The term 'rotary' in the name refers to the unique mechanism that sets it apart from other drilling tools. Unlike traditional drills, a rotary jackhammer employs a combination of rotation and hammering action, making it highly effective in breaking through hard materials like concrete, rock, and masonry. Its operational principle is based on a reciprocating piston, which generates a series of rapid blows, driving a chisel into the surface with immense force.

Corrosion, a pervasive issue that can lead to structural failure and significant economic losses, is a major concern for infrastructure such as bridges, pipelines, and industrial facilities. Traditional materials like steel and concrete are particularly susceptible to corrosion, which can be accelerated by environmental factors such as moisture, salt, and chemicals. This not only shortens the lifespan of these structures but also poses significant safety risks.
