Description

The DongCheng DCPB488 is a 20V MAX all-copper brushless cordless impact wrench built for professionals who require high-torque fastening and loosening performance across automotive, structural steel, mechanical assembly, and heavy civil construction applications. Powered by DongCheng’s brushless motor platform, the DCPB488 delivers a maximum torque output of 488 N.m — equivalent to 450W AC power — with a nut-busting torque of 682 N.m for breaking loose seized and overtightened fasteners. The all-copper brushless motor runs cooler and more efficiently than brushed alternatives, extending both tool life and battery runtime — a significant advantage in Indian job-site conditions where tools operate through long shifts in heat and dust.

The 3-speed gearbox with three separate torque settings — Low (350 N.m), Middle (400 N.m), and High (488 N.m) — gives the operator precise control over fastening force across different bolt sizes and material combinations. Operating at no-load speeds between 1800 and 2400 RPM with impact frequencies reaching 3500 impacts per minute, the DCPB488 handles M12–M20 standard bolt sizes with speed and accuracy. The smart loosening function is a distinguishing feature, preventing workpieces from falling off during reverse operation — particularly useful in elevated work, underbody vehicle work, and structural bolt removal where dropped fasteners pose a safety and productivity risk.

The compact body design and ergonomic rubber-coated grip keep the tool well-balanced and comfortable during extended use, reducing operator fatigue in repetitive tightening and loosening applications. The built-in LED work light illuminates dark recesses, underbody spaces, and poorly lit panel areas where precise fastener engagement is required. The integrated large-diameter thermovent supports continuous operation under load without heat-related shutdowns, making it suitable for sustained production use. The DCPB488 runs on DongCheng’s 20V MAX battery platform, ensuring cross-compatibility with other tools in the same cordless system.

Features

• All-copper brushless motor delivers 488 N.m maximum torque — equivalent to 450W AC output — with extended motor and battery life
