TBM disc cutters are mounted on the TBM cutterhead in a certain pattern and cover the entire face. They are exposed to different and sometimes even extreme ground conditions during tunneling, so selecting cutters with high quality, reliability and long lifetime is important and critical.

• High qualified sealed parts guarantee bits work well. Close and stable bearing makes bits work well under all execrable environment.

• Advanced and strict techniques as well as scientific assembly make sure to produce highly qualified bits.

• Superior material, reasonable design and improvement in its performance after heat treatment process, all this makes it available in all kinds of tough working conditions.
