Great tool, good value
Very good tool! One of the best battery powered ones you can get. Price is reasonable as well. Have not had any issues with it.

Great grinder and has just as much or more power as my corded grinder. I also feel less vibration in my hands compared to other grinders. The paddle switch is okay but i wish they had a trigger switch instead. Overall it is a product that i would recommend.

I love everything about this grinder. It has plenty of power it's cordless I've tried DeWalt and Bosch and nothing compares to a Milwaukee. My tool box is full of Milwaukee tools and I would not choose anything else

Great Grinder with lots of power.
This grinder is great. It's cordless but has lots of power. I like the paddle switch as it allows you to wear gloves and operate the tool safely. I am a hobby welder and really enjoy this tool. It's one of many Milwaukee tools I own.

It's an awesome tool
I use this tool daily, rarely ever use my corded versions. I had one that wore out the bearing in the gear box in less then a month though. The one I had before got used hard for over a year and the one I'm currently using has also lived the same lifestyle for a few months and still going strong. I'm a fan

I use it mainly as a cut off tool. But now I have two of them and use one for a cut off to and one with a twisted brush for welding on old equipment. I do use it with a regular grinding wheel and a sand flap wheel.

Is this compatable with the HD9.0 battery?
Jimmy S on May 29, 2019
BEST ANSWER: It is compatible with any M18 Milwaukee battery. The heavier 9.0 battery could make it a "handful," affecting the balance of the grinder.
Will this work with a normal 18v battery or does it have to be the XC 4.0
Ross on Dec 23, 2014
BEST ANSWER: The grinder will work with any M18 series battery
