DE2534 Diamond taper compound tooth
Video
DE2534 is a 25.4mm diameter premium diamond taper compound tooth, engineered with a conical-spherical hybrid design that merges the high rock-breaking efficiency of conical teeth and the superior impact resistance of spherical teeth. Sintered via advanced HPHT (High Pressure High Temperature) technology, it features a 5mm thick diamond layer, 12mm chamfer, and 34.0mm total height. As a high-end mining-grade cutter, it delivers 5–10× longer service life than traditional tungsten carbide teeth, ideal for extreme wear and impact environments in mining, coal extraction, and rotary drilling.

Applicable Strata
- Medium-hard to hard formations: compact sandstone, limestone, granite, basalt (compressive strength 80–200 MPa)
- Highly abrasive formations: quartz-rich strata, gravel layers, fractured hard rock
- Complex mining formations: coal seams with hard inclusions, metal ore veins, tunnel excavation strata
Core Product Advantages
Hybrid Conical-Spherical Design
Combines conical sharpness for efficient rock penetration and spherical roundness for impact dispersion, outperforming single-shape cutters in complex strata.
Ultra-High Wear Resistance
Diamond layer hardness reaches HV 10,000+, with wear resistance 5–10× higher than traditional carbide teeth, drastically reducing replacement frequency.
Superior Impact Toughness
Reinforced tungsten carbide substrate absorbs extreme impact loads; the tapered structure disperses stress, resisting chipping/fracture in high-vibration mining environments.
Efficient Rock-Breaking Performance
Optimized taper angle concentrates cutting force, improving penetration rate by 25–35% in hard/abrasive rock and shortening construction cycles.
Heavy-Duty Structural Stability
Robust 25.4mm diameter and 34mm height design supports high axial loads, avoiding deformation under long-term heavy-duty operation.
Significant Cost Savings
Long service life and minimal downtime reduce overall project costs by 40–60% in mining and excavation projects.
Precise Size Specifications
DE2534 features standard specifications of 25.400mm diameter, 34.000mm total height, 5mm diamond layer thickness, and 12mm diamond chamfer. A variant model DE2534A is also available, with a 25.350mm diameter, 34.000mm total height, 9.50mm diamond layer, and 8.9mm chamfer for enhanced wear resistance. All dimensions are precision-machined with tight tolerances (±0.05mm for diameter, ±0.1mm for height), ensuring perfect compatibility with high-end mining picks, coal picks, and rotary digging picks.
Material and Core Technology
Diamond layer uses 99.9% high-purity micron synthetic diamond powder with uniform particle size; substrate adopts ultra-fine grain WC-Co carbide (optimized cobalt content) for balanced hardness and impact toughness.
Sintered at 1500°C, 5.5GPa ultra-high pressure to form a seamless metallurgical bond between diamond and carbide, eliminating delamination risks and ensuring structural integrity under extreme conditions.
CNC-machined tapered-spherical profile with laser-finished chamfer; low-residual-stress treatment enhances thermal stability, resisting graphitization at high temperatures during continuous drilling.
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 (25.0–25.5mm), total height (32–36mm), diamond layer (4–10mm), and chamfer (8–15mm)
- Performance Customization：High-wear type (thick diamond layer), impact-resistant type (reinforced substrate), high-temperature type (low residual stress)
- Structural Customization：Modified taper angles, spherical arc optimization, and anti-vibration groove processing
- Service Customization：Provide COC/COA quality certificates, customized packaging, and one-on-one technical support for mining/rotary drilling 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.

FAQ
Q: What makes DE2534 different from traditional tungsten carbide teeth?
A: DE2534 adopts a diamond-carbide composite structure with 5–10× higher wear resistance and better impact resistance. It avoids frequent replacement of carbide teeth, drastically reducing downtime and long-term costs.
Q: What is the difference between DE2534 and DE2534A?
A: DE2534 has a 5mm diamond layer and 12mm chamfer for balanced wear and impact resistance. DE2534A features a 9.5mm thicker diamond layer for enhanced wear resistance, ideal for ultra-high-abrasion formations.
Q: What operating parameters are recommended for DE2534?
A: Optimal parameters: 25–40kN weight per tooth, 60–120RPM rotating speed, and mud flow 25–35L/min for cooling. Increase weight for hard granite; reduce RPM for fractured rock to avoid impact damage.
Q: Can DE2534 work in wet or water-rich mining environments?
A: Yes. The integrated sintered structure has excellent waterproof and anti-corrosion properties, with no delamination or rusting in long-term wet conditions. It maintains stable performance in underground coal mines and water-rich hard rock strata.
