Drill Faster. Last Longer. Maximize Penetration Rates and Lower Your Cost Per Meter.
MSD (Zhuzhou Jingde Machinery Co., Ltd.) delivers high-performance rock drilling tools engineered for the demands of modern mining operations. From open-pit blast hole drilling to underground development, our DTH hammers, DTH bits, and top hammer systems conquer hard rock formations (f=15+) with superior penetration rates and extended service life. Trusted by mining contractors across 50+ countries, MSD tools combine OEM-grade quality with China factory pricing—helping you drill more meters at lower cost per hole.
Large-scale open-pit operations require blast holes in the 120-200mm diameter range through abrasive hard rock (200+ MPa). Low penetration rates and frequent bit changes drive up cost per meter—the metric that matters most to production managers.
For large blast holes (>120mm), DTH systems deliver straighter holes and better energy transfer at depth. Our best-selling SD6 hammer + 165mm DTH bit configuration provides the optimal balance of drilling speed and cost efficiency. With premium YK05 tungsten carbide buttons and reinforced gauge protection, MSD bits deliver 30-70% longer service life compared to standard tools. In a Russian iron ore project (f=18 hardness), this configuration achieved 340 meters per bit with zero failures.
Underground face drilling and tunneling typically require smaller holes (38-120mm) with fast cycle times. Premature shank adapter breakage, hole deviation, and stuck drill strings are critical bottlenecks in confined spaces.
For holes ≤50mm, Top Hammer systems offer faster rod handling and lower cost per hole. Our threaded button bits (38-120mm) are engineered for jumbo drilling with a proprietary dual-hardening heat treatment—achieving body breakage rates below 0.1%. The Retrac design reduces stuck drill string incidents by over 90%, verified in Canadian hard rock tunneling operations.
High-volume production drilling in iron ore, copper, and gold mines demands maximum meters per shift. The most popular blast hole sizes (146mm, 165mm, 178mm) require consistent penetration rates and minimal downtime from tool failures.
Our SD-shank DTH hammers are the preferred choice for large-scale blasting (120-200mm). The valveless design eliminates internal valve failures—the leading cause of unexpected downtime. Combined with our DTH bits featuring sub-1% comprehensive failure rate, mining contractors typically achieve 15-20 meters per hour penetration in medium-hard formations. MSD delivers OEM-equivalent performance at 30-50% lower total cost of ownership.
Mineral exploration demands hole straightness through fractured, unstable, or water-bearing formations. Drilling through boulders in overburden risks hole collapse and compromised geological data—failures that can derail entire exploration programs.
For fractured or unstable formations, DTH + Casing systems are essential. Our ODEX-type eccentric casing handles most overburden conditions—delivering 80% of concentric capability at 60% of the cost. When encountering boulders in overburden, our concentric casing (Symmetrix) systems handle diameters up to 800mm—verified in Southeast Asian bridge foundation projects with 50+ meter depths through mixed boulder and clay layers.
