What is a "hammer drill"?

A hammer drill is a power tool designed for drilling into hard materials like concrete, stone, or brick. It works by combining the spinning motion of a regular drill with a rapid forward pounding action, allowing the drill bit to break through tough surfaces. Hammer drills are commonly used in construction and renovation projects where heavy-duty drilling is required. They are especially useful for tasks like installing anchors or drilling holes for wiring and plumbing in hard surfaces.
