Flat-top PDC Drill Bit

Direct Core Connection Flat Top PDC Bit

Our direct core connection flat top PDC bit is a newly optimized drilling tool engineered for precise and efficient core drilling operations. Different from traditional threaded drill bits that adopt adapter connection and easily cause structural jitter and hole deviation, this upgraded flat top PDC bit features an integrated direct core thread design. It realizes one-piece seamless connection with the core barrel without intermediate connectors, effectively eliminates downhole tool shaking and radial displacement during high-speed drilling.
The unique flat-top cutting structure distributes drilling pressure evenly on the rock surface. It avoids the problem of unilateral force deviation that often occurs with concave and arc-shaped drill bits, thoroughly solving common construction problems such as hole deflection, inclined holes and wandering drilling tracks. With uniform cutting resistance and continuous and steady footage speed, the bit maintains consistent drilling efficiency in long-term continuous operation, greatly reducing secondary hole trimming and rework costs.
The bit body is forged with high-strength integral steel and matched with high-wear-resistant PDC composite cutters. It integrates impact resistance, wear resistance and pressure resistance, adapting to complex and changeable downhole environments, with outstanding durability and long service life.

Applicable Drilling Formations

This flat top core-connected PDC bit is professionally optimized for soft and medium-hard composite formations. It performs excellently in loose and medium-density rock layers, including silt soil, weathered slate, soft sandstone, mudstone, conglomerate, loose limestone and layered fractured rock formations. It is the ideal drilling tool for conventional non-hard rock core drilling projects.

Application Working Conditions & Projects

This versatile PDC bit is widely used in civil and engineering drilling scenarios, with strong scene adaptability:
  • Water Well Engineering : Rural domestic water wells, agricultural irrigation wells, industrial shallow water supply wells, residential area water well reconstruction projects
  • Geological Drilling : Field geological survey, engineering geological exploration, core sampling drilling
  • Construction Engineering : Foundation detection drilling, slope support anchoring holes, road and bridge preliminary exploration holes
  • Portable Drilling Operations : Suitable for small and medium-sized portable drilling rigs, light crawler drilling equipment, applicable for field mobile construction with limited space

Popular Sales Countries & Markets

Benefiting from its stable performance, cost-effectiveness and strong anti-deviation ability, our flat top direct connection PDC bit has won wide recognition in global grassroots drilling engineering markets. It is hot-selling and highly praised in Southeast Asia, Africa, South America and Eastern Europe, including Vietnam, Thailand, Tanzania, Uganda, Bolivia, Ecuador, Bulgaria and other countries. It is the preferred conventional drilling bit for local drilling contractors, engineering teams and drilling tool distributors.
