The tooth portion 9 is composed of a straight tooth 3, a left tooth 5, and a right tooth 7, and a body portion 11. The left flank tooth 5 projects leftward (leftward in FIG. 4), and the right flank tooth 7 projects rightward. The right corner portion 5a of the left flank tooth 5 is located on the right side (the right side in FIG. 3) of the left corner portion 7a of the right flank tooth 7, and the left corner portion 5b of the left flank tooth 5 is located.
The distance m between the right corner 7b and the right corner 7b in the left-right direction is, for example, about 1.6 times the thickness width (length in the left-right direction) t of the body 11. The thickness of the body 11 is 3
The thickness is almost the same as the width.

A cutting groove W a is formed which has substantially the same distance as the distance between the left corner portion 5b of the left flank tooth 5 and the right corner portion 7b of the right flank tooth 7 in the left-right direction. The cutting groove W a tends to close due to the action of the internal stress of the work material W, and a phenomenon (pinching phenomenon) of pinching the body 11 of the saw blade 1 may occur during the cutting process. Therefore, in order to prevent the constriction phenomenon by increasing the width of the cutting groove W a as compared with the thickness width of the body 11, as shown in FIG. In the left direction), a saw blade 13 has been developed in which the right flaring tooth 5 is largely extruded in the right direction. In addition, in this saw blade 13, between m and t, for example, m =
There is a relationship of 1.9 t, and when cutting is performed with the saw blade 13, the relationship between the position and the roughness on the cut surface of the work material W is as shown in FIG.

There is a saw blade shown in FIGS. 6 and 7 which is not sufficient for preventing the constriction phenomenon and is configured by further protruding the left and right flank teeth 5, 7. The saw blade 15 shown in FIG. 6 has the right and left flanks so that the right corner portion 5b of the left flank tooth 5 and the left corner portion 7b of the right flank tooth 7 are located at substantially the same left-right direction (left-right direction in FIG. 6). Although the teeth 5 and 7 are largely protruded, they are not perfect yet to prevent the constriction phenomenon (note that in the saw blade 15, there is a relationship of m = 2t between m and t).

The left and right right teeth 5, 7 are further protruded so as to be located on the left side (the left side in FIG. 7) of b, and the width of the cutting groove is made sufficiently larger than the thickness width of the body portion 11. While the pinching phenomenon can be prevented as much as possible, the cut surface of the work material W is deteriorated as shown in FIG. 8 and FIG. Then, there was a problem that the machining accuracy of the cutting was deteriorated (for example, in the saw blade 17, m = 2.5 between m and t).
There is a relationship of t).
