Disc cutters for pipe jacking are designed to perform under varying ground conditions, especially in mixed ground and hard formations where stable rock fragmentation is required. 

Compared to standard TBM applications, pipe jacking operations often involve limited space, variable load conditions, and frequent transitions between soil and rock layers. Disc cutter selection therefore focuses on adaptability, durability, and balanced performance.

Product Types

Single Disc Cutters

Single disc cutters are typically applied in general rock and mixed ground conditions where stable penetration and controlled wear are required.

Suitable for medium to hard rock formations

Balanced load distribution under standard working conditions

Efficient cutting performance with predictable wear behavior

Flexible application across different cutterhead positions

Double Disc Cutters

Double disc cutters are designed for higher load conditions and more demanding formations.

Increased load-bearing capacity for harder rock sections

Improved structural stability under variable ground conditions

Reduced stress concentration in mixed ground applications

Enhanced durability for extended operation cycles
