Can show super digging ability when used with 7160mm diameter shield machines
360mm diameter and 195mm length Disc Cutter (DC1730-0)


This product is made from high quality cold-work die "HQ8" steel, which has super hardness and toughness, and is a bite-and-body integrated type. Compared with the ring-change type, it can be used with larger size bearings because it has more inner space. It can be purchased at a lower price than the ring-change type because it consists of smaller number of parts. It performs well in layers which has strong compressive strength making digging pace slower and leading to frequent bearing damages.
