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.

Carbon steel drill bits come in three primary types low-carbon, medium-carbon, and high-carbon. Low-carbon steel bits, with a carbon content typically below 0.35%, are more flexible but less durable, making them suitable for softer materials like wood. Medium-carbon bits, with a carbon content between 0.35% and 0.60%, strike a balance between strength and toughness, while high-carbon bits, with a carbon content above 0.60%, offer superior hardness and wear resistance, ideal for drilling into harder materials like metal.
