Led by XTC Luoyang Top Hammer Tools R&D Department and monitored by engineers throughout, the tests were conducted under real mining conditions. At the gold mine in Shandong, the drill rods were paired with various drill rigs including Epiroc and Gaiya as well as rock drills 1838 and 23K across different platforms. The data showed a maximum cumulative footage of 3,192 meters across 12 working faces. Most drill rods failed through normal wear, with service life extended 1–2 working faces longer than the existing products on site, demonstrating overall superior performance. To date, the gold mine has since placed a batch order for the drill rod, the market acceptance rate has been further enhanced.
At the iron mine in Liaoning, which presented challenging conditions with multiple layers and highly variable rock hardness, the drill rod worked stably with XCMG drill rigs and 18U, 1838 rock drills, showing no premature or mid-term failures. The testing rods achieved a cumulative footage of 3,830 meters, with a maximum of 16 consecutive working faces, reaching an industry-leading level. Customers reported that XTC Luoyang drill rods offer clear advantages in efficiency and longevity, with more consistent quality than currently used products, making them highly suitable for large-scale replacement.
These two real tests fully confirmed that our MFH35‑T38R32‑4305 drill rod delivers long life, high adaptability, and exceptional reliability under various conditions—including hard rock, soft rock, and complex stratified formations. It is compatible with mainstream rock drilling equipment and meets the core requirements of efficient mining and cost reduction.
As an innovator in the cemented carbide tool industry, XTC Luoyang remains committed to integrating R&D with market needs and advancing the domestic replacement of mining rock drilling tools. The success of these tests marks another breakthrough in thread design, material processing, and product reliability. Looking ahead, XTC Luoyang will continue to focus on customers, optimizing product performance and service systems, and delivering more efficient, durable, and cost-effective rock drilling solutions for mining and construction applications, thereby supporting high-quality industry development.
