A twin hammer impact tool is suitable for fastening a screw and comprises a motor, a driving unit connected to the motor, and a hammering unit. The hammering unit comprises a hammer shaft connected tothe driving unit; an inner ring hammer that sleeves the hammer shaft; an outer ring hammer that sleeves the inner ring hammer; an output hammer that can be embedded into the screw; and a plurality ofballs. The inner ring hammer is provided with grooves with openings facing the outer ring hammer. As the hammer shaft rotates, the inner ring hammer reciprocates along the hammer shaft. The outer ring hammer is provided with a plurality of guide grooves corresponding to the grooves. Between each groove and one corresponding guide groove, a ball is arranged. Through the cooperation among the innerring hammer, the outer ring hammer, and the ball, the operation becomes smooth, and vibration is reduced.
