The utility model discloses a compound tool, this compound tool include the cutter body, and the cutter body includes the necking down section that the axis extends along upper and lower direction, and the lower extreme of necking down section is equipped with anti - boring cutter head, and the external diameter of necking down section is less than the external diameter of anti - boring cutter head, the overhead anti - boring cutter sword that is equipped with the hole boring cutter sword that is used for the boring hole and is used for anti - boring terminal surface of anti - boring cutter, hole boring cutter sword is located anti - boring cutter head periphery, and anti - boring cutter sword is located the inboard of hole boring cutter sword. When compound tool had the casing of hole in processing, the back was accomplished to the hole bore hole of casing to the hole boring cutter sword that utilizes anti - boring cutter head, because the cutter body has a necking down section, after the boring finishes the hole, can make cutter radial movement, utilizes the lower terminal surface of the anti - boring casing of anti - boring cutter sword of anti - boring cutter head. A cutter can be accomplished hole heavy boring, facing (operation), has improved machining efficiency.
