Carbide Matrix Flat Top PDC Bit (For Hard & Intact Formations)
Oil-Grade PDC
Long Service Life
Hard Formation Specialized
The Carbide Matrix Flat Top PDC Bit features a sintered carbide matrix body combined with super-strong oil-grade PDC cutters, specifically engineered for hard and intact formations. With exceptional wear resistance, impact resistance, and powerful cutting performance, this bit significantly extends service life in hard formations while ensuring stable and efficient drilling. Ideal for non-coring applications including grouting holes, gas drainage holes, water wells, and geothermal drilling.
Widely used in grouting hole drilling, gas drainage hole drilling, water well opening and completion, shallow geothermal drilling, and foundation engineering drilling in hard and intact formations. Particularly suitable for hard formation applications with high demands for bit life and drilling efficiency.
Core Advantages
Carbide Matrix · Extended Service Life
The entire matrix is sintered from high-grade carbide material, offering superior hardness and exceptional wear resistance. Outstanding impact and abrasion resistance significantly reduces matrix wear rate compared to conventional steel-body bits, preventing cracking and spalling, extending service life in hard formations, and reducing bit change frequency and operational costs.
Super-Strong Oil-Grade PDC · Efficient Rock Breaking
Equipped with premium oil-grade PDC cutters featuring upgraded diamond layer thickness and bond strength. Enhanced cutting sharpness and impact resistance deliver high rock-breaking efficiency in hard and intact formations, minimizing cutter chipping and loss. Maintains stable cutting performance in high-hardness rock layers for faster drilling speeds.
Flat Top Design · Stable Drilling & Smooth Borehole
Unique flat-top structure ensures even force distribution and minimal radial vibration during drilling, providing exceptional drilling stability and smooth borehole walls. Ideal for grouting holes and gas drainage holes requiring consistent borehole quality. Reduces risks of deviation and sticking, ensuring continuous efficient drilling operations.
Non-Coring Design · Focused on Efficiency
Non-coring drilling structure eliminates coring requirements, maximizing drilling efficiency. Compared to core bits, achieves over 30% faster drilling speed in hard formations, significantly reducing single-hole drilling time. Perfect for large-scale rapid drilling projects where sample collection is not required.
Multi-Hardness Adaptation & Complete Size Range
Specifically designed for hard and intact formations with adaptability for F≤8 (medium-hard) and F≤11 (hard) hardness grades. By combining different specifications of super-strong oil-grade PDC cutters, flexibly addresses various hard rock formations. Covers complete size ranges from small to large diameters, compatible with different drill rig models. Thread types are customizable to meet various application needs.
Applications
Suitable Formations
Hard and intact formations such as limestone, dolomite, white sandstone, and coal seams.
Adaptation hardness grade: F≤8 (medium-hard formation), F≤11 (hard formation), achieving efficient rock breaking through super-strong oil-grade PDC cutters.
Not recommended for loose & broken formations, highly abrasive formations, and ultra-hard formations with F＞11.
Drilling Method
Rotary Drilling – Recommended to use mud circulation or high-pressure clean water circulation to ensure adequate bit cooling and efficient cuttings removal. Adjust drilling pressure and rotation speed according to formation hardness (F≤8/F≤11) to further improve drilling efficiency and bit life.
