A jackhammer is a heavy, powerful tool used for breaking up hard surfaces like concrete, asphalt, or rock. It combines a hammering action with a rapid, forceful vibration to break through tough materials. Jackhammers are commonly used in construction, demolition, and roadwork for tasks like removing old pavement or digging into solid ground. They are typically powered by compressed air, electricity, or hydraulics and require a steady grip due to their strong vibrations and weight.
