    Home products Cutter Bit

    Ordinary Cutter Bit(Tooth Cutter,Scraper Bit) is soft ground tool, it generally used for loose strata conditions like silt, fine silt, clay, medium sand, coarse-grained sand and gravelly sand layers. Cutter Bits are installed on the opening slots of Cutter Head and used for excavating most of the sections. While Shield Machine is moving forward, the Cutter Bit is rotating with Cutter Head. The rotation movement drives cutter edge and tool bit into soil and form axial shearing force( tunnel forward direction) and radial shearing force(tangential direction of Cutter Wheel) to do the excavation.
