Down Hole Eccentric Water Well Polycrystalline Diamond Drill Bits With Long Life Span

Our eccentric drill bits are engineered for superior performance in demanding well drilling applications, offering exceptional durability and drilling efficiency.

The eccentric bit features an asymmetrical design where the center deviates from the axis line, creating centrifugal force during rotation to effectively cut hole walls and enlarge apertures. This design is particularly effective for expanding depth or working in easy shrinkage hole sections under extended casing.

• Mining operations and quarry drilling
• Highway construction and mountain reinforcement
• Anchoring and engineering holes
• Geothermal air conditioning installations
• Water well drilling projects
• Compatible with DHD/QL/Mission series impellers

• High Drilling Efficiency: Optimized design for faster penetration rates
• Wear Resistant: Polycrystalline diamond construction extends bit life
• Precision Engineering: Maintains straight drilling paths
• Versatile Operation: Suitable for low to high wind pressure conditions
• Deep Drilling Capability: Engineered for extended depth operations

For complex formations, we recommend using low speed, low feed pressure, and high return air speed parameters. Adjust drilling speed based on rock hardness, looseness, and water content. In particularly loose or fractured formations, reduce feed speed and pressure while frequently removing slag and cleaning holes.
