Supplied in a robust plastic case, this set includes an industrial quality chrome molybdenum impact driver with switchable forward and reverse screwdriver rotation. When the impact resistant handle is struck with a hammer, the downward force is converted by the impact driver's internal mechanism into a powerful high torque screwdriver rotation action.
