The Astro Tools 1895 Onyx 1/2″ Thor G2 and 1828 Onyx 3/8″ Nano Impact Wrenches combine groundbreaking torque performance with compact engineering. Designed to handle tough mechanical tasks, these tools are suitable for professionals seeking precision and power. This review explores their technical strengths, user suitability, and comparisons within their price segment.
Outstanding Torque and Compact Engineering Deliver Advanced Impact Performance
The Astro Tools 1895 Onyx Thor G2 is marketed as one of the highest performing 1/2″ impact wrenches available. It offers a max torque rating of 1,020 ft-lbs, powered by a larger motor and improved air pathways that enhance airflow efficiency. Despite the increased performance, the tool retains a short length similar to the original model, making it practical for tight spaces.
The accompanying 1828 Onyx 3/8″ Nano Impact Wrench features a max torque of 500 ft-lbs. What stands out is its extremely short profile—less than 3-7/8 inches in length—ideal for precision work in confined areas. It includes 3 forward and 3 reverse speed settings and a twin hammer design, ensuring efficient hammer strikes and smooth operation.
