NOVELTY - The new type utility claims have one plant composite fretsaw, comprising the wire and combined layer, the combined layer setting on the wire surface, the combined layer comprises forming wire at surface of graphite alkene-resin layer, on the graphene resin layer is embedded with grinding granule. The utility model is new type of the graphene-resin layer with good elongation rate and toughness, the fretsaw can then produce and crack at high cutting speed, high processing pressure or using process, effective prolong the using life of fretsaw. In addition, graphene-resin layer on resin and adding one quantification of graphite, can reduce the friction force when machining, reducing line saw vibration and improve cutting face flatness is the processing object.
