The Milwaukee M18ONEFHIWF12-0 impact wrench is made with sturdy construction, and it weighs around 3kg with the battery on. It is also compact in design, and you would find it comfortable to work with it.

Here, you get a no-load speed of 1750RPM, but that can be reduced if you wish. The tool comes with 4 power/speed modes that range from 550RPM, 1400RPM, 1750RPM, and 1750RPM. This way, you can choose the model that best suits your project needs.

As a result, you get a high fastening torque of 1356Nm, which is better than most models out there. If you will be removing some bolts, the machine offers you a maximum nut-busting torque of 1898Nm. But you can change it to 750rpm when removing the fasteners.

Besides the torque setting being adjustable, you also get an integrated blow counting sensor. This sensor helps to enhance the consistent repeatability of the chosen torque setting. All in all, you will be sure of having a reliable tool at your disposal.
