Applicable Strata
DB1824 is engineered to perform efficiently in:
- Medium-hard to hard rock formations
- Abrasive sandstone
- Limestone formations
- Granite and basalt formations
- Coal mining environments
- Quarrying and tunneling projects
- Foundation and geothermal drilling applications
Its spherical profile provides superior load distribution, making it especially effective in highly fractured and impact-intensive formations.
Core Product Advantages
Exceptional Compressive Strength
The reinforced carbide substrate and optimized diamond layer enable DB1824 to withstand extremely high compressive loads encountered during aggressive drilling operations.
Superior Impact Resistance
The hemispherical geometry disperses concentrated impact forces across a larger area, significantly reducing localized stress and minimizing cutter failure.
Outstanding Wear Resistance
The high-quality polycrystalline diamond layer delivers excellent abrasion resistance, ensuring long service life even in highly abrasive formations.
Excellent High-Temperature Stability
Advanced sintering technology provides stable performance under elevated drilling temperatures, reducing thermal degradation during extended operations.
Enhanced Drilling Efficiency
The dome-shaped cutting structure promotes efficient rock crushing and energy transfer, improving penetration rates while reducing operational costs.
Extended Bit Service Life
By combining impact resistance and wear resistance, DB1824 helps extend the overall lifespan of drilling tools, reducing downtime and replacement frequency.
Precise Size Specifications
DB1824 is manufactured with a diameter of 18.0 mm and an overall height of 24.0 mm. The spherical dome features a radius of 9.24 mm and an exposed working height of 7.1 mm, providing an ideal balance between penetration capability, impact absorption, and wear life. This dimensional configuration makes DB1824 suitable for heavy-duty mining bits, roller cone bits, DTH hammers, and specialized drilling tools.
Material and Core Technology
Manufactured using carefully selected diamond powders under ultra-high pressure and high-temperature conditions to ensure superior hardness and wear resistance.
The carbide base offers excellent toughness and support, allowing the composite tooth to withstand severe impact loads during drilling.
Utilizing sophisticated high-pressure, high-temperature sintering processes to achieve strong diamond-carbide bonding, enhancing reliability and service life under extreme working conditions.
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.
