Button bits for down-the-hole drills
SK06G/SK06S Grade: This grade of material is sourced from a leading German tungsten carbide manufacturer. Compared to high-quality domestic raw materials, this tungsten carbide exhibits distinct advantages in terms of particle size distribution, impurity control, crystal morphology management, and overall technical performance metrics. Building on our existing expertise, our company has meticulously optimized the alloy products, resulting in solutions that not only outperform competitors in wear resistance but also deliver groundbreaking improvements in impact toughness and thermal fatigue resistance. Based on extensive, long-term comparative use by customers, these products have demonstrated exceptional performance when tackling both hard rock formations and geologically complex strata.
SK06: This grade is a traditional product of our company, backed by over 20 years of manufacturing experience. It’s a highly mature and stable product that delivers outstanding performance in terms of its overall capabilities.
