When tackling the toughest geological formations, the right drill bit determines whether a project runs smoothly or faces costly downtime. In today’s mining industry, Chinese drill bit manufacturers have emerged as global leaders—offering tools that merge cutting-edge engineering, proven durability, and cost efficiency.

Among these innovators, GREAT stands out as a top manufacturer of high-performance drilling tools in Asia. With years of experience in mining applications, GREAT specializes in heavy-duty Tricone and PDC bits built for the world’s most demanding rock formations.
For open-pit and hard rock mining operations, the GREAT Mining Tricone Rock Bit is a proven workhorse.
Designed to withstand extreme pressure and abrasive conditions, it uses three rotating cones, each fitted with Tungsten Carbide Inserts (TCI) that crush and shear rock efficiently.
This design delivers:
High penetration rates even in the hardest formations
Exceptional wear resistance and impact strength
Stable performance under continuous heavy load
One of GREAT’s biggest advantages is customization. Their engineers can match the bit precisely to your rock type, rig model, and drilling parameters.
Their standard range covers 6 3/4" to 16" diameters—ideal for various blast hole rigs and mining scales.
For different formation types, GREAT provides specific IADC-coded models, such as:
532
632
642
722
Each model reflects a different balance of cutting structure, cone angle, and bearing design, ensuring the perfect match for your geological conditions.
