FIELD: mechanical engineering; cutting tools. ^ SUBSTANCE: proposed saw blade has carrying part with fasteners and saw teeth in from of projections from at least one side of carrying part. Said projections are provided with cutting edge. Fine-tooth structure on cutting edge is made by cutting of solid material by laser beam directed at acute angle to surface of surface said material. Fine-tooth structure on cutting edge is made curvilinear in height in form of rectangular of triangular projections. ^ EFFECT: simplified manufacture and improved efficiency of cutting tool. ^ 4 cl, 2 dwg |
