Norbar EBT – Transducerised Battery Torque Tool

High-accuracy torque control with onboard verification for critical mining and heavy-industry joints.

Heat, repetition and joint variability destroy torque accuracy.

Across mining, rail and heavy industry, technicians face the same problem:

Tools drift as temperatures change on long shifts

  • Fasteners loosen from under-torque or fail from over-torque
  • Current-controlled battery tools give inconsistent results
  • Repetitive tightening leads to accuracy loss and operator fatigue
  • Low-grade tools can’t maintain accuracy in Australian conditions

One inaccurate bolt on a haul truck, dozer frame or underground loader can lead to

downtime, safety incidents, or significant rework costs.

    EBT vs EBT-C: Which Is Right for You?

    EBT – Evotorque Battery Tool

    Best when you need maximum accuracy and advanced tightening modes.

    • Accuracy: ±3% transducer-controlled torque.
    • Torque range: Multiple models from 160 Nm up to 4000 Nm.
    • Tightening modes: Torque, Torque + Angle and Audit modes.
    • Display: OLED screen with multi-mode interface.
    • Data & connectivity: Stores readings, USB and Bluetooth, EvoLog compatible.
    • Gearbox options: Single speed and Auto-Two-Speed models.
    • Size & weight: Full-size industrial housing, heavier than the EBT-C.
    • Ideal applications: General industrial bolting, QA work, angle tightening and high-torque shutdowns.

    Choose the EBT if you need highest accuracy, advanced modes or torque above 1100 Nm.

    EBT-C – Evotorque Battery Tool Compact

    Best when you need a compact, cooler-running tool for repetitive work.

    • Accuracy: ±5% transducer-controlled torque.
    • Torque range: Compact series from 150 Nm to 1100 Nm.
    • Thermal performance: Advanced cooling for continuous-duty, high-heat environments.
    • Tool size: Smaller, lighter design – around 20% more compact than comparable EBT models.
    • Tightening modes: Torque mode only (no angle or audit modes).
    • Display: Simplified top-mounted torque display.
    • Data & connectivity: Not promoted for logging or external connectivity.
    • Ideal applications: Tight access, repetitive or continuous bolting and hot site conditions.

    Choose the EBT-C if compact size, continuous duty and ease of handling matter more than extra modes.

    Frequently Asked Questions

    What applications is the EBT designed for?
    The EBT is suited to critical fastening work in mining, rail, heavy transport and fixed plant environments. It is ideal where joint integrity, verification and traceable torque results are more important than continuous-duty cycle speed.
    What makes the EBT different from standard battery torque tools?
    EBT uses transducer measured torque, intelligent joint sensing and dynamic brake control. This combination delivers real-time feedback, accurate shutdown at the target torque and more consistent results than tools that rely only on motor current, time or speed.
    How is the EBT different from the EBT-C?
    Both tools deliver high performance, but they are tuned for different priorities. The EBT focuses on precision, data capture and audit-ready torque records for critical joints. The EBT-C is optimised for continuous-duty productivity and higher cycle volumes on repetitive tasks.
    Can the EBT export torque data for reporting?
    Yes. The EBT stores up to 3,000 results with time and date stamps and can export data via USB or Bluetooth. Results can be managed in Norbar’s EvoLog software or provided as CSV files for integration with maintenance and quality systems.
    Does the EBT require regular calibration?
    Yes. Like all high-accuracy torque tools, the EBT should be calibrated at intervals that match your site standards and compliance requirements. Norbar Australia and accredited partners provide calibration and service support with fast turnaround.
    Do I need custom reaction arms for my application?
    Standard reaction arms cover many common applications. For tight access, unusual geometries or high-load joints, Norbar can supply custom engineered reactions so the EBT can be used safely and efficiently on specialised mining, rail or plant equipment.
