Longer Service Life: PDC diamond cutters offer unmatched wear resistance, outlasting even the best grade tungsten carbide picks by a large margin.
Maintained Cutting Speed: Sharp diamond edges cut through the material consistently, preventing the drop in penetration rate seen with worn carbide picks.
Reduced Machine Stress: Sharp picks require less force to cut, reducing vibration and stress on your roadhead, continuous mining equipment or drilling machine components.
Significantly Lower Operating Costs: Significantly reduce the costs associated with frequent pick replacement: parts inventory, labor downtime and machine downtime.
Robust Construction: Made from high-quality alloy steel and using a superior vacuum process to ensure the PDC cutters are impact resistant and reliable.
Types of Diamond PDC Pick
PCD Cutting Tools
PCD cutting inserts and tools are engineered for high-speed machining of nonferrous metals and composites. The PCD layer is fused to a carbide base, providing strength and shock resistance, while the diamond surface ensures long-lasting sharpness.
01
PCD Drills
PCD-tipped or solid PCD drills are designed for precision hole-making in abrasive materials. Their ability to retain sharpness over extended drilling cycles makes them ideal for deep-hole and high-throughput applications.
02
PCD Grinding Wheels
These precision wheels use PCD segments or coatings to grind ultra-hard materials like carbide inserts, ceramics, and gemstones. They offer consistent material removal and surface finish with minimal wheel wear.
03
PCD-Tipped Tools
These tools feature PCD tips brazed onto a carbide or steel body, combining durability with cost efficiency. Only the cutting edge is made of PCD, reducing material cost while maintaining performance.
04
Coated PCD Inserts
Advanced PCD inserts with specialized coatings (e.g., diamond-like carbon or nano-layered films) enhance lubricity, reduce built-up edge, and improve surface finish during fine machining operations.
05
Ripping and cutting coal: The cutter's sharpened edges allow it to rip into the coal face and break apart the coal lumpy, which makes it much easier to extract. Because they are designed specifically to penetrate the surface of coal, much less force is required to make the cut. This enables efficient extraction with controlled use of power.
Expelling cut material: The tapered shape of the PDC pick permits expelling of the cut material away from the cutting zone as mining progresses. This clearance helps prevent the cutter from bogging down or becoming obstructed by debris. It also ensures that material making the cut is evacuated so as not to impede vision or hinder further operation.
Maintaining dust control: One important advantage of the PDC Pick is that it helps reduce excessive coal dust emission during extraction. ThePDC Pick, which improves air quality within the mine and lessens respiratory hazards for miners working underground.
Mining uneven surfaces: The geometry and material of the PDC picks enable them to adjust to and maintain a cutting action over irregular coal seams. This adaptability is valuable as it reduces the need for frequent equipment changes when mining varying conditions.
Core Components & Structure of Diamond PDC Pick
Diamond Layer (Table)
Polycrystalline Diamond (PCD) — micron-sized synthetic diamond particles (~0.00004" size) bonded together Provides extreme hardness (~64 GPa) and abrasion resistance; this is the actual cutting edge
Carbide Substrate
Tungsten Carbide (WC) Acts as a tough, impact-resistant base that supports the diamond layer and enables brazing to the steel body
Pick Body (Shank)
High-strength alloy steel (e.g., 42CrMo super high-strength steel) with advanced alloy cladding Delivers shock resistance, structural integrity, and secure mounting to drilling or cutting equipment
Working Principle of Diamond PDC Pick
PDC Pick: Uses a shearing action — the flat, sharp diamond table slices through material like a knife through butter. This produces a clean cut, requires less force, reduces machine vibration, and generates less heat.
Tungsten Carbide Pick / Roller Cone Bit: Uses a crushing or grinding action, which is slower, less efficient, and causes more wear on both the tool and the equipment.
Pressure: 5–7 GPa (over 700,000 psi — equivalent to stacking dozens of cars onto a surface the size of a coin)
Temperature: 1,400°C to 1,600°C
Catalyst: A metal catalyst such as cobalt is often included, which melts and flows into the spaces between diamond particles, bonding them permanently to the tungsten carbide substrate
This process creates an unbreakable bond between the diamond layer and the carbide substrate, ensuring the PDC button can withstand the harsh impact and abrasion encountered during mining, drilling, and road milling operations.
Maintenance
Regular Inspection
Check for chipping, cracking, or delamination of the diamond layer, especially after heavy-duty operations or interrupted cuts.
Cleaning
Remove built-up swarf, resin, or coolant residue using a soft brush or non-abrasive cleaner to maintain cutting efficiency.
Handling
Avoid dropping or impacting the tool edge, as even ultra-hard materials can suffer micro-fractures from physical shock.
Operating Parameters
Always follow the manufacturer’s recommended cutting speeds, feed rates, and depth of cut. Exceeding these can lead to premature wear or thermal damage despite the tool’s robustness.
