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.
