Synthetic diamond technology in drilling
Synthetic diamonds play a critical role in modern drilling. Manufactured under controlled conditions, they offer exceptional hardness, thermal stability, and wear resistance. These properties make them ideal for both rotary and percussive drilling applications.
Rotary drilling with PDC cutters
Polycrystalline Diamond Compact (PDC) cutters are used in rotary drill bits to shear rock through continuous rotation. These cutters are made by sintering synthetic diamond particles into a solid mass, which is then bonded to a tungsten carbide base.
Key Features:
- Shearing action – PDC cutters slice through rock, enabling high penetration rates in softer to medium-hard formations.
- Thermal stability – High-grade synthetic diamond resists heat buildup, reducing cutter wear in deep or high-friction drilling.
- Wear resistance – The diamond layer stays sharp over time, minimising bit changes and improving drilling efficiency.
Typical applications:
- Surface mining (coal, iron ore, bauxite)
- Exploration drilling
- Rotary blasthole drilling in medium formations
Percussion drilling with PCD (DEC) cutters
Key Features:
- Impact resistance – DEC cutters combine diamond hardness with carbide toughness for high-energy percussive environments.
- Fracture control – The diamond layer is designed to resist chipping and cracking under dynamic loads.
- Extended life – DEC cutters hold up in hard, abrasive formations, reducing tool wear and improving cost-efficiency.
Typical applications:
- Hard rock mining (granite, quartzite, basalt)
- Underground development
- DTH and Top Hammer drilling in abrasive zones
