Shinano Air Impact Wrench, 1/2 Inch (12.7mm), Made in Japan - SI1420T

1/2" Pneumatic Impact Wrench

Manufactured in Japan, the Shinano SI-1420T is a professional-grade 1/2" (12.7mm) impact wrench engineered specifically to handle heavy-duty operations in automotive workshops, commercial tire shops, and industrial assembly lines. Designed to efficiently tackle stubborn, rusted, or over-tightened fasteners, this highly reliable air gun for tires delivers rapid power driven by its advanced twin hammer clutch mechanism. Despite its heavy-duty performance and massive power output, it maintains a surprisingly compact and ergonomically balanced frame, ensuring superior handling during high-volume shift cycles.

At its mechanical core, the tool features a robust 1/2" square anvil that generates an impressive maximum torque of 500 Nm, alongside an adjustable working torque range of 0-400 Nm. Supported by a tough 18 mm bolt capacity and a free speed of 6,000 r.p.m., it guarantees fast and consistent energy transfer. Equipped with a built-in power regulator, an industrial exhaust system, and a two-finger throttle trigger, this heavy-duty air impact wrench provides operators with maximum control, reduced hand strain, and a cleaner, safer workspace.

Key Features & Benefits:

• High-Power 1/2" Drive Size: Engineered with a robust 1/2" square anvil to ensure broad compatibility with industrial impact socket sets and optimized energy transfer.

• Massive 500 Nm Maximum Torque: Delivers heavy-duty breakaway power (369 ft-lb) to easily break loose rusted, cross-threaded, or over-tightened fasteners.

• 18 mm Bolt Capacity: Built with high structural integrity to handle tough, repetitive fastening tasks up to an 11/16" bolt cap capacity.

• Twin Hammer Clutch Mechanism: Delivers rapid, hard-hitting power and exceptionally higher torque with minimal vibration compared to single-hammer models.

• Integrated Reverse Button: Features an accessible directional switch for seamless transitions between tightening and loosening fasteners.

• Built-in Power Regulator: Allows operators to calibrate torque outputs to match the specific requirements of the work surface or bolt size.

• Industrial Exhaust System: Diverts air away from the workspace and operator, ensuring safer, cleaner, and less disruptive operations.

• Two-Finger Throttle Trigger: Ergonomically balanced trigger design offers superior handling control, reducing hand strain during extended shift cycles.

• Heavy-Duty Construction: Engineered with internal alloy steel components to withstand punishing garage environments and dropped impact abuse.
