The Bosch GRS18V-330N 18V Brushless 1/2 in. Right Angle Impact Wrench delivers heavy fastening and breakout power in tight, obstructed mechanical spaces. Designed for commercial automotive technicians, heavy equipment mechanics, industrial millwrights, and HVAC installers, this right-angle impact wrench reaches fasteners that are physically inaccessible to conventional pistol-grip impact tools.

Equipped with a high-performance brushless motor, the GRS18V-330N generates 240 ft-lbs of maximum fastening torque and 410 ft-lbs of breakaway torque. The compact right-angle head profile allows operators to work between frame rails, structural steel crossmembers, and tightly spaced mechanical piping without sacrificing torque capacity. A variable-speed paddle trigger provides continuous throttle modulation to start threads smoothly and prevent cross-threading.

The 1/2 in. square drive anvil utilizes a friction ring retention system to provide quick socket changes while maintaining socket retention under sustained vibration. Built with an all-metal impact mechanism housing, the tool withstands tough jobsite drops, fluid exposure, and heavy duty cycles. As part of the Bosch 18V AMPShare platform, it runs on any Bosch 18V lithium-ion battery.
