A rock drill is a powerful tool used to create holes in hard materials like rock and concrete. It operates by using a rotating drill bit that can penetrate tough surfaces, making it essential in construction, mining, and quarrying. Rock drills can be handheld or mounted on machinery, depending on the scale of the project. These drills often use compressed air or electricity to function, providing the necessary force to break through solid materials. They are commonly associated with mining operations, road construction, and geological surveys, where precise drilling is crucial for safety and efficiency.
