The 6-inch and 6-1/2-inch (152mm – 165mm) PDC drill bits are the absolute workhorses for water well contractors across the Middle East, North Africa, and Sub-Saharan regions. Designed for fast penetration in soft-to-medium rock formations, these sizes offer the perfect balance between drilling speed and overall operational cost.
As a dedicated B2B manufacturing factory based in China, we do not sell stock generic bits. Instead, we specialize in 100% Made-to-Order custom engineering, ensuring every bit is perfectly optimized for your specific geological challenges.
Why Water Well Contractors Choose Our Custom 6″ & 6-1/2″ PDC Bits:
- Tailored to Local Geologies: Whether you are drilling through soft shale in Iraq, abrasive sandstones in Saudi Arabia, or limestone layers in Egypt, we optimize the cutter density (13mm or 16mm premium cutters) and blade count (3, 4, or 5 blades) to prevent bit balling and maximize footage.
- Heavy-Duty Forged Steel Body: Machined on advanced CNC equipment from high-strength alloy steel, our bodies feature superior hardfacing protection to combat erosion in high-velocity drilling fluids.
- Optimized Fluid Hydraulics: Custom nozzle configurations and large junk slots ensure excellent cutting removal, keeping the cutters cool and substantially extending the lifetime of the drill bit.
Our Full Customization Process (How We Work):
Since we run a specialized production line with zero pre-made inventory, we offer a streamlined 4-step custom manufacturing cycle to global buyers:
- Technical Consultation: You provide us with your desired bit size (6″ or 6-1/2″), API connection type (e.g., 3-1/2″ API Reg), and details of the formation or rock hardness.
- 3D Engineering Drawing (Within 48 Hours): Our technical team will generate a precise 3D blueprint for your review and approval.
- Precision CNC Manufacturing (15-30 Days): Upon deposit confirmation, we initiate top-tier manufacturing using premium raw materials and high-impact diamond compacts.
- Rigorous QC & Global Shipping: Every bit undergoes ultra-strict quality checks before being securely packed for air or sea freight straight to your destination.
