DW1214 diamond wedge enhanced compact

Short Description:

The company can now produce non-planar composite sheets of different shapes and specifications such as wedge type, triangular cone type (pyramid type), truncated cone type, three-edged Mercedes-Benz type, and flat arc type structure.wedge-shaped diamond composite teeth are stronger in impact resistance and toughness than flat composite teeth, and have sharper cutting edges and lateral impact resistance compared with tapered composite teeth. During the drilling process of the diamond bit, the wedge-shaped diamond composite tooth changes the working mechanism of the planar diamond composite sheet from “scraping” to “plowing”. Cutting teeth advance resistance, and reduce the cutting vibration of the drill bit.

Applicable Strata

The DW1214 is suitable for a wide range of geological formations:

  •  Soft to medium-soft formations
  • Medium-hard shale
  • Sandstone and limestone
  • Interbedded formations
  • Moderately abrasive formations
  • Formations requiring long-lasting cutter performance

Its balanced design allows stable cutting and reduced bit wear across diverse drilling environments.

 

Core Product Advantages

Exceptional Compressive Strength

Designed to withstand high drilling loads without deformation, ensuring reliable operation in deep wells.

Superior Impact Resistance

Reinforced carbide substrate and optimized diamond table absorb shocks, reducing chipping and breakage.

Outstanding Wear Resistance

Premium synthetic diamond layer provides excellent resistance to abrasive formations, extending cutter life.

High-Temperature Stability

Maintains performance under elevated downhole temperatures, minimizing thermal degradation.

Increased Drilling Efficiency

Optimized cutter geometry improves rock penetration, enhancing rate of penetration (ROP).

Longer Bit Service Life

Reduced wear and damage contribute to fewer trips and lower operational costs.

Precise Size Specifications

The DW1214 features a precision-engineered geometry suitable for modern PDC drill bits. Its diameter, overall height, diamond layer thickness, and chamfer configuration are optimized to distribute load evenly, improve cutting stability, and resist wear and impact. This ensures consistent performance in conventional, directional, and horizontal drilling applications.

Material and Core Technology

Premium Polycrystalline Diamond Layer

Ultra-hard synthetic diamond particles sintered under HPHT conditions for superior abrasion resistance.

High-Strength Tungsten Carbide Substrate

Provides toughness and impact resistance to support the diamond table during extreme drilling.

Advanced HPHT Manufacturing Technology

Ensures strong diamond-to-carbide bonding, high consistency, and long-term reliability.

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.

Customer Reviews

Mark Wilson | Oilfield Drilling Project Manager

We have been using their 16mm PDC cutters for a long time. They perform steadily in hard formations with much better wear resistance than other brands. Cutter chipping is greatly reduced, which effectively cuts down our overall drilling cost. Highly reliable for long-term cooperation.

Carlos Rodriguez | Mining Drilling Engineer

Our working conditions are tough with granite and fractured formations. These PDC cutters have excellent impact resistance and longer service life. The dimension accuracy is perfect, fits our drill bits very well without repeated adjustment.

David Brown | Infrastructure & Water Well Contractor

Great customization service for non-standard sizes and special chamfers. Delivery is always on time. The cutters hold up well under continuous high-intensity site operation, fast penetration and low consumption, fully matching our construction schedule.
