<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 with an electric drill, you need to plug it into an electrical outlet in order to operate it, while a cordless drill can be powered by either rechargeable batteries or an external power source such as a wall socket. Additionally, electric drills tend to have more power than their cordless counterparts and are generally heavier and bulkier.
