ABSTRACT:
A sintered body insert for cutting comprises an intermediate layer consisting of at least one of cemented carbide, a ferrous metal and a high melting point metal, and a first layer and a second layer, each consisting of hard sintered bodies containing cubic boron nitride or diamond, which are arranged on opposite sides respectively above and below with the intermediate layer therebetween. The first and second layers are bonded to the intermediate layer by sintering. The is so formed or configured that its front and rear surfaces define cutting faces. All noses and flanks involved in cutting are formed on the first layer and the second layer, while the centers of gravity of the cutting faces and of the overall insert are located at positions on or in the intermediate layer. Further, coating layers consisting of a nitride of an element belonging to the group 4a, 5a or 6a of the periodic table or other components are formed on the surfaces of the cutting faces and the flanks. With this structure, it is possible to provide a sintered body insert for cutting which is prolonged in life and excellent in economy such as the manufacturing cost.
