20V Brushless Impact Driver 280N.m Torque - Durable All-Aluminum Head from China Suppliers & Factory
Product Description
High-Torque Brushless Motor & Robust Construction
The KIS21803 is powered by a high-performance 4815 brushless motor with an all-copper core, designed for exceptional efficiency, minimal energy loss, and extended service life—far surpassing standard copper-clad aluminum motors. This motor generates an impressive 280N.m of maximum torque, capable of driving large fasteners and handling demanding materials. The tool is further reinforced with an all-aluminum machine head, enhancing heat dissipation, impact resistance, and overall durability for continuous professional use.
Intelligent Control Systems for Precision & Safety
This impact driver offers superior control through multiple integrated systems. The stepless speed trigger provides infinitely variable control from 0 to 2600 RPM, allowing precise application of power. A dedicated forward/reverse switch includes the practical reverse auto-stop function: when loosening a screw, the motor automatically stops as the fastener is released, preventing it from falling out and getting lost, thereby improving workflow efficiency and safety on the job site.
Ergonomic Design & Enhanced Usability Features
Built for user comfort during prolonged operation, the tool features a soft-grip handle to reduce fatigue and improve control. The built-in LED work light illuminates dim workspaces, while a clear power indicator on the battery displays remaining charge. The 1/2" hex quick-release chuck ensures fast, secure bit changes. It operates on a flexible 20V battery platform (2.0/3.0/4.0Ah options), all equipped with comprehensive protection against over-current, over-charge, over-voltage, and overheating.
Professional Application for Demanding Tasks
Engineered for heavy-duty fastening, the KIS21803 is ideal for a wide range of professional scenarios, including construction framing, deck building, machinery maintenance, and heavy furniture assembly. Its high torque and impact mechanism make it suitable for driving long lag bolts, large screws, and performing light-duty drilling into wood and metal. The combination of power, control, and robust build makes it a reliable cornerstone tool for tradespeople.
