Technology Empowers Underground Mining! Chongqing Inca Rock Machinery Co., Ltd.'s Tapered Drill Bits Launch with Hard-Core Breakthroughs in Hard Rock Mining Bottlenecks

Recently, Chongqing Inca Rock Machinery Equipment Co., Ltd. officially launched high-performance tapered drill bits specially designed for underground mining scenarios. With precision-adapted structural design and superior working condition adaptability, these bits provide a brand-new solution for improving mining efficiency and optimizing costs, attracting widespread attention from the industry.

As a core spare part for underground mining equipment, the tapered drill bits target the key pain points of hard rock mining. Adopting a composite process of high-purity tungsten carbide cutting heads and high-strength alloy base materials, and undergoing multiple precision machining procedures and extreme working condition tests, their wear resistance is increased by more than 30% compared with traditional products, enabling them to easily tackle high-strength rock formations such as granite and basalt. The product design complies with mainstream industry taper standards including 7°, 11°, and 12°, with a full range of diameters covering 26–60 mm. The tapered self-centering structure effectively reduces drilling deviation, ensuring the accuracy of critical operations such as blast hole and anchor hole drilling. When used with pneumatic rock drills, it can achieve efficient slag discharge, increasing drilling efficiency by more than 25%.

Aiming at the complex underground mining environment characterized by humidity, heavy dust and high impact, Chongqing Inca Rock has made special optimizations to the product details: the cutting heads adopt a hot-press inlay process to enhance stability and avoid falling-off risks; the drill rod connection surface is specially treated to ensure a fitting degree of ≥60%, reducing energy loss; the reserved unobstructed water holes are designed to work with the cooling system to extend service life, significantly reducing the frequency of spare part replacement and equipment downtime. This product is not only suitable for underground roadway excavation and secondary crushing in metal mines and non-metallic mines, but also flexibly compatible with different models of mining equipment to meet diverse construction needs.

Currently, the global mining machinery spare parts market is accelerating its development towards high performance and customization, and the domestic underground mining industry has an increasingly urgent demand for localized replacement of core spare parts. Relying on years of technical accumulation in the mining equipment field, Chongqing Inca Rock has achieved independent core processes for the tapered drill bits launched this time, ensuring stable supply chain, guaranteeing product delivery efficiency, and breaking the dependence on imported high-end spare parts with high cost performance. In the future, the company will continue to focus on the intelligent and green upgrading of underground mining equipment, launch more high-quality spare parts adapted to complex working conditions, and inject strong impetus into the construction of smart mines.
