Mammut professional impact wrenches are made to deliver superior performance through their improved 3-jaw system and hard-wearing construction and materials.

Weight and power are perfectly balanced in these power tools, letting operators do their work effortlessly and comfortably, also thanks to their reasonably low vibration levels.

Mammut impact wrenches have been engineered for industrial applications such as those found in construction sites, shipyards, railways, infrastructure installation and assembly lines.

And now we can even serve the mining and oil&gas sectors. In fact, our customer needs-oriented approach led us to develop an ATEX I M2-certified series to meet the requirements of industries in these fields.


Mammut professional impact wrenches are designed and built to withstand heavy-duty use in open-air or underground conditions. Our tools are all manufactured locally and we maintain our commitment to quality by individually testing each wrench, for guaranteed safety and efficiency.

Mammut professional impact wrenches are:

  • Ergonomic
  • Compact
