Reliable Borehole Drilling for Domestic, Agricultural, and Community Water Supply.
MSD (Zhuzhou Jingde Machinery Co., Ltd.) provides reliable drilling tools for water well and borehole applications. Our DTH hammers, DTH bits, and casing systems handle challenging formations—from loose overburden to fractured rock—trusted by well drilling contractors across 50+ countries.
Drilling through sand, gravel, clay, and fractured rock causes hole collapse before casing can be installed. In water-bearing formations, conventional drill-then-case methods fail—leading to stuck tools, lost holes, and costly re-drilling.
For unstable or water-bearing formations, DTH + Casing systems are essential. Our best-selling DHD350 hammer + 152mm bit + ODEX casing configuration is proven reliable in mixed formations. The ODEX eccentric system enables simultaneous drilling and casing in a single pass. For most overburden conditions, ODEX delivers 80% of Symmetrix capability at 60% of the cost—the industry rule of thumb for casing selection.
When drilling encounters boulders in overburden, eccentric casing systems struggle to maintain hole stability. Large cobbles deflect the pilot bit, causing deviation and potential tool damage that can strand an entire drilling project.
When boulders are present, concentric casing (Symmetrix) is required. Our Symmetrix ring bit system cuts a full-diameter hole symmetrically, powering through boulders without deflection. MSD has verified delivery of 800mm and 1000mm concentric systems for Southeast Asian bridge foundation projects reaching 50+ meters through mixed boulder and clay layers—the same technology applies to challenging water well sites.
In stable, competent rock, adding casing increases cost and complexity unnecessarily. Deep agricultural and irrigation wells (100-300+ meters) require high penetration rates to minimize rig time—every extra component slows the operation.
For stable rock formations, DTH systems without casing deliver maximum drilling efficiency. Our valveless DTH hammers eliminate internal valve failures—the leading cause of unexpected downtime. The DHD-series (low-pressure, 8-12 bar) suits smaller compressors, while QL and SD-series (high-pressure, 17-30 bar) provide faster penetration in deep wells. In a South African water well project, our 6-inch DTH system achieved 12-15 meters per hour in stable sandstone.
Small-diameter domestic wells (115-152mm) require cost-effective tools that still deliver reliable performance. Many contractors face tight budgets but cannot afford tool failures that delay project completion and damage customer relationships.
For water well drilling in the 115-325mm diameter range, our DTH + Casing systems provide overburden protection at competitive cost. The DHD350 hammer delivers reliable performance on smaller rigs with limited air capacity. With sub-1% comprehensive failure rates and premium YK05 carbide inserts, MSD tools help small contractors compete on quality while controlling costs—OEM quality at China factory price.
