The ONYX 3/8" Reactionless Impact Ratchet Wrench (P/N 1143) from Astro Pneumatic features a unique reactionless impact mechanism, which absorbs kickback and thereby prevents operator’s wrist from fatigue and/or injury.

The “precision forged” ratchet yoke is made of Cr-Mo alloy steel with optimized heat treatment to maintain peak performance and prevent “spreading,” which makes other air ratchets lose power, said the company. The tease throttle provides smooth variable speed control.

Other features include: forward/reverse selector with safety lock to prevent slipping; built-in twin expansion chamber divided by airflow guide fins to reduce exhaust noise; and 360° adjustable exhaust.
