This set includes a 231G air impact wrench and a 170G air ratchet wrench along with a five-piece socket set. The impact wrench’s 6-vane motor yields an optimal power to weight ratio, while the ratchet wrench’s motor delivers 55 foot pounds of torque and 170 rpm of free speed. Both tools sport an ergonomic design for greater comfort. A blow molded storage case makes carrying the set easy.
