Shinano Air Impact Wrench, 1 Inch (25.4mm), Made in Japan - SI1876

1" Pneumatic Impact Wrench

The Shinano SI-1876 1-Inch (25.4mm) Impact Wrench combines high-performance Japanese craftsmanship with rugged, industrial-grade mechanics. Engineered specifically for heavy-duty applications, it features an inline D-handle configuration that offers excellent balance and control during vertical or awkward bolting tasks. At its core is a highly durable pinless hammer clutch system that maximizes power transfer while minimizing wear over extended use. The 6-inch extended anvil gives operators the essential reach required for deep-dish commercial truck wheels and recessed machinery fasteners. Built with a convenient three-piece body construction, the tool simplifies field maintenance and component servicing to minimize workshop downtime.

This powerful pneumatic impact wrench is specially designed to handle structural bolts up to 40 mm (1-9/16 in.). It produces a massive maximum torque of 2,300 Nm (1,700 ft-lb) alongside a flexible working torque range of 830 to 2,000 Nm, ensuring enough brute force to easily tackle stubborn, frozen, or rusted nuts. Operating at a free speed of 4,400 RPM and weighing 12.1 kg, it guarantees fast rundown and highly efficient workshop workflows while maintaining stable handling.
