[0005] Further, eight cutting head seats are provided on the matrix.

[0006] Further, the first chip removal groove is in a thin strip shape.

[0007] Further, the other end of the first chip removal groove extends more than half of the radial width of the cutting tooth.

[0008] Further, the thickness of the cutting tooth is greater than the thickness of the cutting head seat.

[0009] Further, the depth of the first chip removal groove is less than the depth of the second chip removal groove.

[0010] Compared with the prior art, the present application can achieve the following technical effects:

[0011] The utility model is provided with a chip removal groove I and a chip removal groove II on both side surfaces of the cutting teeth. The structures of the chip removal groove I and the chip removal groove II form a plurality of sharp-pointed teeth, which can enhance the tearing force during saw blade cutting. The edges of the chip removal groove I and the chip removal groove II also form cutting edges, making the incision of the object smoother. In addition, the smooth chip removal of the chip removal groove greatly improves the cutting performance of the saw blade.

[0012] Of course, it is not necessary for any product implementing this application to achieve all the above-mentioned technical effects simultaneously. Description of the Drawings
