Industrial Grade Cordless Torque Wrench with Brushless Motor

Standard impact wrenches use metal-on-metal contact, causing high noise, vibration, and significant kickback. The SMG-LDY uses a hydraulic oil pulse unit to transmit energy. This results in much higher torque precision, lower noise, and zero reaction force to the operator's wrist.

Thanks to the integrated electronic transducer, the LDY series achieves a repeatable torque accuracy of +-8%. It is designed for high-precision assembly lines where tightening quality is critical.

Our advanced sealing system and specialized industrial pulse oil ensure long-term stability. Under normal industrial use (2-shift operation), we recommend checking the pulse oil levels every 100,000 to 200,000 cycles to maintain peak performance.

Yes. The LDY series is equipped with a high-performance Brushless Motor. Without carbon brushes to replace, the motor life is extended by 300%, and the tool runs cooler and more efficiently.

For the LDY series, torque can be adjusted via the digital control panel or an external programmer (depending on the specific model). Once set, the tool features an Auto-Shut Off function that stops the motor immediately upon reaching the target torque.
