The WU389.4 is equipped with a brushless motor, offering higher energy conversion efficiency and longer runtimes, while reducing maintenance needs associated with carbon brush wear. Its three working modes (hammer drill, drill, chisel) allow it to adapt to various tasks, from drilling concrete to metal, and light demolition work. The combination of the separated anti-vibration design and ergonomic handle significantly enhances user experience, maintaining precise control even during high-intensity operations. With an impact energy of up to 2.8 Joules, coupled with a large diameter cylinder, it ensures efficient penetration in hard materials like concrete. The optimal drilling range is 6-16mm, meeting mainstream engineering demands. The safety clutch function automatically disengages power when the chuck is obstructed, protecting the user and the tool from damage.
