<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 electrical outlet to be powered, while a cordless drill can run on batteries or an external power source. Electric drills are usually heavier than their cordless counterparts due to the weight of the motor, but they tend to have more powerful motors and longer battery life. Cordless drills are typically easier to maneuver around tight spaces and may be quieter than electric drills.
