An indexable cut-off saw is used for cutting metal components, e.g. cutting a bearing cap cluster into separate caps. The saw has a circular tool body for mounting on an arbour and this tool body has flat side faces and a narrow outer periphery. A plurality of circumferentially equally spaced cutting inserts are mounted at the outer periphery of the tool body, these inserts being arranged in groups of three such that the total width of the saw cut is divided between the actions of three cooperating cutting inserts. These three cooperating cutting inserts include a central insert mounted centrally on the outer periphery of the tool body and left and right side inserts mounted in pockets extending into the side faces of the tool body. The left and right side inserts are of rectangular configuration presenting straight cutting edges, while the central cutting insert of each group presents a curving cutting edge. The central cutting insert is preferably in the form of a cylindrical cutter disc with flat side faces providing a cutting edge disposed about the periphery of a side face. Each cylindrical cutter disc is mounted on a side face thereof at an angle within about 1-15° of coincidence with the direction of travel of the insert during cutting. It is also possible to use as the central cutting insert a circular cutting disc mounted axially into a pocket in the periphery of the tool body.
