Not overly impressed
I bought this in a "starter pack". Came with a 5 AH battery and this grinder for what my local stores are charging for just the battery. I was excited to use it as I work as a beat mechanic in an underground mine. Sometimes, having a cordless grinder is the difference of a couple of minutes to gain access to something vs. several hours. I'd used it a few times to cut rebar out from under a scooptram that got tangled up and I was more than excited to have it in my bag. I went to use it a few nights later to cut a 2' sch 40 pipe and it kept kicking out (with a brand new cut off wheel installed). Finally, I went back to the shop and grabbed my partners yellow cordless to finish the job. A few weeks later, I went to use it to cut off some 3/8'' bolts and it burnt itself out. Tool is only a couple of months old.

This is the first milwaukee tool that I have not been extremely happy with it. I understand a grinder has a tough job to do and making it cordless is just asking that much more of it, but I am really not impressed with the quality of this tool.

Bought the bare tool only, keep im mind i tried 3 different brand new batterys that seem to work just fine on any other milwaukee tool i own even my big impacts, but not this one.
After 10 seconds into a 1/16 thick piece of sheet metal it cut about an 1/8 of an inch into the metal and cut off. Its been about 24 hours and no natter what battery i use it doesnt come back on. My 17 dollar harbor frieght grinder cut a 1/2 inch peice of steel from a mobile home frame no problem.

This is an incredibly useful tool. It’s compact design allows for use in close quarters and it’s power allows grinding and cutting operations that rivals a corded grinder. I highly recommend this tool.

This one of my favirite tools.
I purchased this tool early 2018. I have used it at work and home. I use it as a grinder and a cut off tool. I ues it a lot, and I have not had any problems. I want to buy another one to keep loaded with a wire cup brush. I LOVE THIS THING!!!

Does Not Qualify for "Nothing but Heavy Duty"
I have owned many Milwaukee corded, old 18volt, M12 and M18 tools. My truck has Packout containers full of them. While I have generally been very satisfied with their quality, the 2680 cut-off/grinder does not qualify. It tends to consume batteries; I tried 3 different 5AH but did not try my 12AH versions because of weight issues. The real concern is that the motor easily overheats and the tool continually cuts out. I wrote to Milwaukee tech support describing the issues which also have been shared in other reviews. I returned the tool and ordered a heavier duty model 7180.

Big power in a small package
We also have every variation of the more expensive FUEL grinders. Once in awhile you just need this more nimble 4-1/2 M18. Great in tight spots. People complaining about power and run time aren’t using the right batteries. Get a 12, a 9, or at least a 5.0 amp hr battery. We abuse this in industrial settings and it just won’t quit. It’s probably cut 200’ of 1/4 mild steel.

Handy 18V angle grinder.
Sweet angle grinder. Plenty of power. Like the quick detachable wheel guard. Might have preferred a standard on/off switch but the paddle switch isn’t a deal breaker. It operates satisfactorily after you get used to it. My first cordless grinder. It sure feels great not to drag an electrical around.

Great Tool for Off-Grid Grinding
Grinders use a bit of power, but this Milwaukee 18V Cordless Grinder gets a lot of use between charges. It's heavy, but the weight inspires confidence that it will last a long time on jobsite conditions. Easy to adjust guard throws debris out of the way, and a screw in handle provides good positioning. Too bad I've probably got 6 of these Milwaukee handles. The only downside is that the wrench doesn't have an onboard storage location.

How long does one of the 3.0 batteries last on a full charge??
Logan on Apr 30, 2016
BEST ANSWER: Depends on what you are doing.
If you’re cutting steel with a cut-off wheel, about 20 minutes of work. If
you’re cleaning up welds with a fladder or surface grinding wheel, much
longer, about an hour.
