The blade adopts a diamond particle alloy formula and is fixed on a thickened alloy steel substrate through laser welding technology. It has high hardness and strong wear resis- tance, and can repeatedly cut hard materials such as concrete, cement, and stone. The unique Alternative-direction double/three piece combination structure is to cut into standard groove shapes in one go, with smooth groove walls, reducing the need for later finishing processes and greatly improving construction efficiency. The substrate is equipped with heat dissipation grooves and chip discharge holes, which can effectively cool down and remove slag during dry cutting, reducing the risk of edge breakage and deformation.
