Techgong Spare parts cutting Bit with tungsten carbide for microtunneling machine

Cutting bit is mainly used to break the lower strength and smaller-diameter
cobbles and gravels;(Good cooperation with Cutter Bits is the primary consideration in the
design of Pre-Cutting Bit. Pre-Cutting Bit cuts the soil mass into small pieces or loosens soil
before Cutter Bits cutting in order to create good cutting condition for Cutter Bits. Pre-cutting Bit is half the cutting width of Cutter bit, so the cutting eciency of Pre-cutting Bit is higher.

Ordinary Cutter Bit is soft ground tool, it generally used for loose strata conditions like
silt, ne 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 Head) to do the excavation.
