What tool is characterized by having a battery pack to eliminate the need for an extension cord?

The cordless drill is designed to operate using a rechargeable battery, which allows for enhanced mobility and versatility during electrical and construction tasks. The battery-powered nature of this tool eliminates reliance on external power sources, such as extension cords, making it ideal for use in various locations, including tight spaces or outdoor areas where power outlets may not be readily accessible.

Cordless drills are particularly useful for drilling holes, driving screws, and performing various tasks without the hassle of managing cords, enabling the user to work more efficiently and comfortably. This feature distinguishes the cordless drill from other types of drills, such as electric or pneumatic models, which often require a continuous power supply or compressed air, respectively, limiting their portability.
