Norbar EBT Battery Torque Multipliers
Norbar EBT Battery Torque Multipliers
Norbar EvoTorque Battery Tools (EBT) are battery-powered torque multipliers that combine a powerful brushless motor with Norbar’s world-renowned gearboxes to deliver fast, reliable, and highly accurate bolt tightening performance.
They feature built-in data memory and transfer capabilities (via USB/Bluetooth) for recording torque results, and intelligent control technology for precision.
The Norbar EBT range spans models from compact to high-torque – covering torque outputs from under 200 N·m up to 4000 N·m – offering a solution for virtually any high-torque application.

Key Features & Benefits
- Fast & Efficient Operation – EBT tools use powerful motors coupled with single-speed or auto two-speed gearboxes for rapid joint completion on high-torque jobs. This means faster bolt rundown and less downtime on repetitive tasks, boosting productivity on the assembly line or in the field.
- Exceptional Accuracy – These tools are transducer-controlled and employ Norbar’s unique Intelligent Joint Sensing (IJS) technology to continually monitor bolt tension. Dynamic braking is applied to prevent overshoot, consistently achieving tightening accuracy up to ±3% of the set torque. You get precise, traceable results every time, even on hard or soft joints, with a clear confirmation when the correct torque is reached.
- Advanced Data Logging & Traceability – The EBT series includes robust data memory that can log 3000+ torque readings (with time/date stamps and user IDs) internally. This data can be downloaded via USB or Bluetooth Low Energy (BLE) to Norbar’s EvoLog software for complete traceability. Such functionality is invaluable in quality-critical industries (like aerospace or energy) where audit trails of torque results are required.
- Portable, Cordless Convenience – As battery-powered torque multipliers, EBT tools are not tethered by power cords or hoses, improving safety and versatility on-site. Each uses an 18V, 5.0 Ah lithium-ion battery that delivers outstanding fastening performance per charge. You can easily bring the EBT to the job (even in remote or confined spaces) – no external pumps or compressors needed – making it ideal for field maintenance and service jobs.
- Safety & Control Features – Norbar EBTs incorporate multiple safety measures. A dual-trigger ‘Safe to Start’ system requires two-button activation, ensuring the operator’s hands are correctly positioned and reducing the chance of sudden movement. A key-lock feature can prevent unauthorised or accidental use of the tool – useful in controlled environments. These tools also produce minimal noise and vibration compared to impact wrenches, improving operator comfort and safety.
- User-Friendly Interface – Every EBT tool has a bright OLED display and intuitive controls for easy setting of torque (and angle, for relevant modes) in any lighting condition. Many models also include an LED work light to illuminate dark workspaces. Users can select different units (N·m, lbf·ft, etc.) and modes (Torque, Torque & Angle, Audit) as needed. An optional ‘Ease-of-Use’ mode (torque-only simplicity) is available to aid simple tasks, minimising setup errors.
- Rugged & Durable Design – Built for industrial use, the EBT range features Norbar’s best-in-class gearbox engineering and a high-performance brushless motor, ensuring long service life even under heavy use. A patent-pending active cooling system keeps the tool temperature down during continuous operations, allowing for extended use without overheating – an advantage over many other battery tools. These tools are also supplied with traceable calibration certificates and are backed by Norbar’s reputable service and support network.
Industries Served & Applications
Norbar EBT battery torque multipliers are trusted across a wide range of industries where controlled high-torque tightening is critical. Key sectors and use cases include:
- Wind Energy – Ideal for assembling and maintaining wind turbines (e.g. tower flange bolts, blade bolts) that require very high torques (often up to 4000 N·m). The portability of the EBT (with no external power source needed) allows technicians to easily perform bolting at height in nacelles or hubs. Accurate, recordable torque ensures turbine bolts are secured to spec, improving reliability of these critical joints.
- Rail & Transportation – The Norbar EBT series is approved by Network Rail in the UK for use on railway infrastructure, underscoring its reliability in safety-critical applications. These tools help rail maintenance crews accurately torque fishplate bolts, track fastenings, and rolling stock components. In heavy vehicle maintenance (truck and bus fleets), EBT multipliers make quick work of lug nuts, suspension bolts, and chassis assembly with precise, repeatable results.
- Aerospace & Manufacturing – In aerospace assembly and MRO, where precision and traceability are paramount, EBT tools provide controlled torque tightening for airframe joints, engine assembly, and ground support equipment. The ±3% accuracy and data logging meet the strict quality standards in aircraft production. Similarly, general manufacturing and assembly lines benefit from the EBT’s speed and consistency for high-torque fastening in products like heavy machinery, agricultural equipment, and structural components.
- Oil & Gas / Power Generation – For oil, gas, and petrochemical facilities, EBT multipliers handle bolting of pipeline flanges, pressure vessels, and valve bonnets with ease. The tools deliver the high torques (1000–4000 N·m) needed for large diameter bolts on refinery equipment and power plant turbines. Their cordless design is advantageous in confined spaces or offshore platforms where pneumatic lines are impractical. Plus, the ability to audit and record bolt torques helps meet regulatory compliance and safety standards in these industries.
- Construction & Heavy Equipment – The EBT-C compact series in particular excels in construction equipment maintenance. Whether working on dozers, excavators, cranes, loaders, or dump trucks, the EBT series applies precise torque to critical bolts (like track pads, blade mounts, and slew ring bolts). The compact, battery-powered design allows service technicians to perform on-site repairs or assembly without hauling around cumbersome hydraulic pumps. Industries like mining, steel fabrication, and bridge construction also rely on EBT tools for assembling heavy structures with large fasteners.
(In addition to the above, Norbar EBT tools find use in sectors such as energy generation, mining & refining, and manufacturing & assembly, wherever controlled torque and portability are required.)
