Applicable Strata
The C0609 Conical PDC Cutter performs exceptionally well in:
- Hard sandstone
- Quartz-rich formations
- Limestone
- Dolomite
- Granite
- Basalt
- Interbedded formations
- Abrasive and fractured rock layers

Its conical geometry allows efficient rock crushing and fracture initiation, making it particularly effective in medium-hard to extremely hard formations.
Core Product Advantages
Superior Compressive Strength
The optimized conical structure effectively distributes drilling loads, allowing the cutter to withstand extremely high compressive forces during aggressive drilling operations.
Outstanding Impact Resistance
Designed for challenging formations, the reinforced diamond-carbide interface minimizes chipping and cracking caused by repeated impacts.
Excellent Wear Resistance
Premium polycrystalline diamond layers provide exceptional abrasion resistance, significantly extending service life in abrasive formations.
High Thermal Stability
The advanced manufacturing process improves thermal resistance, maintaining cutting performance under elevated drilling temperatures.
Faster Penetration Rate
The pointed conical profile concentrates energy at the contact point, enhancing rock-breaking efficiency and increasing rate of penetration (ROP).
Longer Bit Service Life
Reduced cutter wear and improved durability help decrease bit replacement frequency and lower overall drilling costs.
Precise Size Specifications
The C0609 Conical PDC Cutter features a nominal diameter of approximately 6.4 mm and an overall height of approximately 9.3 mm. Its compact dimensions make it suitable for precision cutter placement in roller cone bits, directional drilling tools, mining bits, and specialized hard rock drilling applications. Custom dimensional tolerances are available upon request for specific drilling programs.
Material and Core Technology
Premium Polycrystalline Diamond Layer
Manufactured using high-purity synthetic diamond particles sintered under ultra-high pressure and temperature conditions for maximum wear resistance.
High-Strength Tungsten Carbide Substrate
The carbide base provides outstanding toughness and structural support, ensuring reliable performance under heavy drilling loads.
Optimized Diamond-Carbide Bonding Technology
Advanced interface engineering improves adhesion strength and reduces the risk of delamination during prolonged drilling operations.
Application Field
Oil & Gas Drilling
Suitable for shallow to medium-deep well operations on land. Works well in tight sandstone, interbedded strata and gravel-bearing formations. High temperature resistance avoids carbonization and delamination, reducing bit replacement and overall drilling cost.
Mining Drilling & Exploration
Ideal for mineral prospecting, tunnel drilling and mine water well projects. Perfect for high-abrasive hard rock such as granite and quartzite. Excellent impact resistance prevents edge chipping, serving longer life in fractured mining formations.
Geological Exploration & Sampling
High dimensional accuracy ensures stable drilling and regular borehole. Guarantees complete formation core sampling, fully meeting high-precision geological survey and resource exploration requirements.
Water Well & Infrastructure Engineering
Widely used in deep water wells, pile foundation drilling and construction projects. Efficient penetration in common rock layers, low wear and stable performance for long-time continuous site operation.
Universal Bit Matching
Compatible with mainstream PDC bits, core bits and drilling tools with good interchangeability. Custom sizes and chamfers are available to meet non-standard matching demands for different projects.
