摘要： Provided is a cutting insert which is resistant to breakage and can stably be restrained. A cutting insert configured as a vertically mounted insert has a first rake face adjacent to a first major cutting edge, a second rake face adjacent to a second major cutting edge, a restraint surface located further inward than the first and second rake faces to come into contact with a tool body when a second end surface is used, and a reinforcing portion projecting from the restraint surface. The reinforcing portion has a third projecting ridge provided to extend between the first and second rake faces and halve the restraint surface, a first projecting ridge connected to one end of the third projecting ridge to extend so as to cover at least a portion of a boundary between the first rake face and the restraint surface, and a second projecting ridge connected to another end of the third projecting ridge so as to cover at least a portion of a boundary between the second rake face and the restraint surface.

摘要： A coated cutting tool having a substrate and a coating is provided. The coating includes an inner α-Al2O3-multilayer and an outer α-Al2O3-single-layer. The thickness of the inner α-Al2O3-multilayer is less than or equal to 35% of the sum of the thickness of the inner α-Al2O3-multilayer and the thickness of the outer α-Al2O3-single-layer. The sum of the thickness of the inner α-Al2O3-multilayer and the outer α-Al2O3-single-layer is 2-15 μm. The inner α-Al2O3-multilayer consists of alternating sublayers of α-Al2O3 and sublayers of TiCO, TiCNO, AlTiCO or AlTiCNO. The inner α-Al2O3-multilayer can include at least 5 sublayers of α-Al2O3.
