Shield cutter machine of Tunnelling tool is a kind of advanced
equipment for underground tunnel construction.
This equipment can do the field operation that not affect any
construction on the ground.
This is available and best choice for crowd city areas, protecting
buildings or historic site on the ground.
There have a very big circle blade in the front of shield cutter
machine with carbide shield cutter insert, We have mounting various
kind of cutters on the blade.
In order to promote stable and long life time of application, we
have research and developed carbide shield cutter insert with
special material that mainly suitable for tunnel borer machine:
high impact toughness, high abrasion resistance, stable physical
ability, the appearance of fine workmanship etc.
