20V Brushless Impact Driver with 280N.m Torque & All-Aluminum Head
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.
