Cutter Head for ordinary soil

The shapes of the bits and the sizes of the intake of these heads are designed for the heads to perform best considering the features of layers and machines.

when used in viscous soil layers, make the intake wider to prevent congestion
when used in sand layers, weld the plate to restrict the soil intake
Bit with embedded double conical chips



Depending on layers, you can change the bolted restrictive plate
Compared with heads for gravel layers, the length is shortened to prevent inner congestion
For outer circumferential part: Special head bit
For inner part: face bit (bolted)



This unit has a big opening which match the feature of High-density slurry pipe jacking method.
The V-shape spoke is designed for smooth flow of soil
Outer circumferential part: Shell-shape bit, Inner part: special leading bit


The bits are laid out to cut the whole surface of objects of digging.
Multiple arrays of bits are placed at different cutting phases.
Outer circumferential part: Shell-shape bit, Inner part: double edge face bit
