No.1 Hardware Industrial & Commercial Supplies Procurement Platform
The WORX WU399.9 26mm Cordless Brushless Rotary Hammer combines high performance with durability, designed for professionals. Its core highlight is the efficient brushless motor, which not only provides excellent power output but also significantly enhances energy conversion efficiency and tool lifespan. With a maximum drilling capacity of 26mm, it is particularly suitable for processing high-hardness building materials like concrete. Coupled with a large-diameter cylinder, it ensures powerful penetration with every impact, greatly reducing work time. The design features a split anti-vibration structure to effectively reduce hand vibration and improve comfort during prolonged use. The fully enclosed circuit board design offers comprehensive dust protection, ensuring the safety and stable operation of electrical components. This rotary hammer also functions as a chisel drill and chisel, expanding its application range and making it an ideal tool for multi-tasking operations, indispensable professional equipment in construction, installation, and maintenance fields.
The brushless motor technology of the WORX WU399.9 Rotary Hammer not only brings higher efficiency and longer battery life but also means less mechanical wear and lower maintenance costs, which is crucial for professional users who rely on their tools for high-intensity work. Its 5 Joules of impact energy, combined with the optimized cylinder design, results in excellent drilling speed, especially when handling larger diameter holes or applications requiring multiple impacts, significantly improving work efficiency. The dual dust-proof chuck and fully enclosed circuit board design together form a robust protective barrier, ensuring stable operation even in dusty or harsh environments. The split anti-vibration structure, from an ergonomic perspective, reduces operator fatigue, allowing them to focus more on precise work. These carefully designed features collectively shape a high-performance, highly reliable, and user-friendly professional-grade rotary hammer.
