The Einhell IMPAXXO 18/230 is a cordless 1/2″ impact wrench designed for high-torque tasks around the garage, jobsite, or workshop. With up to 2,036 in-lbs (230 Nm) of torque, it delivers the power needed to break loose stubborn nuts and bolts, including lug nuts, fasteners on machinery, and threaded anchors. As a member of the Power X-Change platform, it runs on the same batteries used across 100+ Einhell tools—making it a smart and modular upgrade for anyone building out a cordless tool system. Driven by a high-efficiency brushless motor, the IMPAXXO 18/230 provides more runtime, higher torque, and reduced wear versus traditional brushed motors. It features a robust 1/2″ square drive for sockets and includes a 1/4″ hex bit adapter, making it equally capable for driving lag bolts or screws when needed. Electronic speed control and up to 3,000 impacts per minute let you dial in performance to match your application, whether working with metal, wood, or automotive fasteners.

Compact, ergonomic, and lightweight at just 2.4 lbs (tool only), this wrench features integrated LED lighting, rubber overmolds for grip and comfort, and a belt clip for convenience during breaks. It’s ideal for automotive techs, mechanics, mobile service crews, and serious DIYers who need cordless flexibility without sacrificing torque. For best results, pair with a 4.0 Ah or larger Einhell Power X-Change battery (sold separately).
