Bi-metal bandsaw blades uses M51/M42 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 werable ,more red hardness and better fatigue resistance than that of the general technology.
1.Gound mass is great,special spring steel and M51/M42 high-speed Cobalt steel;
2.The two parts of the blade body and the teeth are heat treated respectively;
3.The unfinished teeth are cylinder-shaped,And welded to the blade body through high-energy;
4.Long life,lower price;
5.Width can be 19mm,27mm,34mm,41mm,54mm,67mm,80mm,100mm,Forward angle can meet customers' such like 0 degree,3 degree ,5,degree ,10 degress and so on.
