The 1/2” impact wrench with jumbo single hammer system is a compact, powerful, and highly efficient pneumatic tool, designed to meet the needs of professionals, technicians, and skilled workers who require high performance and reliability in daily fastening and loosening operations. With a length of only 104 mm and a weight of 1.37 kg, it stands out for its maneuverability and ability to work in confined spaces without compromising power or durability. The integrated air exhaust through the handle improves operator comfort by diverting airflow away from the work area, while the three-position forward/reverse regulator ensures quick, precise, and intuitive control of tightening and loosening cycles. An additional technical advantage is the dedicated lubrication port built directly into the shaft, allowing easy and fast maintenance, constant greasing of internal mechanisms, and significantly extending the tool’s service life.

At the core of its performance is the jumbo single hammer system, a mechanism designed to maximize concentrated impact force. In this configuration, a large hammer accumulates rotational energy and transfers it in one strong and direct blow to the output shaft. Compared to other impact systems, the jumbo single hammer prioritizes immediate force and consistent impact, minimizing energy loss and ensuring maximum torque delivery in the shortest possible time. This technology not only guarantees outstanding power but also simplifies the internal structure, with fewer moving parts subject to wear, resulting in lower maintenance requirements and higher reliability.

Features:

From a performance perspective, the tool delivers a maximum torque of 949 Nm, with an adjustable range between 244 and 542 Nm, making it suitable both for controlled tightening of sensitive components and for demanding loosening operations on bolts up to 20 mm. The free speed reaches 10,000 rpm, enabling quick work cycles and high productivity. The tool operates with compressed air at a recommended pressure of 6.2 bar, using a 1/4” BSPT air inlet and a 10 mm internal diameter hose, while its average air consumption of 2.3 liters per second ensures efficiency and continuous operation.

In terms of ergonomics and safety, the impact wrench is designed to offer comfort and performance: vibrations of 7.2 m/s² require mindful use but remain proportional to the power delivered, while the sound pressure level of 94.3 dB(A) and sound power level of 105.3 dB(A) make the use of appropriate personal protective equipment, such as hearing protection, essential.

This impact wrench is suitable for a wide range of applications: from mechanical and metalworking industries to automotive repair, from maintenance workshops to production plants, and up to the assembly and servicing of complex machinery. The combination of extreme compactness, high torque output, simple maintenance, and the reliability of the jumbo single hammer system makes it an indispensable tool for professionals seeking precision, durability, and speed in fastening and disassembly operations.
