<p><P>PROBLEM TO BE SOLVED: To provide a saw blade for an electric saw with uneven pitches capable of cutting workpieces such as a pipe, etc., without damaging cutting efficiency and cutting quality. <P>SOLUTION: The saw blade includes straight teeth which are not saw-setting bent and saw-setting teeth which are saw-setting processed to the lateral direction. One saw-setting pattern is composed of a straight tooth, a left saw-setting tooth, a straight tooth, and a right saw-setting tooth (the order of the left/right saw-setting teeth can be reversed). The saw-setting pattern is repeatedly arranged to compose the saw blade. A pitch P4 of the saw-setting teeth (9d, 9e) and a pitch P3 of the straight tooth 9c are set to be uneven, and a pitch P4 and a setting quantity W2 of the left saw-setting tooth 9e and the right saw-setting tooth 9e are all set to be even. The pitch P3 of the straight tooth 9c following the saw-setting teeth (9d, 9e) is set to be smaller, and the pitch P4 of the saw-setting teeth (9d, 9e) following the straight tooth 9c is set to be larger. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
