At the 2016 Milwaukee New Product Symposium, Milwaukee Tool introduced their new M18 Fuel Sawzall reciprocating saw, model 2721. It’s it has the same specs as their standard M18 Fuel brushless Sawzall, but can be programmed and customized via One-Key.
The M18 Fuel Sawzall with One-Key can be set to operate just like a standard M18 Fuel Sawzall – you don’t need to use the cut optimization options. But according to Milwaukee, if you use the correct One-Key profile for the material you are cutting, you can cut faster and extend the life of your blades.

There are 3 key parameters that can be controlled via the One-Key app.
The first is the trigger ramp-up. This controls how fast the saw goes from a standstill to the cutting speed you’ve selected when you pull the trigger all the way. This allows you to start a cut in a more controlled manner.
For instance, when starting a cut on a harder material, the blade might skate around before it bites. Adjusting the ramp-up setting allows you to start the cut at a slower speed, so it’s easier to keep the moving blade exactly where you want it.
With a standard Fuel Sawzall, or any other traditional reciprocating saw, you would need to feather the trigger to achieve this manually, and would probably still have less control than One-Key gives you.
The second parameter is the cut speed. This allows you to dial in the right speed for the material you are cutting. If you cut through some materials too fast, they’ll heat up the blade and shorten its life. And if you cut too slowly, obviously the cut will take longer and you produce more vibrations, which makes it harder to hold and control the tool.
There was a speed control demonstration that pitted two One-Key Sawzalls against each other, in a contest to see which one would cut through a stainless steel pipe first.
One Sawzall was programmed to behave like a regular Fuel Sawzall, while the second was optimized to cut through stainless steel. I’ve queued up the race in the following video CopTool took at the Symposium.

You should notice two important things: the customized One-Key Sawzall finishes the cut quicker, while the saw programmed to behave like a regular M18 Fuel Sawzall lags behind. Before it can finish the cut, it starts glowing and throwing sparks. Soon the blade is completely ruined.
The third customizable parameter is the cut brake. This feature uses the motor control electronics built into the tool to sense when you break through the cut, and it automatically stops the blade even if you are still squeezing the trigger.
So, rather than having to slow down as you come to the end of a cut, you can cut at full speed all the way through the material without worrying about damaging your surroundings with a moving blade. If you skip to the 9 minutes mark in the above video you can see the brake in action.
You are not on your own in having to figure out the optimum blade ramp-up and speed settings for an application. You can just walk through the settings of the One-Key app. There you can select the material you are cutting, the size of the material, and the kind of blade you are using. The app will even recommend a blade based on the material you are cutting.
You can still set the trigger ramp-up and cut speed manually, if you want.
In the software version I played with, you could also adjust the worklight duration, but I didn’t see an option for brightness or to always keep it on, like I did with a One-Key drill and impact driver to get through a recent power outage, but the final software hasn’t been released yet.
Like all One-Key tools, you can use the app’s tracking function to find your Sawzall, and to lock out tool down so only authorized people can use it.
The new One-Key Sawzall will be available in October 2016 in the following packages:
- Bare tool (2721-20)
- Kit with (2) M18 XC 5.0 batteries, multi-voltage charger, blade, and carrying case (2721-22)
- Kit with (2) M18 High Demand 9.0 batteries, multi-voltage charger, blade, and carrying case (2721-22HD)
We do not have pricing information yet, but based on other One-Key tools it’ll probably cost around $50 more that similar M18 Fuel Sawzall options.
