DMC Composite Drilling Core Technology

Three core processes build a technical barrier
Systematically address industry pain points: poor wear resistance, weak gauge retention, slow penetration rates, and tendency to slip in traditional drill bits.

Three Core Manufacturing Processes

Every process redefines and surpasses traditional craftsmanship.

Eutectic composite wear-resistant metallurgy

Uniform Crystal Composite Wear-resistant Metallurgy

Precisely controlling crystal growth ensures uniform diamond distribution within the matrix. Combined with composite metallurgy, this creates a gradient wear-resistant structure that equalizes wear rates across all areas of the drill bit's working layer. This prevents premature localized failure and extends overall service life by over 40%.

Technical Advantages

  • Crystal size is controlled at the micrometer level with a uniformity of ≥95%.
  • Gradient wear-resistant structure: surface hardness HRC65+, excellent core toughness
  • Superior self-sharpening performance maintains a sharp cutting edge continuously.
  • Suitable for highly abrasive formations

Concave-dimple drag reduction for efficient rock breaking

Fixed Concave Drag-Reduction Efficient Rock Breaking

Optimized drill bit face geometry and nozzle layout based on rock mechanics and fluid dynamics simulation. The unique concave-curved design reduces drilling resistance by 30% while optimizing the flushing fluid flow to ensure timely cuttings removal, prevent re-crushing, and significantly increase penetration rate.

Technical Advantages

  • Optimized lip face pressure; unit energy consumption reduced by 25%.
  • Multi-gate layout improves slag removal efficiency by 50%
  • Fluid simulation optimization for improved cooling performance
  • Suitable for various complex geological formations

High-temperature and high-pressure sintering

High-Temperature, High-Pressure Integral Sintering

Formed via integral sintering using a 10,000-ton hydraulic press and precision temperature control system at 1000°C+ and 30MPa+ pressure. This process achieves metallurgical bonding between the diamond and matrix, delivering interface strength 2 times higher than traditional methods—ensuring no grain pull-out or tooth breakage even under extreme conditions.

Technical Advantages

  • Sintering temperature accuracy ±5°C, pressure accuracy ±0.5MPa
  • Interfacial bond strength ≥ 800 MPa
  • Relative density ≥99.5%, no porosity defects
  • Designed for demanding conditions such as deep-hole drilling and high-power applications
