DW1318 Wedge PDC Insert
Video
The DW1318 Wedge PDC Insert is a high-performance polycrystalline diamond compact (PDC) cutter engineered for aggressive rock cutting applications. Featuring an innovative wedge-shaped cutting structure, it transforms conventional scraping action into an efficient plowing mechanism, enabling faster penetration into hard formations while reducing drilling torque.
Compared with traditional flat PDC cutters and conical inserts, the DW1318 provides superior impact resistance, sharper cutting edges, improved cuttings evacuation, and enhanced drilling efficiency. It is widely used in oil & gas drill bits, mining bits, geotechnical drilling tools, and other heavy-duty rock excavation equipment.

Applicable Strata
DW1318 Wedge PDC Insert is suitable for:
- Medium-hard to hard sandstone formations
- Limestone formations
- Dolomite formations
- Shale formations
- Abrasive interbedded formations
- Hard fractured rock formations
- Mining and quarry drilling environments
- Oil, gas, geothermal and water well drilling projects
Its wedge-shaped profile allows deeper penetration into hard formations while maintaining stable cutting performance under challenging drilling conditions.
Core Product Advantages
Exceptional Compressive Strength
The optimized wedge geometry effectively distributes drilling loads, allowing the insert to withstand high compressive forces in deep and demanding drilling environments.
Superior Impact Resistance
Compared with conventional flat PDC cutters, DW1318 offers enhanced impact toughness, reducing the risk of edge chipping and cutter failure during aggressive drilling operations.
Outstanding Wear Resistance
Manufactured with premium polycrystalline diamond layers, the cutter maintains sharp cutting edges for longer service life even in highly abrasive formations.
Excellent High-Temperature Stability
Advanced sintering technology ensures reliable performance under elevated drilling temperatures, minimizing thermal degradation and extending operational lifespan.
Faster Penetration Rate
The wedge structure promotes a plowing-style rock-breaking mechanism that increases formation penetration efficiency while lowering energy consumption.
Reduced Drilling Torque
Efficient rock fragmentation and rapid debris removal decrease forward resistance, resulting in smoother drilling and improved bit stability.
Precise Size Specifications
The DW1318 Wedge PDC Insert features a diameter of 13.44 mm and an overall height of 18.00 mm. This optimized geometry provides an ideal balance between aggressive cutting capability and structural durability. The exposed cutting profile is specifically designed to maximize rock penetration while maintaining excellent resistance against impact and abrasive wear.
Material and Core Technology
Manufactured using high-quality synthetic diamond particles, providing ultra-high hardness and exceptional wear resistance.
The diamond layer is permanently bonded to a tungsten carbide substrate through HPHT technology, ensuring superior bonding strength and durability.
The specially designed wedge profile enhances cutting aggressiveness, improves cuttings evacuation efficiency, and reduces drilling resistance during operation.
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.
