Generally, when an impact driver or impact wrench offers electronic speed and torque control, the two are tied to each other. The lower the speed, the lower the torque, somewhat proportionally.
Over at the GJ a week or two ago, I read some Milwaukee fans’ concerns that the new One Key brushless impact tools might not offer torque control.
If you recall, tool control is a major feature of Milwaukee One Key. The difference between a One Key impact tool, and non-One Key Milwaukee M18 Fuel Gen2 impact tool, is the ability to customize the One Key tool to your needs and preferences.
Basically, users want to be able to dial in the speed and torque limits for an application, and were worried that One Key might not allow for such independent control.
I checked with Milwaukee, and they said:
You can absolutely adjust the speed and torque individually. See attached screenshot.
So, there you have it.
The new Milwaukee One Key impact driver and impact wrenches are coming out soon.
Are you happy to see that you can set the max torque and speed? And don’t forget that this can be done for all of the 4 separate operation modes.
If you ask me, I think it’s a big deal that you can do this. I’ve heard some complaints and questions over the years, about how and why Milwaukee and other brands set the speed and torque levels for their multi-speed brushless impact tools.
Milwaukee’s M18 Fuel high torque impact wrenches provide a good example of this. The 1/2″ wrench with pin anvil has 350 ft lbs and 600 ft lbs max torque modes, while the 1/2″ wrench with friction ring anvil has 100 ft lbs and 700 ft lbs max torque levels.
Why? Because Milwaukee tailored the settings for their intended user base.
I asked about this a while back, and Milwaukee explained:
1/2″ friction ring users are most commonly in maintenance trades and their most frequent fastening application requiring control is fastening a nug but into a vehicle.
1/2″ pin detent users are most commonly in construction trades and their most common applications requiring control over max torque applied onto a bolt requires anywhere from 240-350 ft-lbs of max fastening torque.
In short, 1/2″ friction inch users require higher high end torque and lower low end torque than 1/2″ pin detent users.
Milwaukee has not discussed plans to release One Key versions of their M18 Fuel high torque impact wrenches. Still, I hope you can see the parallel.
Let’s say you’re in the construction trade, but 350 ft lbs is not low enough for your needs. That’s 4,200 in lbs of torque. Let’s say you want the high torque to function at the 100-150 ft lbs level (1200 – 1800 in lbs) that’s at the higher end of what a typical impact driver can deliver. You can’t mix and match.
But One Key allows you to customize your tool exactly as you like it.
There might still be limitations, but we might have to wait until we have our hands on a One Key impact driver or wrench to find out.
