Advanced Button Technology

Advanced Button Technology

The Numa120 DTH hammer bit features state-of-the-art button technology that revolutionizes drilling performance. Each tungsten carbide button is precisely engineered and positioned using computer-aided design to ensure optimal rock breaking efficiency. The buttons undergo a specialized hardening process that enhances their wear resistance while maintaining sufficient toughness to prevent breakage. The unique spherical design of the buttons provides maximum penetration while distributing impact forces evenly, reducing stress on the bit body. This advanced button configuration allows for superior cutting action in various rock formations, from soft limestone to hard granite. The buttons are secured using a proprietary mounting technique that significantly reduces the risk of button loss during operation, a common issue with conventional bits.
Innovative Flushing System

Innovative Flushing System

The flushing system incorporated in the Numa120 DTH hammer bit represents a breakthrough in drilling efficiency. The system features carefully calculated air channels that optimize the flow of compressed air around the bit face and buttons. This enhanced air flow design ensures effective removal of drill cuttings while simultaneously cooling the buttons during operation. The flushing ports are strategically positioned to create a cyclonic effect, preventing regrinding of cuttings and reducing wear on the bit face. The system maintains consistent air pressure throughout the drilling operation, preventing bit binding and ensuring smooth operation even in wet conditions. This innovative design significantly reduces the risk of button overheating and extends the overall life of the drilling components.
Durability and Reliability

Durability and Reliability

The exceptional durability of the Numa120 DTH hammer bit is achieved through a combination of advanced metallurgy and precision engineering. The bit body is manufactured from specially formulated steel that undergoes multiple heat treatment processes to achieve optimal hardness and toughness. The shoulder design incorporates reinforced zones that resist cracking under high-impact conditions, while the thread connection features enhanced wear resistance to maintain integrity during extended use. The bit's robust construction includes thick wall sections in critical areas to prevent premature failure, and the entire assembly is subjected to rigorous quality control testing. This attention to durability translates into longer service life, reduced replacement costs, and improved reliability in challenging drilling conditions.
