Product Highlights

The Bosch GDS18V-330C 18V Brushless 1/2 In. Mid-Torque Impact Wrench delivers outstanding performance, whether driving lag bolts through heavy lumber, assembling metal structure, or removing stubborn lug nuts. This impact wrench has a 1/2 In. drive with a friction ring and thru-hole for quick socket changes and secure attachment. The brushless motor delivers up to 330 Ft.-Lbs. fastening torque and 590 Ft.-Lbs. breakaway torque while providing long runtime. Modes such as Auto Stop help prevent over driving, which can damage materials and fasteners. Presets for specific bolts, screws and materials can be customized and saved to the tool via the Bosch Toolbox App (connectivity module sold separately). When reversing in bolt mode, Auto Bolt Release senses when the bolt is loosened and stops rotation to help prevent accidental dropping of bolts and nuts during removal. In addition to customizable settings and modes, connectivity (module sold separately), provides tool specific information and feedback. The kit features two CORE18V® 4 Ah Advanced Power Batteries, which deliver 2x the runtime compared to previous generation BAT612 2.0 Ah battery.
