摘要： A cutting method comprising using a main body in the form of a circular disk and a hard layer provided on one surface of the main body and having a thickness of 0.02 to 0.2 mm. The hard layer is made of cemented carbides, TiC TaC, Cr.sub.2 C.sub.3, Al.sub.2 O.sub.3 or the like, while the main body is made of a material, such as steel, non-ferrous metal or plastics, which is lower than the hard layer in abrasion resistance. The hard layer is formed along its outer periphery with a cutting edge which is self-sharpened when chipped.
