A power drill is a versatile tool used for drilling holes in various materials, such as wood, metal, and plastic. It operates using an electric motor, which spins a drill bit at high speeds. Power drills come in different types, including corded and cordless models, allowing for flexibility in usage. In addition to drilling, many power drills can also function as screwdrivers by using specific attachments. This makes them useful for tasks like assembling furniture or installing fixtures.
