Which power tool is used for drilling holes with an external power supply?

The portable electric drill is designed specifically for drilling holes and operates using an external power supply, making it a versatile tool for various tasks in construction and woodworking. This tool typically features a rotating drill bit that allows it to create holes in different materials such as wood, metal, and plastic, depending on the type of drill bit used. The power supply enhances its drilling capability compared to manual alternatives, making it more efficient and effective for completing projects that require precision and speed.

In contrast, the other tools listed serve different functions. A jigsaw is primarily used for making intricate cuts in materials, rather than drilling holes. The portable circular saw is intended for cutting straight lines in wood and other materials, rather than creating holes. Pruning shears focus on cutting and trimming plants and branches, which doesn't involve drilling at all. Understanding the specific function of each tool is crucial for selecting the right one for a given project.
