20V Brushless Impact Screwdriver from China Suppliers - 130N.m Torque, Stepless Speed Control, and Factory Quality
At its core, the KIS21802 is driven by a premium all-copper core brushless motor (Model 4810). This technology eliminates carbon brushes, providing higher efficiency, lower energy consumption, superior heat dissipation, and a significantly longer lifespan compared to standard copper-clad aluminum motors. The motor generates a powerful 130N.m of maximum torque and a variable speed of 0–3000 RPM, effortlessly handling heavy-duty screwdriving, bolt fastening, and drilling into tough materials like wood and metal.
This tool offers precise control through multiple systems. The stepless speed trigger allows infinitely variable rotation—press harder for faster speed, lightly for delicate tasks. A dedicated 3-speed gear switch lets users pre-select the optimal power range for different applications. The forward/reverse switch features a unique reverse auto-stop function: when loosening a screw, the motor stops automatically at the last thread, preventing the screw from falling out and getting lost, enhancing workflow efficiency.
Designed for comfort and extended use, the screwdriver features a soft-grip handle to reduce fatigue and improve control. The integrated LED work light brightly illuminates dark workspaces, while a clear power indicator on the battery pack displays remaining charge at a glance. The 1/4" hex quick-release chuck enables fast, secure bit changes without tools. It is compatible with a flexible battery ecosystem (2.0/3.0/4.0Ah), all featuring over-current, over-charge, and temperature protection for safety.
Built with a robust housing, this impact screwdriver is suitable for continuous professional use. Its versatility makes it perfect for a wide array of tasks, including equipment maintenance, furniture installation, DIY projects, and light construction work. The combination of high torque, intelligent control, and durable brushless motor design makes it a reliable and cost-effective solution for tradespeople and serious DIYers.
