Product Description

Bi-metal saw banding uses M*2/M*1 high-speed Cobalt steel as teeth part and special spring steel as the blade body. They are not combined through high-speed electron beam, but firstly heat treat respectively, then weld them together through high-energy, so that the saw would be more wearable, more red hardness and better fatigueresistance than that of the general technology. 1, ground mass is great, special spring steel and M*2/M*1 high-speed Cobalt steel; 2, the two parts of the blade body and the teeths are heat treated respectively; 3, the unfinished teeths are cylinder-shaped,  and welded to the blade body through high-energy; 4, longer life, lower price.
