HAINAISEN Ships 15 Units of 8-3/4" Five Blade Wing Oil Drilling Bits to Boost Energy Exploration Projects
On January 22, 2026, the production base of Shaanxi Hainaisen Petroleum Technology Co., Ltd. in Xi'an was abuzz with orderly activity. After rigorous quality inspection and professional packaging, 15 units of 8-3/4" Five Blade Wing Oil Drilling bits were officially loaded and dispatched to a key oilfield cooperation project. This batch of drill bits, tailored to the customer's specific operational needs, is set to provide reliable and high-performance equipment support for deep oil exploration operations in complex geological environments.
As a professional enterprise with 20 years of focus on drill bit R&D, production, and sales, HAINAISEN has always adhered to market demand-oriented product development. The Five Blade Wing Oil Drilling bit delivered this time is a core product independently developed by the company for medium to hard formation exploration. It adopts a patented cutter geometry with premium tungsten carbide materials and an optimized five-blade asymmetric design. The scientifically arranged cutting teeth, combined with precision machining by 5-axis machining centers and CNC machine tools, effectively disperses cutting stress during drilling, significantly improving mechanical drilling speed while extending the bit's service life. Its unique spiral waterway design enhances cuttings removal efficiency, preventing bit balling and ensuring stable operation even under extreme downhole conditions—fully reflecting HAINAISEN's strength in engineered drill bit solutions for harsh environments.
According to HAINAISEN's technical director, the 8-3/4" Five Blade Wing Oil Drilling bits shipped this time strictly comply with API international standards. The bit body is integrally formed with high-strength steel and hard alloy matrix, undergoing 72 hours of rigorous tests including pressure resistance, wear resistance, and vibration resistance. All performance indicators have reached leading industry levels. "This product has been validated through numerous field applications, winning consistent praise from customers for its high drilling efficiency, long service life, and low wear rate," the technical director emphasized. "The smooth delivery of this batch is a testament to customers' recognition of our precision manufacturing capabilities and product quality."
The sales director of HAINAISEN stated, "The trust from customers drives our continuous progress in drill bit technology innovation. Over the years, our dedicated R&D team has been committed to optimizing the performance of the Five Blade Wing Oil Drilling bit—integrating cutting-edge industry technologies with on-site construction experience to enhance its adaptability to diverse formations and operational cost-effectiveness. We support full customization and OEM/ODM services, and with our advanced production workshops covering 3,500m² and efficient supply chain management, we ensure fast delivery within 3 to 5 days for standard and customized orders alike."
The successful shipment of these 15 Five Blade Wing Oil Drilling bits marks HAINAISEN's mature capabilities in large-batch production and on-time delivery of medium and large-sized oil drill bits. Looking ahead, HAINAISEN will continue to uphold the principles of "precision manufacturing, professional design, and fast delivery," continuously upgrade product performance, and provide integrated technical solutions for global customers in oil & gas extraction, mining, and water well drilling fields. This delivery not only strengthens the cooperative relationship with the current customer but also lays a solid foundation for expanding market share in the international energy equipment sector.
