Impact Wrenches(Two-Hammer)

Two-hand impact wrenches deliver two strikes per revolution, making them highly efficient and smooth to tighten and remove, and are the most commonly used wrenches in all industries.

Two-hand impact wrenches for standard bolt diameters up to 16mm (NW-14H) are small, lightweight, and have significantly improved start-up capabilities, making them very easy to use and suitable for production lines.

Two-hand impact wrenches for standard bolt diameters of 18mm or more are long-lasting, high-performance impact wrenches that are particularly suitable for removing and installing bolts for secondary concrete product forms.

The NW-16HSA, NW-19AA, and NW-22AA are also environmentally friendly, low-vibration two-hand impact wrenches. There is also the environmentally friendly, low-noise, rear exhaust two-hand impact wrench, the NW-1600SA.
