Astro Pneumatic Tool 1822 ONYX 1/2in Nano Impact Wrench V2 – 500 ft-lb Max Torque

Compact power with serious torque

Meet the Astro ONYX 1822 Nano Impact Wrench, a remarkably small tool that delivers big results. At just 3.85 inches long and weighing 3.0 pounds, it sits comfortably in hand while offering a surprising amount of bite. The v2 upgrade introduces a higher performance motor and a ported exhaust designed to unleash up to 500 ft-lbs of max torque when the job calls for it. This combination makes the 1822 feel agile in tight spaces without sacrificing the tonal punch you expect from a robust impact tool.

Designed as a portable workhorse, the 1822 remains balanced and controllable once connected to an air line. It features three forward and three reverse speeds, giving you flexible control across a range of fastener tasks. The twin hammer design adds durability for repeated use, while the 4.8 CFM air flow supports consistent performance. Hi-Flo fittings are suggested to help maximize efficiency and keep the work area clean and cool during operation.

Why the v2 matters
