Atlas Copco QMR55-15ROT Cordless Nutrunner Tool

The Atlas Copco QMR55-15ROT Cordless Nutrunner Tool is a compact, battery-powered bolt-tightening device with a 1/2" drive for standard sockets, designed to handle repetitive tightening on mid-size industrial assembly lines. Because it operates without an air supply, the tool offers mobility on crowded factory floors, service bays, and remote work sites where air lines and compressors would slow progress or create clutter. The QMR55-15ROT accepts common 1/2" drive sockets, enabling technicians to reuse existing tool kits while maintaining consistent engagement across bolting tasks in line with Atlas Copco’s approach to controlled tightening. Typical applications include manufacturing assembly, equipment installation, and preventive maintenance in industrial environments where portable, reliable bolt tightening is essential to keep production lines running smoothly and equipment serviced.
