Product Description
DC1826 PDC Dome Cutter for Maximum Stability and Service Life
The DC1826 PDC Dome Cutter is designed for high-performance drilling tools operating under continuous impact loading. Manufactured using advanced HPHT technology, it combines a premium polycrystalline diamond layer with a high-strength tungsten carbide substrate to deliver excellent wear resistance, impact toughness, and dimensional stability.
Compared with the DC1823, the DC1826 features a greater overall height of 26.0 mm, providing additional support inside the drill bit body. This deeper installation helps improve structural stability and cutter retention during prolonged drilling operations.
The 18.15 mm diameter and 9.93 mm spherical radius allow the cutter to maintain excellent rock-breaking efficiency while minimizing localized stress on the diamond layer.
Applications
The DC1826 is suitable for:
- Heavy-duty DTH hammer bits
- Open-pit mining
- Quarry drilling
- Water well drilling
- Geothermal drilling
- Blast hole drilling
- Hard rock exploration
- Construction foundation drilling
The DC1826 is recommended for drill bit manufacturers requiring enhanced cutter stability in:
• Large-diameter DTH drill bits
• High-impact mining tools
• Long-life rock drilling systems
• Heavy-duty quarry drilling equipment
Key Features
- Extra-height design for improved cutter retention
- Premium HPHT polycrystalline diamond layer
- Excellent resistance to impact and abrasion
- Stable cutting performance in hard formations
- Precision-ground dimensions
- Strong carbide substrate
- Uniform dome geometry
- Long operating life
Why Choose Our DC1318 Dome Cutter?
1.Product Advantages
The increased overall height of the DC1826 provides a larger bonding area inside the bit body, improving structural support during high-frequency impact drilling. This design helps reduce the risk of cutter loosening and extends the service life of both the cutter and the drill bit.
Its optimized dome profile evenly distributes impact forces across the PDC layer, maintaining consistent drilling efficiency in abrasive formations.
2.OEM & Custom Manufacturing
We supports complete OEM manufacturing services, including:
• Customized PDC grades
• Diamond table thickness options
• Precision dimensional tolerances
• Edge chamfer modification
• Laser marking
• Private label packaging
• Bulk production
