PURPOSE: A ball wrench is provided to variously use the ball wrench by integrally forming angular wrenches at a head section and a handle section of the ball wrench. CONSTITUTION: A ball wrench(1) has a handle section(6) and a head section(2) formed at an upper portion of the handle section(6). A rachet gear(3) is installed at the head section(2) of the ball wrench(1). Angular wrenches(4,5) having sizes different from each other are formed at upper and lower ends of the rachet gear(3). The angular wrenches(4,5) are welded to the upper and lower ends of the rachet gear(3). The handle section(6) of the ball wrench(1) is formed with an angular wrench(7) having a size different from the sizes of the angular wrenches(4,5) formed at the head section(2) of the ball wrench(1). A screw part is formed at an end of the head section(2) and a screw coupling hole is formed at the angular wrench(7) of the handle section(6). The screw part is screw coupled with the screw coupling hole.
