Material and Core Technology
Core Material
Adopts high-density premium cemented carbide substrate combined with high-purity PCD polycrystalline diamond material. The substrate features high hardness while the diamond layer delivers outstanding wear resistance, improving product durability fundamentally.
Production Process
Adopts industrial-grade high temperature and high pressure (HTHP) integrated sintering technology. The PCD diamond layer is seamlessly fused with the cemented carbide substrate with high bonding strength. It avoids delamination, falling off and tooth detachment during long-term high-pressure drilling, with process stability superior to products made by ordinary bonding technology.
Core Material
All production complies with ISO9001, ISO14001 and ISO45001 international system standards. Three-level inspection is carried out on raw materials, semi-finished products and finished products. All performance indicators including impact toughness, high temperature resistance and wear resistance reach stable standards. Factory direct supply ensures fully controllable quality.
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.

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.
