Product Description
The AWR490D Professional Pistol-Grip Air Impact Wrench is engineered for industrial-grade performance in confined spaces. Despite its compact 240mm length, this heavy-duty pneumatic tool delivers a massive 2000 N.m (1540 ft-lb) of maximum torque, allowing mechanics to tackle high-tension bolts on trucks, buses, and heavy equipment with ease.
Built for versatility, the AWR490D supports both 3/4 inch and 1 inch square drives, providing the flexibility needed for various industrial socket sets. Driven by a high-efficiency air motor reaching 4300 RPM, it ensures rapid fastener removal while the reinforced aluminum alloy housing provides extreme durability against site impacts. With its balanced ergonomic design and multi-step power regulator, this tool is the definitive choice for professionals demanding high power-to-weight ratio in automotive workshops and industrial assembly lines.
