Milwaukee 2864-20 Tool Customization

The 2864-20 comes with Milwaukee One-Key technology. Connect via Bluetooth to your smartphone and the One-Key app lets you customize performance, track location, and otherwise manage your tool.

Milwaukee mentions “Unlimited Tool Customization” with the 3/4-inch impact wrench. They mean that, by using the One-Key app, you can access predetermined configurations for specific fasteners and materials. It lets you have more control over your driver’s output speed and power.

Repeatable Torque Output

Now we get into “holy grail” territory. Milwaukee claims the M18 Fuel 3/4″ High Torque Impact Wrench delivers the most repeatable torque output in the industry. You can target a torque range, and the gun gets you within that range every time. That leaves you in a good spot for finishing with a calibrated torque device. This repeatability drastically reduces the likelihood of significant under or over-torque. That translates into less damage, less rework, and better productivity.

In short, it could save you a lot of time and hassle.

Custom Profiles

The 2864 has an internal memory that supports up to 4 custom profiles that you can access from a button on the tool. In fact, once you’ve set up and saved the profiles from the One-Key app, you don’t need to maintain the connection to your smartphone to access them. Your profiles also save to the cloud so that you can access them anytime.

Tool Tracking

Lastly, One-Key also provides integrated tool tracking. This lets you look up how and where tools are being used across your network of jobs and users. The app tracks all One-Key devices within a 100-ft. range of your phone. The tracking takes place in the body of the tool, rather than in the battery, which keeps your tool trackable even when the battery is depleted or removed. The app automatically keeps records of the last time a tool was within range of the app.
