Definitions
- the present invention relates to a saw blade, and more particularly, to a bevel formed in a right and left set tooth, which is provided with left and right set teeth, in the form of a crack (repellent) whose tip side gradually expands in the left and right direction.
- a crack repelent
- ⁇ As for the type of assembling, ⁇ , the straightness of the straight line and the right and left out of the tooth as viewed from the cutting direction of the cutting tooth, and the right and left out of the tooth are provided. It has a configuration with left and right projection teeth protruding. Then, in order to cope with vibration, etc. in cutting and holding a single piece, the arrangement pattern of an appropriate number of straight teeth and a plurality of left and right set teeth is changed. Various patterns, such as a set, a web set, a straight set, and the like, and making the pitch of each cutting tooth an unequal picture are performed.
- the bee-shaped set type does not have a set of left and right set teeth with a set of left and right set teeth.
- each cut tooth is provided with a bee-shaped tip whose tip is gradually expanded in the left-right direction.
- This is a configuration in which chips of various shapes and dimensions are provided. For example, it is disclosed in Japanese Patent Application Laid-Open No. Hei 11-191392 and Japanese Patent Application Laid-Open No. 2000-31772.
- the conventional saw blade of the assembling type is shown in Fig. 10 (A) s.
