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, allowing for efficient and precise drilling. Power drills come in different types, including corded and cordless models, making them suitable for both home and professional use. In addition to drilling, many power drills can also function as screwdrivers by using specific attachments. This feature makes them useful for assembling furniture or performing repairs. Common brands of power drills include DeWalt, Makita, and Bosch, each offering a range of models to meet different needs.
