What is a Jackhammer?

A jackhammer is a heavy-duty power tool used to break hard surfaces such as concrete, asphalt, rocks, and pavements. It works by delivering strong and repeated hammering actions to the surface. Jackhammers are widely used in construction, demolition, and repair work where manual tools are not effective.

Jackhammers can be electric, pneumatic (air-powered), or petrol-powered, depending on the type of work and location. Due to their high impact force, they can easily break materials that are difficult to cut or drill.
