Empowering Efficient Underground Mining Operations: Chongqing Inca Rock Machinery Equipment Co., Ltd. Achieves Technological Breakthroughs in Threaded Drill Bits

Recently, Chongqing Inca Rock Machinery Equipment Co., Ltd. launched a new generation of threaded drill bits as spare parts for underground mining equipment. With high-strength material and innovative structural design, the product provides a new cost-reducing and efficiency-enhancing solution for the mining industry, facilitating the upgrading of intelligent mine construction.

Focusing on the core needs of hard rock drilling in underground mining, this threaded drill bit adopts high-density tungsten carbide alloy for drill teeth, with a hardness of HRA≥92 and a strength exceeding 2800N. Combined with the optimized tooth arrangement structure and forged shell, its wear resistance is more than 5 times higher than that of traditional products. Equipped with 32 types of precision threaded connection structures, the drill bit is compatible with a variety of hydraulic top-drive rock drills, ensuring stable connection and anti-falling performance, and can effectively resist vibration and impact in high-torque operating environments. The innovative dual-airhole slag discharge design and multi-ball bearing layout make drilling in hard rock fractured formations smoother, reducing the sticking rate by 70% and increasing drilling efficiency by 25% compared with ordinary drill bits. The maintenance-free service life of a single drill bit can reach 400-500 meters, significantly reducing equipment downtime for replacement.

As a key spare part for drilling blasting holes and support holes in underground mining, this threaded drill bit is widely applicable to underground mining scenarios such as metal mines and coal mines, and performs particularly well in complex rock formations with high quartz content and strong abrasiveness. Its precise centering design controls the hole diameter error within ±1mm, which can significantly improve blasting effect and project quality. Meanwhile, the coarse rock debris slag discharge design reduces the dust concentration in the working face by 60%, complying with the green mine construction standards.

Currently, China's mining machinery parts industry is embracing high-quality development opportunities. The market scale is expected to reach 162 billion yuan in 2025, with the demand for high-end wear-resistant parts continuing to rise. The newly launched threaded drill bit by Chongqing Inca Rock not only fills the gap in the regional high-end spare parts market for underground mining, but also helps reduce the industry's dependence on imports through localized technological breakthroughs. In the future, the company will continue to focus on the needs of deep mining, intelligent mines and other scenarios, deepen material and structural innovation, and provide more reliable equipment spare part solutions for global mining customers.
