PDC Cutters: High-Performance Polycrystalline Diamond Cutters for Mining, Milling & Drilling
Our PDC cutters (polycrystalline diamond cutters) are engineered to solve the most demanding industrial cutting challenges—from tough coal mining drill bits to precision milling bits for concrete and asphalt. As wear-resistant, impact-resistant PDC cutters, they deliver consistent performance across soft to hard rock cutting, making them a cost-effective solution for road milling, geological exploration, and stone processing. Whether you need high-efficiency drilling tools for mining or durable road milling cutters for pavement projects, our PDC cutters balance long tool life, speed, and reliability.
What Are PDC Cutters?
PDC (Polycrystalline Diamond Compact) cutters are advanced cutting tools made by bonding a layer of synthetic polycrystalline diamond to a tungsten carbide substrate. This unique combination gives our polycrystalline diamond cutters two critical advantages:
- The diamond layer provides extreme hardness and abrasion resistance—essential for cutting through dense stone, concrete, or hard rock in mining.
- The tungsten carbide substrate adds flexibility and impact resistance, preventing breakage during high-speed drilling or heavy-duty road milling.
Unlike traditional carbide cutters, our PDC cutters maintain sharp edges longer, reduce downtime for tool replacements, and lower overall project costs—making them the top choice for high-performance cutting tools in industrial applications.

Key Features & Benefits of Our PDC Cutters
Our high-performance cutting tools are designed to outperform standard cutters in durability, speed, and cost-effectiveness—here’s how:
- Superior Wear & Impact Resistance: The diamond-tungsten carbide bond makes these impact-resistant PDC cutters ideal for harsh environments (e.g., hard rock mining, abrasive concrete milling) — reducing tool breakage by up to 40% compared to carbide cutters.
- Faster Rock Breaking: Optimized for high-efficiency drilling tools, our PDC cutters deliver 25% faster drilling speeds in soft rock and 15% faster speeds in hard rock—cutting project timelines and labor costs.
- Longer Tool Life: On average, our polycrystalline diamond cutters last 2–3x longer than traditional carbide tools. For road milling projects, this means fewer tool changes and uninterrupted operation.
- Cost-Effective Performance: While initial costs are slightly higher than carbide, the extended lifespan and reduced downtime make our PDC cutters 30% more cost-effective over the long term—perfect for budget-conscious mining or construction teams.
- Versatility Across Applications: No need to stock multiple tool types—our cutters adapt seamlessly to soft, medium, and hard rock formations, as well as concrete, asphalt, and stone. This simplifies inventory management for multi-project operations.
Industry-Specific Applications
Our PDC cutters are tailored to solve unique challenges in four core industries:
1. Coal Mining: Durable Drill Bits for Hard Rock
As specialized coal mining drill bits, our 1300–1900 series PDC cutters excel in medium to hard coal seams. Their impact resistance handles sudden rock fractures, while the diamond layer resists wear from coal dust. Customers report 2x longer tool life compared to carbide drill bits, reducing downtime in underground and open-pit mines.
2. Geological Exploration: Precision for Soft & Hard Rock
For geological exploration cutters, our 0808–1608 series delivers consistent core sampling in diverse formations—from soft sandstone to hard granite. The sharp diamond edges ensure clean core samples, while the tungsten substrate withstands repeated drilling impacts. Ideal for mineral exploration and oil/gas well site surveys.
3. Road Milling: Milling Bits for Concrete & Asphalt
Our 1308–1913 series are industry-leading milling bits for concrete and asphalt. Designed for road resurfacing projects, these road milling cutters feature fast rock-breaking speeds (up to 500mm/min) and resistance to asphalt binder buildup. They work seamlessly with all major milling machine brands, reducing project time by 20%.
4. Stone Processing: Heavy-Duty Stone Processing Tools
For stone processing tools, our 1613–1919 series cuts through granite, marble, and limestone with ease. The abrasion-resistant diamond layer maintains sharpness even after hours of continuous cutting, delivering smooth, precise edges for countertops, tiles, and construction stone. Reduces waste by 15% compared to standard cutters.
Frequently Asked Questions (FAQs)
Q1: How long do your PDC cutters last?
Lifespan depends on application and rock hardness:
- Soft rock (coal/sandstone): 80–120 hours of continuous use
- Medium rock (limestone/concrete): 50–80 hours
- Hard rock (granite): 30–50 hours
This is 2–3x longer than traditional carbide cutters.
Q2: What’s the difference between PDC cutters and carbide cutters?
- PDC Cutters: Harder (diamond layer), more wear-resistant, longer lifespan—best for high-volume, long-duration projects (mining, road milling).
- Carbide Cutters: Cheaper upfront, less impact-resistant—only suitable for light-duty, short-duration tasks (small-scale stone cutting).
Q3: Which PDC cutter model is best for asphalt vs. concrete?
- Asphalt: 1308–1608 series (smaller diamond layer, faster cutting speed, resists binder buildup).
- Concrete: 1608–1913 series (thicker diamond layer, higher impact resistance, handles aggregate in concrete).
Q4: Do you offer custom PDC cutter sizes?
Yes! We provide custom models for unique applications (e.g., oversized cutters for large milling machines, specialized shapes for mining drills). Contact our engineering team with your specifications for a quote.
Q5: How do I maintain PDC cutters to extend their life?
- Clean cutters with water after use to remove dust/asphalt buildup.
- Avoid overheating (use water cooling during high-speed drilling).
- Inspect the diamond layer for cracks before each use—replace if damaged.
- Store in a dry, cool place to prevent tungsten substrate corrosion.
