An HDD PDC drill bit is a fixed-cutter drilling tool designed for horizontal directional drilling. It uses polycrystalline diamond compact (PDC) cutters to achieve continuous cutting, delivering higher efficiency compared to traditional roller cone bits.
These bits are widely used in trenchless drilling projects such as pipeline installation, water well drilling, and utility construction.
Best Formations for HDD PDC Bits
• Clay
• Sandstone
• Shale
• Limestone
• Soft to medium rock
• Faster Penetration Rate
• Lower Cost per Meter
• Smooth and Stable Drilling
• Excellent Steering Control
• Longer Service Life
• Bit Size: Customizable
• Blade Count: 3 / 4 / 5 blades
• Cutter Size: 13mm / 16mm / 19mm
• Connection Thread: API standard
• Material: High-strength alloy steel
Custom designs available based on project needs
In complete HDD projects, PDC bits are often used together with tools like PDC Reamer to enlarge the borehole efficiently.
While PDC bits perform well in soft to medium formations, selecting the right design for hard rock requires careful consideration.
