Built on the oil pulse torque principle, it delivers smoother torque output and higher control accuracy than ordinary impact wrenches. It effectively prevents over-tightening, thread stripping and workpiece deformation, ensures torque consistency in batch assembly, and fits precision assembly scenarios with explicit torque accuracy requirements.

It features a standard 1/4"retainer chuck for quick and easy insertion and removal of bits and sockets, with secure locking to prevent accidental drop-out. Compatible with various standard 1/4" hex bits and small-size sockets, it flexibly meets assembly needs for different screws and working conditions, greatly improving changeover efficiency.

Two operating modes are available. The auto shut-off model automatically cuts air supply and stops output when preset torque is reached, ideal for high-precision torque-controlled assembly. The non shut-off model delivers continuous power, suitable for rough tightening and bolt removal. Users can select flexibly based on operational requirements.

It is equipped with multiple patented optimized structures: an oil return valve improves torque accuracy and pressure relief efficiency; a pulse regulator adapts to both soft and hard joint conditions; an X-type seal delivers better sealing performance; reduced-contact blades create less friction and smoother pulse output; a stepless switch enables easier operation. All-round improvements enhance operational stability and service life.

The ergonomic pistol grip fits the palm naturally for comfortable handling and smooth force application, reducing hand fatigue during long continuous operation. The low-noise design runs as low as 74.8 dB (A), effectively improving the workstation environment and meeting the needs of long continuous operation in workshops.
