Carbide TBM cutters, also known as tunnel boring picks or cutting teeth, are specialized wear-resistant tools used on Tunnel Boring Machines (TBMs) and pipe jacking machines for underground excavation. These cutters feature a tough steel body and a tungsten carbide tip, designed to break and chip through rock, soil, and mixed ground conditions during tunnel construction.

Key Features:
- Extreme Hardness & Wear Resistance: The tungsten carbide tip ensures long-lasting cutting performance, even in highly abrasive geological formations.
- High Impact Strength: The steel body is heat-treated for excellent toughness, enabling the tool to withstand high loads and continuous vibrations during operation.
- Efficient Rock Breaking: The optimized pick shape and carbide geometry enhance penetration and cutting efficiency, reducing machine wear and energy consumption.
- Secure Mounting: Designed to fit precisely into cutterheads or tool holders for safe, reliable performance in high-pressure environments.
Applications:
- Tunnel Boring Machines (TBMs) for subway, highway, and railway tunnels
- Pipe jacking and micro-tunneling equipment
- Shield machines for soft to medium-hard ground
- Mixed-ground and full-face excavation projects
Advantages:
- Long service life reduces replacement frequency and downtime
- Available in various shapes (conical, flat, wedge) to match ground conditions
- Custom carbide grades and tip designs available for specific geological challenges
- Compatible with major TBM systems and international standards
