Goodbye FlexVolt, Hello, Milwaukee Fuel
7 months ago
One powerhouse of a grinder. I ended up giving up on my DeWalt FlexVolt grinder. I get all the power with my new Milwaukee Angle Grinder and nowhere near the weight. I’m enjoying this. Very much. I’m going to be doing a lot of tool reviews as I’ll be exchanging my DeWalt for Milwaukee. I have a long way to go but I’ll get there.
Yes, I recommend this product.

Great Tools
8 months ago
The grinder is great, it was a replacement for one that my husband wore out after years of hard use.
Shipping left a lot to be desired, it didn't move for 2 weeks until I filled out a survey then couldn't be delivered to me and wasn't left where I told the guy to leave it so I had to go on a treasure hunt around town to find it

Commercial grade grinder
a year ago
I have retired all my other grinders. I wish i had not waited so long to purchase this amazing tool.I have a bad habit of abusing my tools. With Milwaukee tools it seems like the tool will abuse me. This grinder is a shop tool and employees will take it home for personal projects. I hear nothing but praise for this grinder.

Almost perfect
11 months ago
Great grinder. Powerful enough for what I need, and then some. My only complaint is with the paddle switch. It’s just kinda awkward. I definitely prefer a regular switch like you’d see on most other angle grinders. But all in all it’s a good, well made tool. The only reason I couldn’t give it 5 stars was the paddle switch.
Yes, I recommend this product.

Great but battery hungry
a year ago
The grinder seems good. I have only used it once so far to cut off about 20 pieces of rebar. I took one star off because it went through an 8 AH battery and 3/4 of another to do these cuts. I am not sure what they were cutting to get to the 135 cuts. All in all it made short work of the job and I would buy the tool again.
Yes, I recommend this product.

Cut the cord
10 months ago
The convenience of a cordless grinder is totally worth it. I really didn’t think it would be that big of a deal but I find myself grabbing this grinder any time I need to grind. The auto stop of the wheel is a nice feature that I’m liking more and more. Grinder works like it should, has handled any task I’ve ask of it.
Yes, I recommend this product.

Good Tool
3 years ago
I like cordless tools. Cord is one less thing to drag around while working. I use the tool around the house. I have small jobs and can just grab the grinder add sanding wheel, grinder disk, cut-off wheel or concrete cutting disk and then I go. Tool seems to have more than enough power for what I have done so far.
Yes, I recommend this product.

Fuel for the win this time.
a year ago
Originally 5 years ago, I purchased a non Fuel grinder by Milwaukee by mistake. I had decided to go with it anyway and it handled large tasks quite well before overheating and dying 5 years later.
As with all Milwaukee M18 Fuel products, this grinder does not fail. Powerful, runs cool and makes big jobs small.
Yes, I recommend this product.

Exceeded Expectations - well balanced tool.
a year ago
This grinder has exceeded my expectations. Even with the 5Ah battery - the tool is well balanced and easy to handle and position for cuts in different situations. I was primarily using it for cutting through 1/2" rebar and it did it without hesitation. After making about 40 cuts, it still had over half battery.
Yes, I recommend this product.

Best grinder on the market!!
a year ago
This grinder is great! It has plenty of power to drive though whatever the task at hand is. The braking system on it is great too, you let off the paddle and she stops! Great safety feature for when others are working around you and you don’t want the grinder taking off across the shop floor when you set it down.
Yes, I recommend this product.

Amazing convenience no down side
6 months ago
I love this grinder, I wish is used X-Lock besides that I really can’t complain, I tend to use my electric grinders but if it’s something quick I don’t want to drag extension cords out, or working where there is no power, this is amazing, plenty of power, uses my other M18 batteries, keep up the good work

Milwaukee Grinder used for grinding,cutting metal
2 years ago
This grinder works great it has a lot of power and the battery last long the tool feels sturdy and well balanced . Highly recommend it for cutting metal or cutting tile. The size is compact and doesn’t take up too much space in my toolbox. The only thing it’s missing is a carrying hook to carry on my pouch
Yes, I recommend this product.

