    A:  I don't own one of these but because it's the switch style instead of the paddle style I would say it's not variable speed.

      A:  I just bought the paddle style and it is variable speed. 5 speeds

          Excellent grinder, does not bog
          I have 2 other, smaller M12 die grinders that I normally use when space is at a premium. For bigger jobs - like when dealing with thick metal or welds - I lug out the M18! It does not bog down like the smaller die grinders and maintains speed even when working on steel using carbide bits. The braking feature is pretty good, however it doesn't stop rotation instantly though - it takes about a second for the bit to come to a complete stop. Still pretty good though. Ergonomically it's pretty comfortable to use, even with gloves. The grinder is pretty well balanced during use and both my hands fit on it just fine. No comment on battery life, though I have used some of the smaller M18 packs for several minutes and they've held up just fine. If I had to pick a negative it's that the button for the locking mechanism is a bit too inset. Would be nice if it stuck out just a few more millimeters which would make it easier to manipulate with gloves on.

          A bit weighty, but excellent.
          I needed a die grinder to wallow out gate hinge holes for larger replacement bolts. The only die grinder I had is air powered and I could not get to my project. This M18 battery powered Milwaukee did the trick. I like not being tethered to an air line or an extension cord. It means I can now grab it and go to a job with no extra hoses or cords. Noise wise, it sounds like my air grinder but noticeably quieter. Obviously the noise level is going to change when under load and depending on what material you are working with. I wear a men’s large glove and this fits my hand well. It is too big for my wife’s size small hands to hold one handed with secure control. The slide switch is easily reached and controlled with just my thumb. The tool is quite nose heavy without a battery. I used a XC 5.0 and it moved the center of gravity back to the handle. It was quite balanced in my hand, but also fairly heavy. The nose is rubberized like the handle, and it is large enough to grab and use for extra control, while keeping my hand safely back from the area being worked. With the battery on the back, this will not stand on end. I personally would never set it that way anyway. It is 15 1/2” long without a battery, so I’d be begging to knock it over. It has an 11/16” collet wrench with it. The lock button is well located and large enough to use comfortably. It would be nice if there was on tool storage for the wrench. I feel like it is going to be easy to misplace. Power wise, it worked just as well as my air driven one. This is far more convenient. Since it is part of the M18 lineup, I have backup batteries if I need them to complete a project. And it is brushless, so it should have extra run time over a brushed die grinder. Overall I am very happy with it.

          Great portable die grinder
          I have lots of uses for a die grinder. I have used a pneumatic grinder for years. the problem with the pneumatic one is that large air compressor. That is fine if I am working in my shop but it means that I have to bring everything I am working on into the shop. That is not always easy. In addition you have to contend with an air hose which can get in the way. This grinder seems to be at least as powerful as the pneumatic one and is completely portable. I was pleased that it was offered as a "tool only" buy since I already have a bunch of Milwaukee M18 batteries. It is described as a tool that brakes as soon as you turn it off. It does stop quickly but I don't think it is any quicker than my pneumatic die grinder. All and all this is a very nice addition to my shop full of Milwaukee M18 tools.
