A power drill is a versatile tool used for making holes in various materials like wood, metal, and plastic. It operates using an electric motor, which spins a drill bit at high speeds. This makes it much easier and faster to create holes compared to using a manual hand drill. Power drills often come with different attachments, allowing them to also drive screws and perform other tasks. There are two main types of power drills: corded and cordless. Corded drills plug into an electrical outlet, providing continuous power, while cordless drills run on rechargeable batteries, offering more mobility. Both types are essential for DIY projects and professional construction work.
