Why choose it

The MONSTER impact wrench combines a lightweight composite housing with a powerful twin hammer mechanism, delivering exceptional torque while reducing operator fatigue. Its 3-stage torque adjustment for right-hand rotation allows precise control for tightening, while the single left-hand stage ensures rapid loosening. The downward exhaust directs air away from the work area, keeping the workspace cleaner. With a maximum loosening torque of 1690 Nm, it tackles the toughest jobs with ease.

Ideal use cases

• Removing and installing wheel nuts on trucks and buses
• Heavy equipment maintenance and repair
• Industrial assembly lines requiring high torque
• Agricultural machinery servicing
• Any application where stubborn fasteners need breaking loose

Good to know

The tool operates at a standard workshop air pressure of 6.3 bar and requires a minimum hose diameter of 10 mm for optimal performance. The composite housing not only reduces weight but also provides insulation against cold air, making it comfortable to use in colder environments. Regular lubrication of the air motor is recommended to maintain peak performance and extend service life. Always use impact-rated sockets with this wrench to ensure safety and durability.
