    Two materials, cobalt high speed steel (HSS) for the teeth and spring steel as a back material, are joined during the Electron-beam welding process. This welding process results in an optimal combination of material with respect to saw blade resistance to wear and  fatigue.                                                       .
    The material is suitable for producing band saw, hole saw, hack saw, reciprocating saw and some other cutting tools.The cutting tools which is made from bi-metal material are charactered by high productivity, energy saving and so on. It is a wonderful material to reduce power resources and save raw material.
