DE1319 Diamond taper compound tooth
Video
DE1319 is a high-performance special-shaped diamond taper compound tooth produced by advanced high-pressure high-temperature (HPHT) sintering technology, with the same core production process as diamond composite sheets. It features a pointed-top and thick-bottom tapered structure that delivers exceptional formation-breaking capacity, outstanding impact resistance and ultra-high wear resistance, making it a premium replacement for traditional cemented carbide teeth. With a standard diameter of 12.925mm, total height of 19.000mm, 4.6mm diamond layer and 5.94mm chamfer, it is widely used for road milling machinery and heavy-duty drilling operations.

Applicable Strata
- Road engineering surfaces: asphalt pavement, concrete pavement, hardened road bases
- Medium-hard formations: compact sandstone, limestone, marlstone (60–120MPa compressive strength)
- Highly abrasive formations: quartz-bearing strata, gravel layers, broken rock interbeds
- Mining & engineering strata: coal seams, soft-to-medium hard metal ore formations
- Construction engineering foundations: bridge pile foundations, tunnel excavation strata
Core Product Advantages
Extreme Wear Resistance
Adopts high-density HPHT-sintered diamond layer with hardness up to HV10000+, providing 5–10 times longer service life than traditional cemented carbide teeth and greatly reducing replacement frequency.
Excellent Impact Toughness
The reinforced carbide substrate and tapered structure effectively disperse impact force, remaining crack-free under high-vibration working conditions and lowering equipment damage risk significantly.
High-Efficiency Breaking Performance
The sharp tapered tip reduces contact area and concentrates cutting force, easily crushing hard road surfaces and rock strata to improve operation efficiency by 20–30%.
Stable Structural Strength
Robust tapered body design supports heavy axial loads, avoiding deformation and fracture in long-term heavy-duty road milling and drilling operations.
Perfect Dimensional Compatibility
Precision CNC machining ensures tight dimensional tolerances, with high interchangeability for mainstream road milling cutters, PDC bits and engineering drilling tools.
Remarkable Cost Efficiency
Long service life and less downtime cut overall maintenance and operation costs by 40–60% compared with carbide tooth solutions.
Precise Size Specifications
DE1319 diamond taper compound tooth adopts standard fixed specifications: diameter 12.925mm, total height 19.000mm, diamond layer thickness 4.6mm and diamond layer chamfer 5.94mm. All products are processed with precision machining to ensure strict dimensional consistency, featuring excellent batch stability and perfect compatibility with road milling machinery, mining picks, PDC drill bits and various engineering drilling tools, realizing fast installation and replacement.
Material and Core Technology
The cutting layer adopts 99.9% high-purity micron-grade synthetic diamond powder with high density and uniform particle distribution, delivering a hardness of HV10000+ for exceptional wear resistance. The substrate is made of ultra-fine grain WC‑Co cemented carbide with optimized toughness, providing strong support and excellent shock absorption to resist fracture under heavy impact loads.
Adopting the same high-pressure high‑temperature (HPHT) sintering process as diamond composite sheets, the diamond layer and carbide substrate are fused into a seamless metallurgical bond under high temperature and ultra‑high pressure. This completely eliminates delamination, ensuring stable structural integrity under long‑term high‑wear and high‑vibration working conditions.
The tooth body is formed by CNC precision machining to create a sharp pointed‑top and thick‑bottom tapered profile, with a laser‑finished chamfer to reduce stress concentration. Special low‑residual‑stress treatment is applied to enhance impact toughness and anti‑chipping performance, while the tapered structure greatly improves formation‑breaking efficiency and adaptability to hard abrasive surfaces.
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.
Customized Service
- Dimensional Customization: Adjust diameter, total height, diamond layer thickness and chamfer size to match non-standard tools
- Performance Customization: Thicken diamond layer for high-wear conditions; optimize substrate for higher impact resistance; enhance thermal stability for high-temperature operations
