Milwaukee mentions “Unlimited Tool Customization” with the 3/4-inch impact wrench. They mean that the one-key app gives you access to predefined configurations for specific fasteners and materials. This gives you more control over your driver’s output speed and power.

Repeatable torque output

Now we enter the territory of the “Holy Grail”. Milwaukee claims the M18 Fuel 3/4″ High Torque Impact Wrench delivers the most repeatable torque output in the industry. You can target a range of torque, and the gun will put you in that range every time. With that, you’re in a good place to start dealing with a calibrated torque device. This repeatability drastically reduces the likelihood of significant under- or over-torque. That means less damage, less rework and better productivity.
