According to the composite diamond saw blade, the diamond composite sheet is arranged on the saw teeth of the saw blade substrate to form the composite diamond saw blade, the angle a can be reduced under the condition that the sharpness of the saw blade is guaranteed (the angle b and the distance c are increased, the contact between the rear corner surface and wood is reduced, and the resistance is reduced) during blade grinding, the wedge angle of the cutting edge of the diamond composite sheet is increased, the impact resistance of the diamond composite sheet is improved, the collapse resistance of the diamond composite sheet is improved, the occurrence of the collapse tooth of the cutting edge of the diamond composite sheet is reduced, the durability of the saw blade is improved, and the use cost of a client is reduced.

As a preferable scheme of the utility model, the center of the saw blade base body is provided with a mounting hole, and a plurality of pin positioning holes are arranged around the mounting hole. During the use through the mounting hole with the saw bit installation on the equipment main shaft, fix a position through the pin locating hole simultaneously, prevent that the saw bit from producing and skidding.

As a preferred scheme of the utility model, a plurality of silencing grooves are arranged on the saw blade matrix and are communicated with the root parts of the grooves between the adjacent sawteeth. Through setting up the amortization groove, can play the amortization effect when using, can also play the effect of heat extraction and prevent that the saw bit base member from warping simultaneously.

As a preferable scheme of the utility model, a plurality of heat dissipation grooves are arranged on the saw blade matrix. Through setting up the radiating groove, can play the heat dissipation in use, fall the effect of making an uproar, and then improve saw bit life.

As the preferable scheme of the utility model, the diamond compact is arranged on the sawteeth through a welding process, so that the diamond compact is stably installed and is not easy to fall off.

In a preferred embodiment of the present invention, the saw blade body is made of alloy steel.

In summary, due to the adoption of the technical scheme, the utility model has the beneficial effects that:
