The HDD hole opener excels in hard rock formations with key advantages. Its robust design, often fitted with tungsten carbide inserts, delivers superior abrasion resistance, enduring intense grinding from hard rock. High torque transmission ensures efficient rock fragmentation, reducing drilling time. Precise directional control maintains trajectory stability even in dense, heterogeneous rock, minimizing deviations. Additionally, its adaptive structure suits various hard rock types, from granite to quartzite. The non-excavation nature further reduces environmental disruption, making it ideal for hard rock areas needing minimal surface disturbance.
