Applicable Strata
The CB1319 is designed to perform efficiently in:
- Hard and ultra-hard rock formations
- Abrasive sandstone formations
- Granite and quartz-rich formations
- Limestone and dolomite formations
- Mining and quarry drilling environments
- Water well and geothermal drilling projects
- Coal mining and tunneling applications
Its dome geometry helps distribute impact loads evenly, making it particularly suitable for formations where conventional cutters experience chipping or premature failure.
Core Product Advantages
Exceptional Compressive Strength
The dome-shaped structure effectively disperses drilling loads across the cutter surface, allowing the CB1319 to withstand extreme compressive forces encountered in hard-rock drilling.
Superior Impact Resistance
Designed for high-impact drilling environments, the rounded cutting profile minimizes stress concentration and significantly reduces the risk of edge breakage.
Outstanding Wear Resistance
The premium polycrystalline diamond layer provides excellent abrasion resistance, maintaining cutter integrity even after extended drilling operations.
High Thermal Stability
Advanced manufacturing technology enables the cutter to maintain stable performance under elevated drilling temperatures, reducing thermal degradation.
Extended Service Life
Longer wear life translates into fewer bit replacements, reduced downtime, and lower overall drilling costs.
Increased Drilling Efficiency
The optimized dome profile improves rock-crushing efficiency and helps achieve faster penetration rates in challenging formations.
Precise Size Specifications
CB1319 features a compact yet highly durable design with a diameter of 13.44 mm, an overall height of 19.05 mm, a dome radius of 2 mm, and an exposed height of 6.5 mm. These dimensions provide an excellent balance between impact resistance and rock-breaking capability, making the cutter suitable for various drilling tool configurations.
Material and Core Technology
Manufactured using high-quality polycrystalline diamond materials that provide exceptional hardness and wear resistance.
The diamond layer is bonded to a cemented carbide substrate under extreme pressure and temperature, ensuring superior bond strength and reliability.
The engineered dome profile enhances load distribution, reduces localized stress, and improves cutter survival rates in impact-intensive 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.
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.
