I'm blown away by the power this multi-tool has. I have a blue/gray brand corded mult-tool, and I'm always fighting with the cord when I'm working overhead or trying to get into cramped areas. This Milwaukee cordless multi-tool has all the power and better ergonomics without the hassle of a cord. I was also pleasantly surprised at how little vibration is transmitted to my hands.
The tool comes with a sanding attachment and a disc/triangle of 60, 80, 120 (x2), and 220 grit sandpaper. There's also a wood flush cut blade attachment and an adapter that allows you to use just about any other brand's accessories with the multi-tool.
Using a compact M18 battery pack, the tool is about the same weight as the corded multi-tool I also own. This tool has a great balance, and I discovered if my wrist starts to get tired after extended use, I can brace the back end against my forearm, giving me even more control.
With a fresh compact M18 battery, the run time was about 18-20 minutes of continuous operation at full speed while under load the entire time. If you've got a few battery packs and a couple chargers, you should be able to keep going just about indefinitely. I did notice the tool was getting a little warm at the end of 20 minutes, but it wasn't overly hot. Just make sure you don't hold it covering the air vents.
The tool-free accessory change design is awesome. Just flip up the lever and unscrew the tool hold-down (see pictures). There's even a slot in the screw that most accessories will fit in to give you a bit of extra leverage if it gets stuck. Much easier than digging around for an allen wrench to change out accessories. I haven't had an issue so far with the accessories coming loose, unlike other multi-tools I've used.
The speed selection can be varied from 1-12, and there's a separate on/off switch so you can resume at the speed you left off at. The tool stops almost immediately once you turn it off, unlike the random orbital sander I'm used to. It's nice being able to set the tool down immediately when I'm finished sanding.
If you've got a few M18 batteries and chargers already and you're considering a multi-tool, absolutely choose this one. You can't go wrong with Milwaukee, and you definitely won't miss having a cord at all!
