The invention relates to a circular saw, a band saw and a gang saw for rolling and stamping corrugated teeth, and belongs to a cutting tool. The circular saw, the band saw and the gang saw for rolling and stamping the corrugated teeth are characterized by mainly comprising a non-cutting body and a cutting body which are integrally rolled or stamped, wherein a corrugated cutting body is directly rolled or stamped on the circumferential part or the upper part with section steel of a disc steel plate; the adjacent bevel edges of the corrugated cutting body are intersected at an included angle of30 to 120 degrees, and intersections are uniformly distributed on the non-cutting body in a staggered mode back and forth; or a super-hard material is pressed and embedded in the front and rear surfaces of the cutting body to form a super-hard material layer while the cutting body is formed, and a wear-resistant layer made of a tungsten cobalt alloy, ceramic or plastic is sprayed on the super-hard material layer; or a super-hard material layer made of diamond or cubic boron nitride (CBN) is electroplated or soldered on the front and rear corrugated surfaces of the cutting body. The circular saw, the band saw and the gang saw have low cost, a high cutting speed and long service life, and are suitable for cutting metallic and nonmetallic materials.
