Drill accessories are tools and attachments that enhance the functionality of a drill. They include items like drill bits, which come in various sizes and types for different materials, such as wood, metal, or masonry. Other accessories include chucks, which hold the drill bits securely, and depth stops, which help control how deep the drill penetrates. Additionally, there are sanding drums for smoothing surfaces, hole saws for creating larger openings, and screwdriver bits for driving screws. These accessories make drilling tasks more efficient and versatile, allowing users to tackle a wide range of projects with ease.
