The utility model discloses a bunch-wire-type steel wire capable of driving a cutting fluid. The bunch-wire-type steel wire capable of driving the cutting fluid comprises a plurality of thin steel wires; and the thin steel wires are mutually twisted so as to form a spiral steel wire. The steel wire has the advantages that the cost is reduced, and the steel consumption can be reduced under the same length condition; the capability of driving the cutting fluid is increased, and the tensile force generated by clearances of bunch wires can better drive the cutting fluid and enhance the cutting capability; the utilization ratio of SiC in the cutting fluid is increased, and the effect for enhancing the cutting force is achieved; and SiC aggregation is reduced, and surfaces of silicon chips are prevented from being scratched by large particle aggregated SiC.
