Atlas Copco LUM12PR5 Tensor Torque Nutrunner Tool

Atlas Copco LUM12 PR5 is a straight pneumatic screwdriver designed for precision fastening with a maximum torque of 5 Nm, a 1/4-inch hex female output, and a compact 195 mm length that fits into tight assembly spaces. It runs on clean compressed air via a 1/8-inch inlet and a recommended 6 mm hose, with an air consumption of 4.5 L/s and a maximum working pressure of 7 bar, delivering torque reliably up to 450 rpm no-load. The tool weighs about 0.55 kg and measures roughly 34 cm by 10.5 cm by 8.1 cm, offering a lightweight, one-handed-friendly profile. Its shut-off clutch and push-start trigger provide controlled engagement, while a center-to-spindle distance of 20 mm and ISO 28927-2 vibration performance help maintain operator comfort on longer cycles. Sound power is listed at 75 dB(A) (ISO 15744), and the unit carries ISO 11148-6, CE, and EAC certifications, reflecting compliance with European and international standards for assembly tools. This model’s compact profile, standard 1/4" hex output, and robust air-powered performance make it a practical choice for light fastening tasks where precise, repeatable torque is essential.
