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.

The drill bit, often made of tungsten carbide or steel, is the cutting edge of the tool. It comes in different designs such as button bits, DTH (Down-The-Hole) bits, and PDC (Polycrystalline Diamond Compact) bits, each suited for specific rock types and drilling conditions. Button bits, for instance, are widely used in surface drilling due to their durability and ability to handle softer rocks. On the other hand, PDC bits are ideal for drilling through extremely hard rocks due to their exceptional wear resistance.
