is the difference between an electric and a cordless drill?
<bot>: The main difference between an electric and a cordless drill is that an electric drill requires an external power source, usually an electrical outlet, while a cordless drill has its own rechargeable battery. Electric drills are generally more powerful than cordless drills, but they require more time to charge and can be heavier. Cordless drills are lighter and easier to carry around, making them ideal for smaller jobs.
