S1916 Diamond flat composite sheet PDC cutter
Video
The HTHP sintered 1916 PDC cutter is a premium polycrystalline diamond compact manufactured via high‑temperature high‑pressure (HTHP) sintering process. It features a 19.05 mm diameter, 16.31 mm total height, and a 2.3 mm diamond layer, combining the extreme hardness of PCD with the high toughness of tungsten carbide substrate. Engineered for harsh drilling conditions, it delivers high ROP, long service life, and reliable performance in oil/gas, geothermal, and mining applications.

Applicable Strata
- Soft to medium formations: mudstone, sandstone, shale, limestone
- Highly abrasive formations: quartz‑rich sandstone, gravel, interbedded strata
- Medium to hard formations: dolomite, tight sandstone, low‑grade metamorphic rock
- Deep well & high‑temperature environments: deep oil/gas wells, geothermal wells (thermal resistance ≥ 750°C)
Core Product Advantages
Superior Wear Resistance & Longer Life
Sintered at 6 GPa and 1500°C with dense diamond grain bonding; wear resistance 30%+ higher than standard cutters, reducing tripping frequency.
High Impact Resistance & Chipping Resistance
Tungsten carbide substrate + corrugated interface design absorbs shock loads; shear strength ≥ 4000 N, preventing delamination and tooth breakage.
Excellent Thermal Stability for Deep Wells
Deep cobalt‑leaching process enables 750°C heat resistance, suppressing diamond graphitization and ensuring stable performance in deep/high‑temperature wells.
Good Self‑Sharpening & Consistent Drilling Speed
Optimized PCD microstructure maintains a sharp cutting edge during wear; stable ROP without dulling and dragging.
Strong Bonding & Zero Delamination
Metallurgical bonding at the PCD‑WC interface with corrugated design; increased bonding area and reduced residual stress—no delamination or cracking under long‑term high pressure.
Precise Dimensions & High Compatibility
Standard 1916 size: 19.05 × 16.31 mm with tolerance ±0.05 mm; fits most mainstream PDC bits, easy installation and interchangeability.
Precise Size Specifications
Standard 1916 specification: diameter 19.05 ± 0.05 mm, total height 16.31 ± 0.10 mm, diamond layer thickness 2.30 ± 0.20 mm, end radius 0.30 ± 0.10 mm. Custom non‑standard diameter, height, PCD thickness, flat/curved/spherical cutting edges are available for special bit designs.
Material and Core Technology
Surface: high‑purity polycrystalline diamond (PCD), hardness ≥ 8000 HV for rock cutting.
Substrate: ultrafine‑grain tungsten carbide (WC‑Co), hardness ≥ 1600 HV for support and impact resistance.
One‑step forming at 6 GPa ultra‑high pressure and 1500°C high temperature; forms metallurgical bonding between PCD and WC, bonding strength increased by 50%+ compared to bonded types.
Corrugated interface enhances bonding; special acid treatment removes cobalt catalyst, raising thermal stability from 700°C to 750°C and extending life in high‑temperature applications.
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.
Geothermal & Deep Well Drilling
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.
