90° Angled Design for Confined Spaces：

The right-angle elbow structure allows easy access to narrow and recessed areas such as engine compartments, precision equipment interiors and compact mechanical assemblies, making it ideal for automotive repair, electronics manufacturing and small machinery assembly.

Hydraulic Pulse Principle for Precision Torque Control

Driven by hydraulic pulse technology, the wrench delivers highly stable and repeatable torque output, effectively preventing over-tightening and under-tightening, and ensuring consistent assembly quality across mass production operations.

Dual Operation Modes for Flexible Selection

Two configurations are available: auto shut-off type (automatically stops when preset torque is reached) for high-precision assembly, and non auto shut-off type for general tightening tasks. The product line covers GWIS/GWI-50R, 60R and 70R models to match different torque requirements.

Lightweight & Ergonomic for Long-Time Operation

The whole tool weighs only 1.2–1.4 kg with a compact body length of 253–272 mm, reducing hand fatigue during prolonged use and ensuring flexible operation in tight working positions.

High Efficiency with Low Noise Performance

With a no-load speed of 4000–4400 rpm, the wrench ensures high working efficiency. The noise level is controlled between 76.5–85 dB, improving the working environment for operators.

Industrial-Grade Durability & Low Air Consumption

Built for continuous industrial use, the wrench features wear-resistant components and long service life. With average air consumption of 0.32–0.4 m³/min, it works with standard pneumatic power supplies and maintains low operating costs.
