Hongyue Drill specializes in the R&D and manufacturing of PDC bits and various drilling tools, with products exported to more than 30 countries and regions worldwide. The following six selected project cases cover core application scenarios such as mining, water well drilling, geological exploration, tunnel anchoring, coal mining and directional drilling, demonstrating how we create value for customers with professional technology and rapid response.
Saudi Arabia · Granite Open-pit Mine
A large mining company in Saudi Arabia, one of the country's largest granite producers with an annual output of over 5 million tons. The granite in the mining area has a uniaxial compressive strength of over 200 MPa, classifying it as an extremely hard formation with stringent requirements on bit wear resistance and impact toughness.
Client feedback:"The custom 1308 PDC bit from Hongyue Drill completely solved our efficiency bottleneck in granite mining. Bit life increased by 50% while penetration rate improved significantly, and annual cost savings far exceeded expectations. This was a very successful cooperation."
Brazil · Multi-state Water Well Drilling Projects
A well-known water well engineering contractor in Brazil, running simultaneous water well drilling projects across Sao Paulo, Minas Gerais and other states, drilling hundreds of wells per year. With rapid business expansion, they urgently needed a long-term manufacturer capable of stably supplying high-quality drag bits in large volumes.
Client feedback:"After switching between multiple suppliers, Hongyue Drill is the only partner that simultaneously meets our triple requirements of large volume, high quality and on-time delivery. Three years of cooperation with zero complaints — truly convincing performance."
Nigeria · Complex Fractured Formation Mining Area
A well-known geological exploration company in West Africa, conducting a mineral resource assessment drilling project in a mining area in northern Nigeria. The exploration area has extremely complex geological conditions, dominated by fractured zones and fissure-developed formations, placing extremely high demands on coring tools.
Client feedback:"Hongyue's core bits raised our core recovery rate from under 70% to nearly 100% — an almost impossible task in fractured formations. The high-quality cores directly supported our precise resource assessment."
Australia · Tunnel Anchoring Project
A multinational engineering contractor in Australia, undertaking a large tunnel anchoring project on Australia's east coast. The imported bolting rigs used in the project had special requirements for bit connection specifications that standard market products could not match.
Client feedback:"From scratch to delivery in 15 days — this redefined my understanding of drilling tool manufacturing speed. Even local Australian suppliers could not achieve this. Hongyue is not only fast; the quality fully met and exceeded expectations."
China · A Large Coal Mine in Shanxi
A large coal mining enterprise in Shanxi with an annual capacity of over 10 million tons. The coal face encountered hard coal with gangue interlayers, severely testing the wear resistance and impact toughness of shearer picks, directly affecting mining efficiency and operating costs.
Client feedback:"Since Hongyue's custom picks were put into use, our pick changers no longer need to travel back and forth from the coal face several times per shift. Pick life is significantly extended, saving over a million yuan a year, and mining efficiency has reached new heights. Worthy of long-term cooperation."
Indonesia · Directional Drilling Project
A well-known drilling service company in Southeast Asia, executing a directional drilling project in the Sumatra region of Indonesia. Above the target zone, multiple alternating sand-mudstone layers had to be penetrated, with large variations in drillability and prominent wellbore stability issues.
Client feedback:"This is the most stable directional tricone bit we have ever used. Precise inclination control and greatly extended life — the 8-day cycle reduction translates directly into considerable cost savings. Already recommended for the company's other projects."
