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.

Firstly, it's crucial to note that a 20-inch drill bit is not your everyday drilling instrument. Its size alone sets it apart, catering to large-scale projects where deep holes are required. The length, excluding the shank, allows for drilling through thick materials like hardwood, metal, or even concrete without the need for multiple passes. The extended reach reduces the risk of inaccuracies and makes it ideal for tasks where accessibility is limited.
