Chongqing IncaRock Upgrades Underground Mining Threaded Drill Rod Spare Parts to Boost Efficient and Low-Consumption Mine Operations

Chongqing, January 29, 2026 (PR Newswire) — Chongqing IncaRock Machinery Equipment Co., Ltd. (hereinafter referred to as "IncaRock") today launched a new generation of specialized threaded drill rod spare parts for underground mining. Featuring high-torque connection, fatigue resistance, wear resistance, and quick assembly-disassembly design, the product is precisely tailored for underground deep-hole drilling, blast hole construction, water and gas exploration operations in metal mines and coal mines, helping mines improve drilling efficiency and reduce downtime and maintenance costs.

Core Upgrades: Three Major Technological Breakthroughs for Extreme Working Conditions

Targeting the "high-load, dusty, and highly corrosive" extreme working conditions of underground mining, the new-generation threaded drill rod achieves three core technological breakthroughs:

1. High-Strength Material and Heat Treatment: Adopting integral quenching and tempering of R780-grade high-strength alloy steel, the thread area is strengthened by deep quenching, with a tensile strength exceeding 689MPa. Its fatigue resistance and wear resistance are improved by more than 50% compared with conventional products, suitable for deep-hole drilling operations in hard rock over 200 meters.

2. Precision Thread and Sealing Design: Launching a full range of thread systems including R32/R38/T38/T45, the taper accuracy is controlled within ±0.02mm/25.4mm. Combined with high-sealing joints, it ensures stable transmission of high torque, effectively reducing the risk of thread fatigue fracture and liquid leakage, and improving assembly-disassembly efficiency by 40%.

3. Efficient Slag Discharge and Anti-Jamming Structure: Optimized design of large-lead spiral grooves and thickened rod body increases slag discharge efficiency by 35%, reducing repeated cutting at the bottom of the hole. Equipped with anti-seize joints and positioning pins, it significantly reduces the probability of drill jamming and drill tool loss, especially suitable for soft coal seams and fractured zone formations.

Scenario-Adaptive: Full Working Condition Coverage, Seamless Compatibility with Mainstream Equipment

IncaRock's threaded drill rod spare parts are available in multiple length specifications from 1.5 to 6 meters, compatible with mainstream top-hammer/dth drills such as Atlas Copco and Furukawa, meeting the needs of different mining processes:

• Hard Rock Deep-Hole Drilling: Higher rigidity ensures straighter drilling, reducing hole deviation and blasting blind areas, and improving ore recovery rate;

• Soft Formation Operations: Fast slag discharge and low resistance reduce the risk of drill sticking, extending drill bit life by 15%–20%;

• Harsh Environment Adaptation: Sulfur-resistant and corrosion-resistant materials are optional, suitable for sulfur-containing mines and complex hydrogeological conditions, extending the service cycle.

Service Upgrade: Full-Life Cycle Guarantee to Reduce Comprehensive Costs

Backed by ISO 9001:2015 quality system certification, IncaRock provides 1-year warranty and full-life cycle technical support for threaded drill rod spare parts: establishing a "spare parts inventory early warning + rapid response" mechanism, the Chongqing headquarters and service centers in North China and Northwest China can achieve emergency supply within 72 hours; at the same time, it offers on-site inspection, thread repair, and drill tool matching optimization services, helping mines reduce the comprehensive ownership cost of drill tools by more than 20%.

Corporate Vision: Innovation-Driven, Empowering Green Mining

IncaRock has long been engaged in the field of underground mining equipment, adhering to the R&D philosophy of "Efficiency, Reliability, and Low Carbon" and continuously promoting product iteration. The upgrade of this threaded drill rod spare part not only strengthens the company's competitiveness in the underground mining spare parts market but also provides a solution that balances efficiency improvement and safety guarantee for the mining industry.

In the future, IncaRock will continue to focus on customer needs, expand the application of technologies such as intelligent monitoring and customized materials, and inject new momentum into the safe, efficient, green, and low-carbon development of the global mining industry.
