The XJ.523 21V lithium-ion brushless impact wrench is a heavy-duty industrial-grade tool from the Xiaojia brand.
Powered by a high-power brushless motor with a maximum torque of 350N·m and a heavy-duty impact mechanism, it handles high-strength, high-hardness bolting tasks, easily removing even rusted or seized bolts.
One-touch forward/reverse switching, four precise torque settings, anti-slip vibration-damping design, and an intelligent control system that monitors operation status, along with fourfold safety protection, make it a core tool for heavy-duty auto repair and heavy steel structure construction.
