Bi-metal saw banding uses M42/M51 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 M42/M51 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.
5, Width can be 54mm, 67mm, 80mm, 100mm, 120mm; Forward angle can meet customers, 0° , 3° , 5° , any others.
