Tunnel boring machine cutters referred to as "TBM Cutters", are excavation tools installed on the cutter heads of tunnel boring machines and shield machines, which include TBM disc cutters (single disc cutter, double disc cutter, twin disc cutter) and soft ground cutters (eg. scrapers, cutting knives, buckets, rippers and other cutting tools). This type of disc cutters and soft rock cutters can also be used on pipe jacking machines and other similar equipment.

Litian has been focusing on the development of TBM cutters and solutions suitable for various rock conditions, and we have made remarkable achievements in helping users improve tunneling efficiency and reduce overall costs. Litian has now developed into the largest supplier of TBM disc cutters in China.
