If you need a 4.5/5 for size constraints I would go with the 2887 for lock-on, or 2886 for paddle switch. Both of these models are the newer design with the slim head for access in tighter spaces. They also feature the rapid stop brake. If you're okay with a little bit bigger grinder the 2981 and 2980 are capable of utilizing a 6" blade, and have quite a bit more ass behind them. As well as being able to cut deeper. I would not buy the 2880 or 2881 they are a little bit older and don't have the rapid-stop tech. Whatever you do, do not buy a non-fuel model. It is very much worth the extra money for the fuel models on high draw tools. I personally have and use the 2883, great grinder. I prefer the lock-on switch instead of paddle. If the 2887 had been out when I bought mine that's what I would have bought. Answer from TURBOWANDS on reddit.com

There is table further down in this article to compare features which I found helpful in deciding from the many options: https://www.protoolreviews.com/milwaukee-m18-fuel-cordless-angle-grinders/ About to order a 2889-20 for slide switch(locking), braking, and variable speed. One key is not helpful to me personally.

r/MilwaukeeTool on Reddit: How is the M18 fuel angle grinder?
August 27, 2023 -
Looks really bulky and awkward to hold honestly. I’m considering ordering it over buying another cheapo corded one. I’m a DIY weekend warrior not a craftsman. I already have a ton of batteries. Worth it or nah? I see the 2880-20 on Amazon for about 100 bucks.

I love mine. I haven't touched my corded grinder in years.

I have the 5 inch and my only gripe is that there’s no top position for the grip handle. Other than that no issues. Performance is great (I love the rapidstop feature) and as long as you have a few high capacity batteries charged up at any given time you can get through some serious work with it.

Milwaukee Cordless Grinder Review
January 20, 2012 - At the 2011 Milwaukee Tools Symposium in July, I saw a ton of cool tools like their new hand tools and fluorescent bulb tester. Another offering that caught my attention was a 4-1/2' cordless cutoff / grinder. The specifications on this grinder are nothing new: paddle-switch; 9,000 RPM; tool-less accessory changes; etc.

December 16, 2024 -
I'm a Harry Owner type that does a fair amount of general metal work, auto body metal work, nothing too heavy duty but still use my angle grinder quite a bit.
I need to upgrade, so I'm thinking of a Milwaukee M18 Fuel Angle Grinder, but it seems there are so many models and options I need some advice and opinions about what options are worthwhile, especially the choice of trigger switches and the pros and cons of variable speed.
Any opinions and justifications of choice would be appreciated.

Worked in a metal fab shop using a 2880 grinder. It always did what I needed it to. I rarely felt the need to grab the bigger, plug-in grinder.

Agree on slide switch. I have the paddle switch, it always feels just a little unsafe when you're just moving it around with a battery on.

Best all around paddle switch, M18 FUEL, angle grinder? | The Garage Journal
April 6, 2022 - For a very long time Milwaukee made a corded angle grinder that had a really nice paddle switch along with a lock on button on the back of the grinder. I have at least two of them and really like them. This is the best of both worlds. The longer you have to grind the more you want the lock on switch. For short bursts you can' beat the paddle switch. If one of their cordless ...

New Milwaukee M18 Brushless Angle Grinder
Been a certified welder and a fabricator for the past 7 years and I absolutely love my Milwaukee cordless grinders. I have two of the 4 1/2”/5” FUEL braking angle grinders. One of them is recent, and the other I’ve had for 5 years now. Definitely will outrun your charger if you’re grinding non stop but I seldom find myself needing to do that much grinding.

I want one, I use 28V, would be super handy for little zings here and there. just what i was thinking. cordless stuff is great but i try to use corded stuff for extended work. i think the grinder would be good for easy cutting jobs when you have something to chop off outside the shop maybe a padlock on a shed or something like that.
