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.
