A hammer drill is a power tool designed for drilling into hard materials like concrete and masonry. It combines rotary drilling with a hammering action, allowing the drill bit to break through tough surfaces more effectively. This makes it ideal for construction and renovation projects where traditional drills may struggle. Hammer drills typically have two modes: drilling and hammering. In drilling mode, they function like standard drills, while in hammering mode, they deliver rapid bursts of force. Many models also feature adjustable speed settings and torque controls, enhancing their versatility for various tasks.
