20V Brushless Impact Screwdriver with 130N.m Torque & Stepless Speed Control
PRODUCT DESCRIPTION
Advanced Brushless Motor & High-Torque Performance
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.
Intelligent Control & User-Centric Functionality
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.
Ergonomic Design & Enhanced Usability
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.
Professional-Grade Construction for Diverse Applications
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.
