[0002] Saw blade is the steel strip with tooth blade, and the tooth blade is the main part of the saw blade. The saw blade is welded by two kinds of metals, specifically, is composed of carbon steel saw body and high speed steel saw tooth. It is used for cutting pipe, solid body, wood, plastic and all processable metals. Compared with single metal saw blade, it has higher heat resistance and wear resistance, and longer service life. It has strong flexibility, can effectively avoid fracture and damage in the cutting process.
