Techno 1/2 Inch 12.7mm Twin Hammer Impact Wrench AT243 | 850Nm High-Torque Pneumatic Air Impact Gun with 8000 RPM, 6.3 Bar Working Pressure for Automotive, Heavy Machinery, Garage, Workshop & Industrial Applications
The Techno AT243 is a professional 1/2-inch pneumatic impact wrench designed for high-torque fastening and loosening applications. It features a 12.7mm (1/2-inch) square drive, twin-hammer impact mechanism, 8000 RPM free speed and a published maximum torque of 850Nm. Techno's price list identifies the AT243 as a 1/2-inch twin-hammer impact wrench with 8000 RPM, while current product listings specify the 850Nm torque rating.
The tool operates using compressed air at approximately 6.3 bar (90 PSI) and has an air consumption of around 8 CFM. Its pneumatic impact mechanism delivers repeated hammering force to the drive spindle, allowing the operator to loosen stubborn, seized or over-tightened fasteners more effectively than a conventional hand wrench.
The twin-hammer mechanism is particularly useful for repetitive automotive and industrial fastening work. The AT243 combines a robust composite and alloy-steel construction with a relatively compact handheld design, making it suitable for professional garages, workshops, machinery maintenance and heavy-duty mechanical applications.