Great grinder, needs more then a 5amp hour battery
a year ago
I have owned the grinder for two weeks now and it great for sanding and grinder small parts. The paddle switch works but your hand get sore from holding it the whole time a locking switch would be great. Unfortunately a 5amp hour battery only last and hour or two the grinder needs an 8amp to run all day.
Yes, I recommend this product.

Must have for metal work and time saving
2 years ago
Lighter than expected with the 6.0 ah battery. Simple to use and easy to adjust the guard to whatever position needed. Paddle response is great for adjusting the needed speed. From cutting chainlink fence poles to knocking off rust to a smooth new metal finish. Definitely will be put to many other uses.
Yes, I recommend this product.

Upgrade!
2 years ago
This grinder is a big upgrade from the non-fuel option with better run-time on the same batteries, a much nicer handle with a spring in it to absorb vibration, & a non-marring cover to the shield. There was a lot of good thought put into this fuel version of the M18 4 1/2 grinder. I am happy I upgraded!

Must have
a year ago
I went back and forth between the paddle switch and the on/off switch. I went with this paddle switch and im glad. The paddle to turn it on is the perfect size being big enough to locate and not strain your palm. The thing stops so quick its crazy. No problem with cutting power either. Would buy again.

M18 Fuel 4-1/2" Grinder
a year ago
I had to replace an older model M18 grinder. I liked the features especially the paddle switch is user friendly even with gloves on. The guys on the crew really like the power and braking too. They were also cleaning stubborn concrete off shovels with the wire wheel, I just hit them with a hammer....

Fantastic grinder!
3 years ago
I have already pushed this grinder hard and it has held up remarkably well! Not quite as much power as a corded unit, but it seems to have more torque and the true versatility of the grinder is that I am not tied to an outlet. If I ever manage to break this grinder, I will most likely buy another!
No, I do not recommend this product.

Spark deflector/Grind guard
2 years ago
Great build quality and power when using just a 4.0ah batt, however the reason for not 5 star. The spark guard works as it should but it’s not a nice fit. I’m rather embarrassed, the way it flops around when locked in place not sure if this is random on mine on if all have this problem feature no

Grinder
3 years ago
It does what you need it to do, the paddle switch I think is the the best part of it. I hope the moving parts of the switch last, but with a five year warranty there’s really no reason to worry. I don’t use this tool every day but I’m glad I finally have a grinder in my arsenal of 18v tools.

Great features.
a year ago
Easy to adjust guard allowing you to use the grinder at any angle you wish.
The handle can screw into both sides for right/left hand use.
Paddle switch is an easy to use safety feature that came in handy when accidentally bumping into something and losing grip on grinder, shuts off fast.
Yes, I recommend this product.

Great Grinder!

Great grinder, a xc5.0 battery lasts for a good long while! I do see why the angled head and slim profile one was a bit more expensive but if your not trying to grind in tight spaces this one is perfect. The auto stop function comes in handy for quick handling as well, overall 4.5 out 5.

Not a lasting safety

The auto stop feature stuff working within a week... The grinder overall is a fantastic tool however this purchase just need specifically for the safety feature which does not last. I currently own three of these grinders and not one of these had the safety feature last more than a week.

The best grinder made
2 months ago
This is a superior product compared to other brands. Well built and a super dealer network. So much safer than an electric corded model. I use mostly thin cuts and have never had one explode with this grinder. This model has the quick stop and I like that making it faster to set aside.
Yes, I recommend this product.

Lots of power

This is an awesome grinder. This is the first grinder this type that I’ve ever owned and so far I love it. I’ve only used cut off wheels in it, but I can see it’s potential. Comfortable to hold the paddle trigger is a nice feature. Ramps up to speed quickly and brakes quickly as well.

M18 Fuel 4 1/2 inch grinder

I bought this grinder a few weeks ago because I needed a new one for work. All of my cordless tools were Milwaukee so it was a no brainer to buy another one. I’ve put a lot of hours on it already, never had a complaint. I will recommend you buy 5.0 or 6.0 batteries with it though.

Great Ergonimics

I chose this grinder for several reasons over other brands for multiple reasons. One of the deciding factors was the overall ergonomics that it has. The weight balance, along with the paddle gives a comfortable and controlling feeling even with arthritic hands to get the job done.
