PURPOSE:To prevent a saw blade from easily generating cutting flection, by constituting the saw blade arranging its right setting teeth, left setting teeth and straight teeth as one group so that uniform wearing in the tooth point is obtained over the total length of the saw blade. CONSTITUTION:A saw blade 1 is constituted arranging the total of eight teeth of right setting teeth 3R, 7R, 13R, left setting teeth 5L, 11L, 15L and straight teeth 9S, 17S as one group (set). Each tooth is set to a cutting order of the right setting tooth 3R, left setting tooth 5L, right setting tooth 7R, straight tooth 9S, left setting tooth 11L,right setting tooth 13R, left setting tooth 15L and the straight tooth 17S. Accordingly, a laterally uniform condition of tooth point wearing is obtained over the total length of the saw blade 1, and cutting flection is prevented from being easily generated. |
