MUTHEL BM-DH/BM-DHP High-speed Large Screen Torque Wrench-1.8" Smart Screen High-speed Torque Wrench

BM-DH/BM-DHP Brushless Large Screen High-speed Charging Torque Wrench covers 140-4500Nm torque range with 0.75"/1"/1.5" drive heads. It adopts variable-speed clutch planetary gear system, delivering 4-6 times the no-load speed of standard models, inherits all 1.8-inch large screen and wireless IoT functions of BM-D series, supports MES system integration and full-process data traceability, with ±5% torque accuracy and 5.2/8.0/10AH high-capacity air-cooled battery. Ideal for high-volume high-frequency assembly lines such as new energy vehicles, commercial vehicles and construction machinery mass production

  • Industry-leading High-speed System, 4-6X Assembly Efficiency:

    Adopts unique variable-speed clutch planetary gear system (*H high-speed system), delivering 4-6 times the no-load speed of standard BM-D series models, greatly shortening single bolt tightening time.Especially suitable for high-volume, high-frequency assembly lines, significantly improving production efficiency and reducing labor costs.


  • 1.8-inch Large Color Screen + Intuitive Operation:

    1.8-inch high-definition color large screen, real-time display of torque value, speed, working mode, battery level and all parameters, with intuitive and easy-to-understand operation interface.Supports multi-mode adjustment: digital torque adjustment, 1-99 gear adjustment or arbitrary torque setting within the range, with 10 groups of programmable preset torque for one-click switching.


  • Wireless IoT + Full-process Data Traceability:

    Optional Bluetooth/WIFI wireless transmission module and torque gateway system, supporting seamless docking with host computers and MES production management systems to realize real-time upload of tightening data, remote monitoring and batch management.Supports local log and USB log reading (-P models), optional custom export of bolt tightening data formats, meeting the requirements of Industry 4.0 digital production and quality traceability.


  • High-precision Torque Control + Comprehensive Safety Functions:

    Industry-leading accuracy: ±5% overall accuracy, ±2% repeatability.Built-in wrench overheating temperature monitoring, battery power monitoring and compensation, torque overload limit function, effectively protecting equipment and bolts.Supports user authority hierarchical management, buzzer prompt, tightening result simulation judgment follow-up and anti-reaction force arm locking unloading function.


  • High-capacity Air-cooled Battery System, Long Battery Life:

    Provides three high-capacity air-cooled lithium battery options: 5.2Ah, 8.0Ah and 10Ah, with fast charging technology to meet the needs of long-term continuous operation.Battery power compensation technology ensures stable torque output even at low battery levels, guaranteeing consistent tightening quality.
