A cutting assembly for a motor chainsaw has a guide bar with peripheral guide groove and guide surfaces. A saw chain circulates in the guide groove in a longitudinal direction of the guide bar. The saw chain has chain members such as centrally arranged drive members and connectors, laterally connecting the drive members. Some of the connectors and some of the drive members are embodied as cutters arranged alternatingly on opposite sides of the saw chain. Rivets connect the chain members pivotably to one another and extend transversely to the circulating direction. The drive members engage the guide groove and the connectors are slidably supported on the guide surfaces. Each cutter has a base, a support stay connected to the base, and a cutting tooth connected to the support stay. The cutting tooth has a laterally projecting roof portion having a leading end in the circulating direction with a roof cutting edge. The support stay has a first portion positioned in a central plane defined by the drive members, and the roof portion projects in a direction of the cutting plane of the saw chain in which direction the base also faces. The roof portion has an outer angled edge extending in the circulating direction parallel to the base. The angled edge has a lateral cutting edge positioned in front of the roof cutting edge in the circulating direction.
