The 3/8" impact wrench is a high-performance pneumatic tool designed to deliver power, precision, and speed in tightening and loosening operations on small to medium-sized bolts and screws. Its compact structure, with a length of only 139 mm and a weight of 1.35 kg, makes it particularly easy to handle and suitable for use in confined spaces or during prolonged operations without excessive operator fatigue.

At the heart of the tool lies the jumbo single hammer system, which forms the core of the impact mechanism. In this configuration, a single oversized hammer stores kinetic energy during rotation and releases it in one strong, concentrated blow directly to the drive shaft. This design generates very powerful and consistent impacts, transferring high torque in a short time. The advantages of this system include reduced energy dispersion, greater durability of the mechanism thanks to fewer moving parts, faster tightening operations, and compact construction. Compared to twin hammer systems, the jumbo single hammer prioritizes immediate impact force, making it particularly suitable for applications where concentrated power and speed are essential.

Features:

Thanks to this system, the tool reaches a maximum torque of 271 Nm, with an adjustable range from 7 to 120 Nm. This ensures versatile use, from controlled tightening of delicate components to the removal of more resistant bolts. The free speed reaches 10,000 rpm, providing shorter cycle times and high productivity in every application.

The pneumatic supply requires a recommended pressure of 6.2 bar, with a 1/4” BSPT air inlet and a 10 mm internal diameter hose, while the average air consumption is 1.2 liters per second. These specifications guarantee efficiency and continuous operation with low energy demand. The 3/8” square drive allows the use of standard sockets and accessories, ensuring wide compatibility, while the bolt capacity up to 14 mm extends its range of professional applications.

From an ergonomic perspective, the grip is designed to provide a secure and comfortable hold, while vibrations of 6.6 m/s² require attention but remain proportionate to the tool’s power. The sound pressure level of 93 dB(A) and a sound power level of 104 dB(A) reflect the strength of the tool, making the use of appropriate personal protective equipment advisable.

This impact wrench is used in many sectors, including mechanical and metalworking industries, automotive repair, maintenance workshops, production plants, as well as assembly and repair of machinery. Its combination of compact size, jumbo hammer system, adjustable power, and reliability makes it an indispensable tool for professionals, technicians, and skilled workers who need precision, robustness, and speed in daily fastening and disassembly operations.
