One group of patterns is composed of a plurality of raised edges arranged, and chip removal grooves are formed between two adjacent raised edges. The base material includes two mutually attached base sheets.

[0006] To facilitate the heat dissipation of the saw blade, preferably, a plurality of heat dissipation holes are formed through the outer wall of the base material and are distributed in a polar axis array.

Multiple sound-absorbing slits are provided on the peripheral edges of both sides of the outer wall of the cutting head. The sound-absorbing slits are arranged radially with the inner ring matrix as the center, which can effectively reduce the noise during the operation of the equipment.
