Excellent Tool, Excellent Quality!
Great for cutting or grinding, I primarily use it for quick precise wood carvings. Great tool, but it will eat up batteries

Super Grinder/ Cut Off Tool
All my tools are Milwaukee 12 and 18 volt so when I had the opportunity to purchase the 2780 I did. I have used it a couple of times since purchasing it and like every other Milwaukee tool I have, it is great. Love the power it has. The paddle switch is awesome

This tool works as hard as I do.
This is actually the 3rd one I've bought. The 1st one I bought had many, many, many miles on it before it finally quit (5 years later .
These M18 FUEL models do an amazing amount of work in truly the harshest conditions. I've had mine in the rain (many times), extreme cold conditions, extreme heat conditions (S.W. Missouri & NW Arkansas weather) and I think I can truly say it doesn't seem to affect the life of the tool.
These tools work as hard I do.

Best thing ever.
I came from a M18 brushed grinder. And no I have the brushless one. All I can say is the power difference is unreal.

Great for cast iron pipe
I was doing demo of an entire cast iron waste system in a crawlspace and carbide blades were taking too long. I have a corded grinder but didn't want to deal with dragging cords underneath and I was trying to move quickly in this job. Got a thin diamond blade and completely demoed that system with one 4.0 battery in no time. Didn't bind and had the guts to cut through the cast with ease.

I would recommend this tool
Have not used a lot yet but what I have it's a nice fit in my hand. Seem to have plenty of power, paddle switch with retainer is very nice. Run time should be good as all my other Milwaukee m18 tools.
