The Bosch GDS18V-230C 18V 3/8 In. Impact Wrench with Friction Ring is a compact powerhouse, with the impressive power-to-size ratio to deliver results in tight spaces. The impact wrench provides 400 Ft.-Lbs. of breakaway torque for bolt-busting performance and 230 Ft.-Lbs. of controlled max fastening torque with just a 5.7 In. head length. It's equipped with three speed/torque settings for more precise user control. Two preset modes, including Auto Bolt Release and Auto Stop, which automatically stops tool rotation when there is a rapid reduction in resistance, help to prevent the dropping of nuts and bolts. The 3/8 In. anvil friction ring allows for quick socket changes, while the belt clip keeps the wrench within arm's reach and the LED light illuminates dimly lit work areas. The kit includes two CORE18V® 4 Ah advanced power batteries for optimal performance and runtime and one standard 18V charger.
