The design of a jack hammer drilling rod is both scientific and practical. It is usually made from alloy steel, ensuring durability and resistance to wear and tear. The rods are precisely machined to maintain a consistent diameter and thread pattern, allowing for seamless attachment to different drill bits and hammer mechanisms. They are often heat-treated to increase their hardness and tensile strength, thereby enhancing their performance in rigorous drilling conditions.

Functionality is paramount in the design of a coupling sleevecoupling sleeve. It must be able to handle not only the torque being transmitted but also any axial or radial loads that may occur. Some designs include rubber or metal elements to absorb shock and reduce noise, further enhancing the performance of the coupling system. Additionally, the sleeve should allow for easy installation and removal to facilitate maintenance and replacement when necessary.
