C1420 conical Diamond composite teeth
Video
The C1420 Conical PDC Cutter is a high-performance shaped diamond cutter engineered for demanding drilling applications where superior impact resistance and concentrated cutting force are required. Featuring a conical diamond working surface, this cutter delivers enhanced rock-breaking efficiency, improved load distribution, and exceptional durability in hard and abrasive formations.
Manufactured using advanced HPHT (High Pressure High Temperature) sintering technology, the C1420 combines a premium polycrystalline diamond layer with a high-strength tungsten carbide substrate. Its unique conical geometry reduces stress concentration and improves cutter survivability, making it an ideal choice for high-performance oil & gas drilling, mining, geothermal drilling, and geological exploration.

Applicable Strata
The C1420 Conical PDC Cutter is particularly suitable for:
- Medium-hard formations
- Hard formations
- Abrasive sandstone
- Limestone formations
- Dolomite formations
- Quartz-containing formations
- Interbedded formations
- Highly abrasive drilling environments
The conical profile allows for efficient rock crushing and improved resistance to cutter damage in challenging drilling conditions.
Core Product Advantages
High Compressive Strength
The conical structure efficiently distributes drilling loads, allowing the cutter to withstand extreme compressive forces encountered in deep and hard-rock drilling operations.
Excellent Impact Resistance
Compared with conventional flat PDC cutters, the conical design significantly improves resistance to impact loading, reducing the risk of chipping and fracture.
Superior Wear Resistance
Manufactured with premium-grade polycrystalline diamond materials, the cutter offers exceptional abrasion resistance and extended service life.
Outstanding Thermal Stability
Advanced sintering technology and optimized diamond structure help maintain performance under high-temperature drilling conditions.
Enhanced Rock-Breaking Efficiency
The concentrated cutting point generates higher localized pressure, enabling faster rock penetration and improved drilling efficiency.
Extended Bit Service Life
Reduced cutter damage and slower wear rates contribute to longer bit life and lower operational costs.
Precise Size Specifications
The C1420 Conical PDC Cutter features a nominal diameter of 14 mm and an overall height of 20 mm. The optimized cone geometry is designed to maximize impact resistance while maintaining excellent cutting efficiency. Customized cone angles, diamond layer thicknesses, chamfer configurations, and dimensional specifications are available to meet specific drilling requirements.
Material and Core Technology
Manufactured under ultra-high pressure and temperature conditions, ensuring a strong bond between the diamond table and carbide substrate.
The specially engineered conical profile improves force distribution, reduces stress concentration, and enhances cutter durability in hard formations.
A premium carbide base provides excellent support for the diamond layer, increasing impact resistance and overall structural stability.
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.
