Inserts for TBM tools

Tunnel Boring Machine (TBM) carbide inserts are the core rock-breaking components of the TBM cutterhead system, typically embedded as alloy blocks or wear-resistant strips on the edges of disc cutters or scrapers. Manufactured from ultra-high-wear-resistant tungsten-cobalt carbide, they directly withstand intense abrasion and impact from complex geology such as rock layers and gravel during tunneling. Through precisely designed alloy grades, macro and microstructures, they maintain cutting performance under extreme pressure, effectively reducing abnormal tool wear and replacement frequency. This directly ensures tunneling efficiency, controls construction costs, and makes them critical wear-resistant parts that determine the continuity and reliability of tunnel engineering projects.
