PDC Bit (Polycrystalline Diamond Compact Bit) 

PDC bit (short for Polycrystalline Diamond Compact bit) is a fixed-cutter rotary drill bit, widely used in modern oil & gas, mining, and geothermal drilling operations.

PDC steel body drill bit is an efficient drilling tool widely used in oil, gas, and geothermal well drilling. Its unique design and material combination enable it to perform well under various geological conditions, making it widely suitable for rapid drilling operations in various geological formations.

Structure

• PDC Cutters: The key component. Each cutter is a composite disk made of a thin layer of synthetic polycrystalline diamond sintered under ultra-high pressure and temperature onto a tough tungsten carbide substrate.
• 
• Bit Body: Usually made of steel or tungsten carbide matrix, designed with multiple blades (e.g., 3–9 blades) to hold the PDC cutters.
• Nozzles: For drilling fluid (mud) flow to cool cutters, lubricate, and carry cuttings to the surface

Working Principle

PDC bits break rock by a shearing action as the bit rotates. The sharp, hard diamond edges slice through the formation rather than grinding or crushing it. This delivers high penetration rates (ROP) with lower weight on bit (WOB) compared to roller-cone bits.

Bullet Points

1.High Quality PDC Cutters

We adopted high-performance polycrystalline diamond compact (PDC) cutters with high hardness, abrasion resistance and thermal stability, ensuring fast drilling speed and long service life.  08, 09, 10, 13, 16, 19 and other general specifications, and various customized specifications of PDC cutters all available for the PDC bits.

 2.5-Wing Stable Structure

5-wing reinforced matrix/steel body design reduces vibration and ensures straight boreholes. Excellent hole stability and low deviation rate for long well sections.

·3. Optimized Hydraulic & Flushing System

Large flow channels and anti-clogging flute design improve cuttings removal efficiency and prevent bit balling in clay and sticky formations.

· 4.API Standard Thread Connection

Standard API REG/IF thread ensures perfect compatibility with most water well drilling rigs and drill pipes, easy installation and reliable connection.

5. Wide Application for Water Wells

Ideal for soft to medium formations such as sandstone, shale, clay, marl and loose gravel. Widely used in water well drilling, irrigation wells and geothermal boreholes.
