Atlas Copco has launched the first impact wrench with a closed lubrication system, the LMS 67. By keeping grease inside the tool, it offers low maintenance and exceptional service lifetime. This new generation wrench also provides an impressive power-to-weight ratio.

With the newly developed Grease Retaining System, lubrication is kept inside the tool with the help of a seal that surrounds the impact mechanism. The result, is less maintenance and longer service lifetime, which can be critical on large jobs such as working on trains and large rigs.

The LMS 67 is also a powerful tool – weighing just 9.4 kg it delivers up to 2 800 Nm. The high power comes from a rebound of the clutch and the motor. This rebound will increase with the tightening torque. The tool / the LMS 67 will use this rebound as an extra rotational angel to increase the energy of the next impact. To provide a more reliable wrench, the LMS 67 is powered by a well-proven system that works without springs. This also provides the additional benefit of fewer moving parts when servicing. In addition, the impact mechanism has been balanced to reduce vibrations and increase operator comfort.
