The WORX WU289.2/4 is a 20V cordless brushless impact wrench delivering up to 500 N·m of maximum torque through a 12.7 mm (1/2") square drive, making short work of M10–M16 high-tensile bolts in tyre changing, automotive servicing, machinery maintenance and steel-structure assembly. Its brushless motor and constant-power high-torque control keep torque loss under 8% even as the battery runs low, so output stays consistent through the job. Measuring 140 × 65 × 255 mm and weighing just 1.26 kg as a bare tool, it stays manageable during extended one-handed work. This kit ships with two 20V 5.0Ah lithium-ion batteries and one 6A fast charger, so you can rotate packs and cut charging downtime.
A direct-drive brushless motor produces up to 500 N·m of torque with an impact rate of 2,800/3,200 blows per minute. A high-strength anvil and one-piece insert bushing handle wheel nuts, drive bolts and other high-clamp-load fasteners.
A two-speed selector plus reverse auto-stop gives 0–2,600/3,000 rpm no-load speed, with variable-speed trigger control on top. Reverse auto-stop halts the tool once a bolt breaks free, preventing fasteners from spinning off or backing out too far.
