Precision Drilling for Aggregate, Dimension Stone, and Building Materials Production.
MSD (Zhuzhou Jingde Machinery Co., Ltd.) delivers high-performance drilling tools engineered for modern quarry operations. From aggregate production to dimension stone extraction, our DTH hammers, DTH bits, and top hammer systems conquer abrasive granite, limestone, and sandstone formations with superior service life and consistent hole quality. Trusted by quarry operators across 50+ countries, MSD tools combine OEM-grade quality with China factory pricing—helping you extract more material at lower cost per ton.
High-volume aggregate quarries drilling blast holes in the 50-120mm range demand maximum output with minimal downtime. In abrasive granite and hard limestone, rapid gauge wear and carbide button loss drive up bit consumption—directly impacting your cost per ton.
For quarry blast holes (50-120mm), our DTH systems deliver consistent hole quality and extended bit life. The best-selling QL60 hammer + 152mm bit configuration offers wide compressor compatibility and optimal drilling efficiency. With premium YK05 tungsten carbide buttons and reinforced gauge protection, MSD bits deliver 30-70% longer service life. In an Australian granite quarry, our 5-inch DTH bits achieved over 800 meters per bit—reducing bit changes by 40%.
Smaller quarries and secondary breaking operations need cost-effective tools for holes under 50mm. Fast cycle times and easy rod handling are critical when drilling hundreds of holes per shift with limited crew and equipment.
For small holes (≤50mm), Top Hammer systems offer faster rod handling and lower cost per hole. Our tapered button bits (28-42mm) are ideal for small quarry blasting and secondary breaking. For larger production holes (38-120mm), our threaded button bits feature Retrac design that reduces stuck drill string incidents by over 90%. With body breakage rates below 0.1%, MSD top hammer tools deliver reliable performance shift after shift.
Dimension stone quarrying requires precise hole patterns for controlled splitting. Hole deviation ruins block integrity, and excessive vibration causes micro-fractures that devalue premium granite, marble, and sandstone products.
We provide precision-ground DTH bits with optimized face designs for straight hole drilling. Our flat-face and concave bit profiles minimize hole deviation to under 1% in depths up to 20 meters. For splitting operations requiring smaller holes, our tapered button bits feature friction-fit self-tightening—the harder you hit, the tighter it grips—ensuring consistent energy transfer for clean block extraction.
Limestone and softer formations drill fast but create unique problems: rapid cuttings buildup, bit balling in wet conditions, and uneven wear patterns that reduce hole quality and increase fuel consumption.
For soft to medium rock (up to 100 MPa), either Top Hammer or DTH systems work effectively—choose based on hole diameter and depth requirements. Our DTH bits feature aggressive flushing channels and dome-face profiles to prevent clogging. For Top Hammer applications, our threaded button bits with optimized button spacing deliver faster penetration while maintaining clean hole bottoms. MSD's valveless DTH hammers eliminate valve failures that cause unexpected downtime across entire drilling campaigns.
