The INGCO CIWLI20401 1/2" Lithium-Ion Cordless Impact Wrench is a reliable and budget-friendly solution for medium-duty fastening and loosening tasks. With a powerful 20V brushless motor, this tool delivers a maximum fastening torque of 400Nm and a nut-busting torque of up to 550Nm—more than enough for automotive repairs, equipment maintenance, and assembly work. It features a variable no-load speed range (1600/1900/2300 RPM) and a corresponding impact rate (up to 2900 BPM) to accommodate different job requirements. The 1/2" square drive ensures compatibility with standard sockets, and the integrated LED work light enhances visibility in low-light environments. This model includes three commonly used sockets (17mm, 19mm, 21mm) and is packed in a durable color box. Battery and charger are sold separately, making it an excellent value option for users who already own compatible INGCO 20V battery systems.
