Bosch GDS18V-221B25 18V Brushless 1/2 Inch Impact Wrench Kit Two CORE18V 4.0Ah Batteries Auto Bolt Release Cordless Fastening Driver

Master High-Torque Fastening and Precision Assembly with Compact Brushless Control

Power through stubborn fasteners, lag screws, and large concrete anchors with the exceptional control of the Bosch GDS18V-221B25 18V EC Brushless 1/2-Inch Impact Wrench Kit. Engineered specifically for professional automotive technicians, steel framing contractors, and industrial assembly crews, this dynamic power tool leverages Bosch’s advanced mechanical hammer-and-anvil impact system. Driven by an ultra-efficient EC Brushless motor, it delivers up to 221 Ft.-Lbs. of maximum fastening torque while offering an impressive no-load speed up to 2,400 RPM and 3,400 IPM. The tool boasts an incredibly short 6.4-inch head length and a bare weight of only 2.77 lbs, making it the premier compact solution for operating effortlessly in engine bays, under vehicle chassis, or in overhead structural framing joints.

This heavy-duty cordless impact wrench kit prioritizes smart jobsite safety and productivity with its integrated Auto Bolt Release (ABR) technology. When activated during disassembly, the sensor system automatically stops tool rotation the exact millisecond torque resistance drops, preventing you from throwing threads or dropping fasteners when backing out nuts. Socket security is unyielding thanks to a specialized 1/2-inch square drive anvil combining a friction ring and a structural thru-hole for fast friction swaps and solid pinning. Bundled with two compact CORE18V® 4.0 Ah high-power lithium-ion batteries and an integrated high-intensity LED work light, this professional package guarantees continuous runtime and crystal-clear targeting visibility on any commercial job.

Specifications

Pro-Tip: The dual-retention system on the GDS18V-221 anvil gives you great jobsite flexibility. For standard mechanical work involving frequent socket swaps, use the outer friction ring for fast snap-on changes. However, when working on high-vibration overhead scaffolding or commercial structural steel joints, always utilize the integrated thru-hole with a locking pin and secure o-ring. This absolute lock stops heavy impact sockets from shaking free and plummeting onto lower levels, ensuring strict jobsite safety compliance.
