Key Technical Specifications of the Drill Bit
Customized D125 PDC Water Well Drill Bit
| Category | Technical Specification | Performance / Value Advantage |
| Body Material | Premium S45 Steel | High strength and toughness ensure structural stability and long-term durability under heavy load. |
| Cutting Structure | 1308 Spherical PDC Cutters | Impact-resistant design — Compared to standard flat cutters, spherical cutters offer significantly higher impact toughness, making them ideal for gravel, cobble, and interbedded formations. They greatly extend operational life in varying water-well conditions. |
| Structural Design | 3 Wings / Standard Nozzles | Enhanced based on customer drawings to ensure balanced drilling, stable ROP, and optimized hydraulic cooling and cuttings removal. |
| Special Manufacturing Process | Fully customized per the customer’s hand-drawn sketch | The bit body and cutter placement are manufactured strictly according to the non-standard drawing, ensuring 100% compatibility with the customer’s tools and operating habits. |
| Surface Treatment | Bare steel body (no painting) | As requested by the customer, reduce non-essential surface costs and allocate more budget toward critical cutting materials. |
| Applicable Formations | Quaternary clay, sand, sandy gravel, and light cobble layers | Provides broad adaptability, especially for formations with frequent transitions in water-well drilling. |
